This is a sturdy, well-made camera from Vivitar. It was not made by Vivitar but is a rebadged Cosina 35 and was available under several other camera marques as well - Cosina, GAF, Argus, Prinz, to name a few. It dates from the 1970s and some Interweb sites suggest 1976 - I cannot date it anymore accurately that that.
The camera measures 115 by 78 by 33 mm body with the lens included it is 115 by 78 by 53 mm. It weighs a hefty 410 g. The body is all black - mainly covered with black leatherette with the top and bottom plates painted black gloss. The main body is cast aluminium alloy, the top and bottom plates are brass and the back is steel.
On the far right of the top plate is the frame counter window. This resets to 'S' when the back is opened - effectively to -2. The numbers are in white - just the even numbers are displayed - with 12, 20, 24, and 36 displayed in red as these were the usual 35 mm film lengths. After frame 36, the counter no longer advances.
Just to the left of this window is the film advance lever. This is metal with a plastic tip and is fixed on the top of the top plate. In use, this lever sits just proud of the top plate allowing the user's thumb a good grip. When not in use, the lever will park out of the way over the top of the plate. The shutter release button is forward of and slightly to the left of the film advance lever. This button is chrome plated and threaded for a standard cable release. The film advance and shutter release are linked together so that film cannot be advanced without firing the shutter and the shutter cannot be fired without advancing the film.
To the left of these, the top plate is slightly raised to accommodate the rangefinder mechanism. On top of this raised part is the accessory shoe. This is X synchronisedfor electronic flash - signified by a red 'X'. On the left hand edge of the top plate is the film rewind crank. This is the usual small folding crank and doubles as the catch for the back - it opens the back by being lifted.
The back of the top plate has the viewfinder window. This measures 10 by 6.7mm which is plenty for ease of use. Inside the viewfinder, the screen is larger than the image - the image is delineated by bright lines. In the top left of the viewfinder image are secondary bright lines to account for parallax with close-up photographs.
In the centre of the viewfinder image is a yellowish-green square. This is the rangefinder patch. Any part of the image within this patch that is not in focus will be split into two images. To focus the camera, you turn the focus ring on the lens until the part you want to be in focus consists of just one image. There will be more about this a bit later.
On the right hand side of the viewfinder image is the light meter readout. There are two vertical scales - the left hand one is the shutter speed and the right hand one is the aperture. There is a needle which swings up or down to the selected shutter speed/aperture pair. The slowest shutter speed is 1/30 seconds which is always coupled with ƒ/2.8 as is 1/60 seconds. 1/125 is at ƒ/4, 1/250 is between ƒ/5.6 and ƒ/8 and 1/650 is always at ƒ/14. For a given light level, the user gets no say in either shutter speed nor aperture. The reason that the shutter speed and aperture are so firmly linked is that the shutter blades double as the aperture blades - opening the shutter further takes longer and gives a wider aperture. The scales have a red portion at top and bottom to indicate that light levels are outwith the camera's capabilities.
The front of the top plate has two windows. The larger, 13 by 10 mm, is the viewfinder window. The other window has two functions. Mostly, it is covered with a translucent grey material. this provides the illumination for both the bright lines and the light meter display. In the middle of the translucent material is a transparent square. This is the rangefinder window which provides the yellowish-green patch mentioned earlier. The colour of the patch is the result of using gold to make the interior mirrors rather than silver.
The accuracy of a rangefinder depends mostly on how far apart the centre of the rangefinder window is from the centre of the viewfinder window. On this camera, the spacing is 25 mm which is rather close (for reference, my Zorki 4 has 40 mm, my FED 2 has 68 mm, and my Yashica Minister-D has 35 mm). This closeness means that this rangefinder will not be very accurate - but will still be better than most people guessing distances.
In the centre of the front is the shutter/lens assembly. The diameter of the assembly is 51 mm. There is no indication as to who made the shutter (but I have a suspicion that it was Copal). There are two control rings on the assembly. The inner most ring has an auto setting and five flash guide numbers. In normal use, this has to be set to 'auto' for the exposure system to work - there can be no manual operation of this camera. The outer ring is the focus ring. Normally, you would use this while looking through the viewfinder and using the rangefinder but you can set the subject distance directly on the scale on the ring.
The bezel of the lens has two important items on it. Just above the lenses the window to the light meter sensor. This is a CdS sensor and so needs a power source to work. This is provided by a mercury battery giving 1.35 volts. Unfortunately (or fortunately as far as the environment is concerned) mercury batteries have been banned world-wide and the modern alternatives give 1.5 volts. This is going to cause the camera to get the exposure wrong. I always find that the 'wrong' exposure is within the exposure latitude of film and so I just use an alkaline battery. People who are fussier than I am can adjust the film speed to compensate. This light meter sensor is within the filter thread so if a coloured filter is used, the meter automatically compensates.
To get the light meter to work correctly, it is necessary to set the film speed. The film speed window is in the bezel below the lens and displays the film speed in DIN (red) and ASA (white). This can be set from 16 DIN/32 ASA to 27 DIN/400 ASA. To change the set film speed there is a knurled ring around the lens. Also on the lens bezel is the information that the camera uses 46 mm filters, the lens has a focal length of 38 mm (slightly wide of 'normal') and has a max aperture of 1:2.8 (which is ƒ/8). On the b bottom of the shutter/lens assembly is a small chrome tab. This presses in to free the inner ring to allow the user to change from Auto to a flash guide number. There is a good orange index line for the auto position and an orange 'lightening flash' plus dot for the guide numbers.
To the left of the shutter/lens assembly is the delay action lever. To set this you turn it anticlockwise and to activate it you press the shutter release button. This provides a delay of exactly ten seconds.
The base plate of the camera is brass painted black. In the middle is a standard 1/4 inch UNC tripod socket. Beside this is the battery compartment. This should contain a mercury cell as already mentioned but this camera came with a silver cell in place and I shall leave it there. Also on the base plate is the button to disengage the film advance mechanism to allow the film to be rewound.
The leatherette on the back of the camera has a Guide Number chart. This just seems to be distances with no reference to actual guide numbers. Below this is the camera serial number - 048305795 - and the legend "Japan' to indicate that the camera had been imported.
Opening the camera (by pulling up on the rewind crank), the back hinges well away from the body. This is a Japanese camera so there are foam light seals to keep the back light tight. This camera is over 40 years old and these foam light seals are well on their way to turning into sticky goo. They will need replacing before this camera can be used in anger. There is a groove top and bottom of the body which contains the thin strips of foam - the top groove has a small button in it at the right which resets the frame counter as the back is opened. There is also a strip of foam by the hinge and a large, thick piece of foam by the catch. This last not only provided light tightness but also keeps the film cassette in place and stops it wobbling about as the camera is used.
The film cassette goes on the left. In order to insert a new cassette or remove a used one, it is necessary to pull up the rewind crank. The film gateis nicely finished and smooth. There is a sprocket shaft just to the right of the film gate. The sprockets allow the camera to move exactly the right amount of film for each new frame. Next along is the take-up spool. This is wide so it will not tightly curl the film. There are four fixing slots around the take-up spool. The only other thing I can see inside the back of the camera is a small screw above the film gate, right on the left. This is a blanking screw. Removing it reveals a small hole which gives onto another, smaller, screw. This smaller screw is used to adjust the rangefinder for infinity focus.

Exa cameras were a cut-down version of Exakta cameras. The first Exa version was just called Exa with no numbers – the second version was called Exa I. This first version Exa was produced in six varieties and my camera is the sixth variety – hence my title above of Exa 6, but the makers, Ihagee, never called it Exa 6 (nor exa 1.6), it was just plain Exa.

Exa, and Exakta, cameras are unique in body shape, control layout and internal mechanisms. If you are used to a Japanese style SLR, Exa take a bit of getting used to. The most obvious difference is the shape. It is rhomboidal rather than rectangular and a lot thicker than other cameras. Another obvious difference is the shutter speed selector which is a lever. The last obvious difference is that the camera is left-handed. The speed selector is left of the viewfinder and the shutter release button is left of the lens.
As this camera is so unusual, I am going to give a very detailed description.
The camera measures 130 mm by 48 mm by 85 mm including the viewfinder but excluding the lens. It weighs 528 g.
Looking at the top plate, the viewfinder is central. Most SLR cameras have the lens and viewfinder somewhat left of centre. This camera has them centrally. The viewfinder is removable and can be replaced by various models. My camera has a waist-level finder but several eye-level finders were available (all viewfinders and focus screens for Exakta and Exa models should fit apart from those for the Exakta RTL1000). To remove the finder, it is necessary to move a slide downwards to release the fitting. This slide is on the front panel above the lens and just below the name plate. To fit the viewfinder, it just pushes into place.
When not in use, the waist-level finder folds down which makes the camera significantly smaller and prevents dust from falling on the focus screen. To open the finder, there is a small chrome button on the back of the finder which needs to be pressed in. The finder then snaps into the open position.
To use the waist-level finder, you look down into the finder at the focus screen. My camera has a plain ground glass screen (actually, it is a plano-convex lens with the plane surface ground to form the image and the convex part providing some magnification) but, again, other options were available including one with a split-image centre. The screen is easy to remove and replace – detach the finder from the camera and the focus screen is at the bottom held in place but springs but not very securely – a gentle pull and out it comes.
The image in the waist-level finder is reversed left to right but it is the right way up. There is no pentaprism here to correct the image. At first, this makes composing the image awkward but one soon learns to use it easily. Having the camera away from the eye changes the perspective of the image and looking down at the image also alters your reaction to it. I find that this makes a significant difference to my composition, and, talking to other photographers, this is quite usual.
The big drawback to having the camera away from your eye is focusing. To aid this, Ihagee have supplied a folding magnifier to enlarge the finder image. Raising the camera towards the eye makes focusing easy and you can then lower the camera again to take the shot.
On the right of the viewfinder is a nickel plated plate. Prominently, this carries the film advance knob. This requires one complete turn to advance the film one frame and to lower the mirror (more later as this part is seriously stranger). This knob is also nickel plated which I rather like. Nickel is bluer and softer than chrome plating and much more attractive in good condition. Unfortunately, nickel is prone to corrosion and on my camera is very corroded. When I cleaned the corrosion off, I was left with heavily pitted surfaces.
Beside the advance knob is the frame counter. The disc of this is also nickel plated and corroded. It is both hard to clean and cleaning has partially removed the numbers. This counter counts up and needs to be manually set to 1 when fresh film is loaded. There is a little serrated wheel to do this but this is hard to reach and turn.
Behind the frame counter is the button to release the film advance mechanism to allow the film to be rewound.
On the left of the viewfinder is another corroded nickel plated plate. This carries the shutter speed selector. Unusually (apart from Exa being the only cameras I know with the speed selector on the left) this is a lever. Speeds are sparse – 1/25 to 1/150 seconds plus B. Asahi were offering 1/1000 on their Pentax cameras at this time. This speed selector is relatively stiff (my camera or by design?) and has very definite positions. Beside this lever is the film rewind knob. Again, a knob here was already old-fashioned at this time but I find it as easy to use as the more usual fold-out cranks.
If we move to the front of the camera – the lens mount is on a nickel plated plate in the centre of the front. At the top of this plate is the name plate. This is painted black with the name “Exa” in script and bright metal. Beneath this is the slide catch for the viewfinder – also nickel plated. Either side of the slide the words “IHAGEE DRESDEN” are stamped in the metal.
On the left side of this plate (as in using the camera) is the shutter release button. This is threaded for a standard cable release. Beside this is a swivel cap which functions to block accidental pressing of the shutter release.
Central in this plate is the lens mount. This is a standard Exakta/Exa bayonet with three lugs inside the throat that connect with the lens. With my Exakta Varex II and my three other Exa cameras, there are three extra lugs on the outside of the mount throat. These are to connect longer focal length lenses as using the internal lugs caused vignetting with lenses over 100 mm focal length. These are missing on this camera so using lenses over 100 mm focal length would be problematical. On the left side of the mount is the lens release lever.
This is probably a good place to talk about the lenses. The standard Exakta/Exa lenses are automatic in that the iris diaphragm automatically closes as the shutter release is pressed. The way this is achieved is very idiosyncratic. The lens has a shutter release button attached to one side which sits immediately over the shutter release button on the body.
When you press the release button on the lens, this pushes through the fitting on the lens and presses the release button on the body. It also closes the iris diaphragm in the lens at the same time.
On the right hand side of the lens mount are two PC sockets. These are chrome plated. The top socket is for F rated flash bulbs (F=fast) and will fire the flash bulb 12 milliseconds before the shutter is fully open. This is to allow the flash bulb to reach maximum brightness as the shutter fully opens. This requires a shutter speed of 1/25 seconds.
The lower socket is marked X and is for electronic flash (X=Xenon which is the gas which electronic flash tubes are filled with). With the X socket, the flash is fired as soon as the shutter is fully open and needs a shutter speed of 1/50 or 1/25 seconds.
The back of this camera is hinged – on my other Exa cameras, the back is completely removed together with the base. When you open the back, the ends of the base come away with it, leaving the middle portion in place. The reason for this is to allow easy insertion and removal of the film cassettes. As you can see from the photograph, the back of my camera is rather tatty. Leatherette frequently comes loose – it was stuck on with shellac – and is easy to refit. Unfortunately, the previous owner of my camera used a plastic type glue and the solvent has reacted with the leatherette and shrunk it.
In common with a lot of German cameras, it is possible to remove the take-up spool and replace it with an empty cassette. This removes the need to rewind the film and speeds up changing the film – it is necessary only to cut the film and remove both cassettes. In order to make use of this fast film change, you need your new film to be already attached to an empty cassette. Quite doable but it would require more organisation than I am really capable of. The down side of this system is that the detachable take-up spool gets lost resulting in second hand cameras being hard to use. The inner from a standard cassette will fit fine but unless you do your own developing, can be hard to find.
The base of the camera is plain apart from a tripod socket. This is a 1/4 inch Whitworth threaded socket.
Being a German camera, there are no light seals to deteriorate, the Germans preferring to achieve light-tightness by good engineering.
The shutter is worth describing – this is also unique to Exa cameras. This shutter is neither an in-lens leaf shutter nor a focal plane shutter. It is a guillotine shutter using the mirror as the first part of the mechanism. When the shutter release button is pressed, the mirror moves up through an arc, exposing the film. A curved blanking plate then swings up and finishes the exposure. Once the exposure is complete, the mirror stays raised until the film is wound on. This is the reason for the rather slow top speed of 1/150 seconds as it is not really possible to get the heavy mirror moving fast enough to get a faster exposure. Plus points are that it is cheap to make, keeping the cost of a new camera down, and has no need of lubricants and so can be used in very cold conditions.
|My Final Word||The Ihagee Exa 6 (or 1.6) camera is a unique camera. Controls are simple and the idiosyncratic. Once you are used to it, it is a delightful camera to use although the slow top shutter speed can be restricting. I like Exa cameras!|

There are no manual controls apart from focus. Shutter speed, aperture and film speed can all be set manually but only through the automatic systems. This is much slower and less intuitive than having a shutter speed dial and aperture ring. There are no dials, knobs or rings on this camera. All adjustments are made with a combination of buttons and sliders.
Really, this was the main design flaw here. Where the Canon EOS range introduced the general-purpose dial just behind the shutter release button (which has subsequently been adopted by all DSLR manufacturers), this camera has a slider. To make an adjustment, you repeatedly slide and release – either to the left (to reduce a value) or to the right (to increase a value). Frequently, this requires the left hand to simultaneously press a button which is not as fluid a motion as Canon’s system (I am going to reference the Canon EOS system quite a bit).
|Lens mount showing 'screwdriver on lower right|
Focus is achieved by a motor just inside the lens mount – this engages with the lens by a small ‘screwdriver’ much as Nikon still use on some DSLR bodies. This ‘screwdriver’ retracts when the focus is set to manual.
Time for a description:
The right-hand end of the top plate is dominated by a LCD display. This contains all the relevant information – not all of which is displayed all the tie. At the front of this display is the exposure mode: Program, Av, Tv or M. In the middle is the frame counter, shutter speed and aperture. Behind this is the drive mode (single, continuous or delayed) and focus mode (AF, CAF or M)
In front of this LCD is the mode selector slider. This is not marked as to its purpose making the manual very useful. In front of the selector slider is the shutter release button. This is a soft rubber. Beside this is a small grey button marked ‘P’ – this small grey button will set the exposure mode to program and turn on the beeper. This is very slightly easier than using the ‘mode’ button and selector slider. Behind the LCD on the back of the top plate is a threaded socket for a standard cable release. This fires the shutter as you release the cable release plunger rather than as you press it.
|Cable release socket|
In the centre of the top plate is the pentaprism hump. The top of this has a groove on either side to locate the dedicated flash unit – more later. On the front of the pentaprism hump there is a translucent window to provide light for the viewfinder LCD display. When the dedicated flash unit is in place, this window is covered and the LCD is illuminated by three small lights.
|Hot shoe with grooves for fitting flash unit|
On top of the pentaprism hump is the accessory shoe. This is a hot shoe – it has the standard central contact and so should work with any hot-shoe flash gun. In addition, there are five more contacts used specifically by the dedicated Yashica flash unit.
On the left of the pentaprism hump are the remainder of the controls. Right up to the pentaprism is the on/off slider. This moves all the way forward to switch the camera on and half-way for the AE-L setting – more later. The other controls are buttons, these are used in conjunction with the selector slider on the right of the top plate. They are: mode, AF, drive, +/- (exposure compensation), ISO and beeper. The ISO button is an override for the DX system that reads film speed off the cassette and sets it automatically. This is useful if you want to set your own EV for the film instead of rating the film at the manufacturer’s rating. Also if you are using bulk film loaded into black cassettes.
|main control buttons|
Just in front of these buttons, on the side of the lens mount, is an unmarked button. This is used in Manual mode to help set the aperture. In manual, the selector slider sets the shutter speed, and in conjunction with this button, sets the aperture. This is quite a clumsy arrangement, to say the least.
Continuing down the side of the lens mount, there is a large button with a red dot. This is the lens release button – when this is depressed, the lens can be rotated anti-clockwise 45 degrees and then removed. Below this is the auto/manual focus selector. Twisting this slightly anti-clockwise retracts the focus ‘screwdriver’ and allows the lens to be focussed manually.
The only item on the front of the camera is the lens mount. This is a three blade bayonet mount – pretty much standard from the 1930s to the present day – with the auto-focus ‘screwdriver’ on the lower right. In 1975, Yashica had joined forces with Zeiss to produce a series of Contax cameras with a new bayonet mount called the C/Y mount (not to be confused with Zeiss Ikon’s 1936 Contax cameras with a totally different bayonet mount). With this camera, Yashica decided to produce a new mount which is not compatible with the Contax mount and is only used on this camera.
Just inside the mount at the bottom is a lever which sets the required aperture on the lens. There is no aperture setting ring on the lenses for this camera – as is now usual for nerly all new cameras. At the top of the lens mount are five electrical contacts. As there are no electrically active components in the lens, I assume these contacts allow the camera’s processor to read zoom and focus positions.
Also worth noting is the fact that the focus screen is replaceable. There is a small catch at the front of the focus screen and when this is released, the frame holding the screen in place swings down and the screen can be pulled out. I am not aware of other screens being available but this facility might be for future development if this camera had sold well (it didn’t).
I only have one lens for this camera – a35-70 mm zoom. This is a fairly useful range on a 35 mm camera. It has a 52mm filter thread at the front. It claims to be a macro lens – many lenses falsely make this claim – and it certainly focusses down to about 200 mm at the 35 mm focal length and a bit closer at 70 mm. This does not give true macro (image size on the film/sensor the same as the subject size) as the smallest subject that will completely fill the 36 mm film frame is 180 mm but it certainly gives close close-ups.
|bayonet on lens showing contacts|
The lens has four focus indexes (yes, that should be indices) – one in white for normal focusing, one in red for focusing infra-red images at 70 mm, one for infra-red at 50 mm and one for infra-red at 35 mm. The way these indexes work is this: first focus the object normally and read the distance scale by the main white index mark. Next, move the focus ring until that distance is against one of the red infra-red indexes. The image will now appear to be out of focus to the human eye, but the image on infra-red film will now be in sharp focus.
|Infra-red focusing indexes|
The last item is the dedicated flash unit. This slides onto the hot-shoe from the front (the opposite way to usual). When it is in position, you depress and slightly turn clockwise the red and black button on the rear of the flash unit. This locks it in place firmly and pushes all six of the electrical contacts down onto the corresponding contacts in the hot-shoe. There is a grey slider on the top of the flash unit – sliding this to the right turns on the unit. It is powered by the camera’s battery. At this point, operation is entirely automatic. There is no need to worry about the synch speed for the shutter or which aperture to use. This photo of the kid’s bike was taken with this flash unit with the camera set to Av mode (aperture priority mode).
If you wish to use the camera in manual mode with this flash unit, there is an aperture guide on the top of the flash unit. To use this, you guesstimate the distance to your subject and read off the corresponding aperture. Even in manual mode, the shutter speed is automatically set to the synch speed which is 1/90 seconds.
|flash unit in place|
Inside the camera holds no surprises. There is a vertically travelling metal focal-plane shutter. The cassette space is on the left. There is the standard row of six sprung electrical contacts to read film speed and length of the DX code on the cassette. To load the film, you pull the leader to the red line and close the back. When you switch the camera on, the film automatically advances to the first frame. When you want to rewind the film, there is a button and slider on the base – press the button and slide the slider to the right and the film will rewind.
|yashica 230AF insides|
What else? A couple of things. There is a clear window by the film cassette to you can both see if a film is loaded and if so, what type. On either end of the camera is a strap lug allowing the attachment of a neck strap - but what I have never seen before, there is a third strap lug on the left near the base. This will allow the camera to hang sideways or you could attach a shorter hand strap.
I have run a roll of Agfa Vista+ colour film through the camera with no hassles at all. The camera turns out to be quite easy to use even if not intuitive. I am quite impressed with the results.

This is Voigtlander's attempt to cash in on the Rolleiflex design. As well as this cheaper model, they also produced a much more expensive model called the Superba. This camera looks exactly like a TLR (Twin Lens Reflex) - and it is: it has two lenses and the viewing lens is reflex; it looks via a mirror. he big difference is focussing. Rolleiflex and their cousins focus by moving the front plate (with taking lens and viewing lens) back and forth and the user focusses via a ground glass screen which is missing on this model. Here, focussing is via a helical screw thread on the taking lens.
|Voigtlander Brillant, front view|
This camera is made from Bakelite (an early plastic) which becomes brittle with age. My camera is in very good condition with no visible cracks. The only damage I can see is one of the strap lugs has snapped off.
My usual technique with this blog in describing cameras is to start with the top plate and work my way down. Right at the top is the maker's name 'Voigtlander' in Italic script. Below this in the front panel are two lenses. The top lens is the viewing lens (essentially the viewfinder) - the user looks down on the top of the camera and through this lens via a sloping mirror. There is no focussing screen and this lens is fixed (there was a more expensive version with a focussing screen).
Below the viewing lens is the shutter assembly with the taking lens. The shutter has the AGC logo telling us that this is a Gauthier shutter - in fact a Prontor II going by the range of shutter speeds.
|Gauthier shutter (Prontor II)|
As always with older clockwork shutters, it is necessary to cock the shutter before use. There is a lever at the top of the assembly for this purpose - the user pulls the lever down to the right (in use; to the left, in my photo of the shutter) where it stays until the shutter is fired. Just below this cocking lever is the shutter release lever. This release lever pushes down and in. Below this is a threaded socket for a standard cable release.
The shutter has two ranges of speeds operated by different parts of the shutter mechanism. The fast speeds - 1/25, 1/50, 11/100 and 1/175 seconds - are working well on my camera and seem to be close to the marked speed (test film will tell for sure). The slow speeds are usually hesitant or non-functional on old shutters. These are 1 second, 1/2, 1/5, and 1/10 seconds. These do not work on this camera without the user forcing the cocking lever back to its normal position. In addition to the fast and slow shutter speeds, there are two more. B keeps the shutter open while the user keeps the release lever depressed (or more likely in practice, keeps the cable release depressed). T will open the shutter when the shutter release is pressed and the shutter will stay open until the shutter release is pressed a second time. B and T work well on this camera.
The taking lens is a Voigtlander Vaskar. This is Voigtlander's cheap triplet (a Crooke's triplet design as far as I can tell). Triplets usually perform very well if stopped down to f/8 - the test film will show for sure how well this lens performs. The focal length is 75 mm which is 'normal' for TLR cameras. The negative is square - nominally 6 cm per side. 'Normal' is the diagonal of the negative. Pythagorus gives us a diagonal of √(36+36) = √72 = 8.5 cm so this lens is very slightly wide angle. Maximum aperture is f/4.5 (very respectable for a cheap camera in 1950) and the minimum aperture is f/16. The aperture is set by a lever on the shutter assembly on the photographer's left. At the base of the shutter assembly is the delay action lever. As with the slow shutter speeds, these rarely work well on old cameras and the standard advice is to never try them.
Below the shutter assembly is the camera's model name - Brillant (not Brilliant!).
The left side of the camera has a hinged door with space inside for two filters/close up lenses. My camera has one yellow filter in place - these are a push fit on the taking lens.
|Left side showing the filter compartment|
The right side of the camera has various controls. The most obvious is the film winder at the top. This winds the film on between shots. he lever to the right of that releases the frame counting mechanism while winding to the first frame.The lever in the middle sets the frame counter to 1 which is displayed in the small window. Detailed instructions on how these knobs and levers work can be seen in the instruction 'book' on my Google Drive (one small sheet of folded paper ).
|Right side showing controls|
On the back there is the ubiquitous red window that medium format cameras usually have. This is covered by an internal blind to prevent the film being fogged while not in use. This is opened by a knurled ring below and to the right of the red window. The blind has a large white cross on it to make it clear that the blind is in place. This red window is only used to position the first frame. Thereafter, the internal mechanism will move the film the right amount.

The bottom of the camera has a 1/4 inch Whitworth tripod socket. This sits slightly proud of the base, presumably to give enough plastic for strength. On the front edge of the base are two raised spots. Together with the raised tripod socket, these provide a stable base for the camera to sit on for long exposures or self-portraits.

The top of the camera has the viewfinder. In this style of camera, you look down into the viewfinder to compose the picture. In storage, the viewfinder folds down out of the way (see top two pictures above). To open, you lift the rear of the top piece - the other three pieces then rise under spring power.
There is no focussing screen as there would be with a Rolleiflex (because the viewfinder is not used for focussing) - rather, you look through a large square lens via an angled mirror and through the top lens in the front. This is, basically, a giant brilliant finder. The image is very clear and bright but significantly smaller than the negative size. The image is the right way up but reversed left to right. This takes a bit of getting used to but soon becomes second nature. On the left side of the viewfinder panels is a depth of field table (referred to on the camera as a depth of focus table).

The front panel of the viewfinder has a fold-down section. This is to allow the camera to be used as an direct vision eye level finder. These were referred to as 'sport' finders as the direct view is not reversed left to right, making following motion much easier. this fold-down section is used in conjunction with a punch hole in the read panel.
The back of the camera is opened by pressing together two chrome buttons on the top of the back. The back then hinges down in one piece with the base. The new film goes in a recess in the base, held in place by a leaf spring.
|inside the camera|
The roll of film is a fairly snug fit in here. The film backing paper is pulled over a small roller, across the film gate, across a second small roller and into the take-up spool. On the right hand edge of the film gate is a recessed toothed wheel. This is rotated by the film moving over it and serves to measure how much film has been advanced between shots - the red window only being used for the first frame.
