This blog consists of descriptions of my various vintage cameras and my experiences in using them.
I welcome your comments and additional information.
I am also happy for people to write their own reviews of their old cameras for inclusion in this blog.
My most recent acquisition is this Soviet Kiev 4. It is a straight copy of the Zeiss Ikon Contax III (with only very slight changes).
Kiev 4 - front view
At the end of WWII, the Soviet army had Zeiss Ikon rebuild their production line for the Contax and then, once the line was working properly, they shipped the production line to Kiev in Ukraine. They also renamed the camera Kiev. This camera is a Kiev 4 and is a copy of the Contax III - there was also a Kiev 4a which was a copy of the Contax II. The difference between the 4 and 4a is the presence of a light meter in the Kiev 4.
The Soviet Union produced cameras both for the home market and for export. Those intended for home consumption had their logos and indicators in Cyrillic while those for export used the Latin alphabet. My camera has the logo in both Cyrillic and Latin but other writing is all in Cyrillic, indicating that the camera was not intended for export (сделано в CCCP = Made in USSR )
The camera has a very Zeiss Ikon look about it and the body is broadly similar to the Pentacon F and Contaflex - both German derivatives of the Contax, the Pentacon F being East German and the Contaflex being West German (younger readers should consult their history books!).
The camera is heavy - 768g with the standard Jupiter 8 lens - and the controls reveal the camera's design date (1936). the film advance is a knob (usual in the 1930s, very old fashioned in 1969 when my camera was made) as is the film rewind. The viewfinder is very small, hard to use while wearing glasses and (because it is bare metal) likely to scratch modern plastic spectacle lenses. The last anochronistic item is the tripod boss which is 3/8 inch Whitworth. Standard for consumer cameras had been 1/4 inch for some tine (currently 1/4" UNC rather than 1/4" Whitworth but the two are close enough to be interchangeable).
The knob on the right hand end of the top plate has three functions
in the centre is the shutter release, threaded for a standard cable release.
around the shutter release is a knurled ring to wind on the film and reset the shutter.
The shutter speed selector - operated by lifting and turning the film advance ring.
The manual says that the shutter speed can be selected either before or advancing the the film but that it is better done after advancing then film.
Kiev 4 - top plate
Next to the right hand knob is a window showing the frame numbers. This is nice and large and shows 12 numbers with a red dot indicating the current frame. This counts up from zero and goes to 36. It is reset manually by a toothed wheel on the back edge of the top plate.
Being a rangefinder camera, there is no pentaprism hump but where you might expect to see one there is a light meter. This has a selenium sensor and so has no need for a battery. One drawback of selenium meters is that they can lose sensitivity with continued exposure to light. To prevent this from happening, there is a cover to the meter window on the front of the camera. thesis opened by pushing the cover slightly to the right when it will spring open.
On the top of the meter is the meter window. This has a central lozenge and -2 and -4 marks. The meter is used by turning the control knob on the left until the meter needle is centred on the central lozenge. The -2 and -4 marks are used in low light conditions - they are each one stop away from the central position. If there is insufficient light to get the meter needle to the lozenge, you line it up with the -2 or -4 and then multiply the indicated exposure by either one stop or two stops.
Also on the top of the meter is the accessory shoe. There are no electrical contacts here so this is a cold shoe. It was intended that this accessory shoe would hold an auxiliary viewfinder when longer focal length lenses were used. In the centre of the accessory shoe is the legend сделано в CCCP (made in USSR) and the serial number 6968008 which indicates that the camera was made in 1969 (the first two digits of the serial number being the year of manufacture).
Kiev 4 - accessory shoe
On the left end of the top plate is another multi-function knob.
The outer knurled ring adjusts the light meter.
The inner ring which is adjusted by two studs to set the film speed.
The centre is a pull up knob for rewinding the film.
The film speeds are indicated in гост which translates as GOST. This is basically the same as ASA (or ISO). The Gost scale is awkward as it does not have the usual ASA numbers. There is 65, 130, 250 and 500. Using 'western' film, ASA 100, 200 or 400 film requires guessing the position of the film speed selector. If this scale was in DIN, it would be 20 DIN (65 Gost), 23 DIN (125 Gost), 26 DIN (225 Gost), 29 DIN (500 Gost) which is probably the reason for the choices - the camera having been designed in Germany where DIN is usual.
The front of the camera is dominated (as always) by the lens mount. This is the Contax bayonet mount (not to be confused with the Contax/Yashica mount of SLR cameras). There are actually two bayonet mounts here. The 50mm Jupiter 8 lens fits into the mount and latches onto three lugs inside the mount. There is a second, larger, bayonet mount around the distance scale which is for longer focal length lenses.
Kiev 4 - lens mount
This lens mount is connected to the rangefinder and either rotates to focus the lens when the rangefinder wheel is turned (more later) or turns the rangefinder mechanism when the lens is turned. When the lens is focused on infinity it locks inlace. When locked, the lens cannot be focused. It can be unlocked in two ways.
there is a small pointed stud near the upper left of the lens mount which can be moved away from the lens to unlock it.
there is a lever by the rangefinder wheel which you depress as you turn the wheel.
On the right of the lens mount (right as in when using the camera) is a delay action lever. This rotates through just over 90 degrees to wind-up the action. It is activated by sliding a small button which is usually hidden beneath the lever. On the other side of the lens, just below the viewfinder window, is a PC socket for connecting a flash gun.
The rangefinder shares the same eyepiece as the viewfinder. To give as much accuracy as possible to the rangefinder , the two windows on the front are kept as far apart as possible (9 cm centre to centre). This is much further apart than on the Leica which was the main competitor when this camera was designed in 1936 and also than the FED and Zorki copies of the Leica.
Kiev 4 - rangefinder wheel
Just to the right of the light meter and slightly below it is the rangefinder wheel mentioned above. I find this very hard to use as when my index finger is on the wheel ready to turn it, my middle finger naturally falls over the rangefinder window, rendering it inoperable. For me, it is much easier to focus by turning the lens. The rangefinder spot is easy to see and is slightly yellow for maximum contrast. This yellowing is achieved by 'silvering' the internals of the rangefinder with gold.
For those who do not know, a rangefinder works by producing two different images in the viewfinder.
As you change focus, one of the images moves. To achieve accurate focus, you make sure your subject is in the centre of the viewfinder and turn the rangefinder wheel or lens until the two images are superimposed on each other. With practice, this is quick, easy and accurate.
Kiev 4 - rear view
To open the camera, it is necessary to remove the back and base as one unit. At home, working on a table, this is slightly easier than a hinged back. In the field, it is a nightmare. You need to find somewhere to put the back/base while manipulating the film. To make matters worse, the take-up spool is loose and liable to fall out.
The reason for the loose take-up spool is that it can be replaced with an empty cassette, removing the need to rewind the film when finished. This gives a faster reload time - good for studio work but not good elsewhere. I think, in general, this camera was designed with the studio in mind.
Kiev 4 - back/base removed
To release the back/base there are two folding lugs to turn half a turn. Inside the camera is as you would expect a 35 mm camera to be. Until, that is, you look at the shutter. Instead of the rubberised cloth usual until the 1980s, it consists of brass slats which move vertically and are held on cloth ribbons. this works the same as a cloth shutter as distinct from the modern metal shutters. Speeds provided are impressive - up to 1/1250 seconds and down to 1/2 second. The speed range is the modern one of 1/125, 1/250, 1/500 etc.

Kiev 4 - detail of brass shutter
The lens supplied is the Jupiter-8M. This is a Soviet copy of the Carl Zeiss Sonnar lens. This lens has six elements in three groups. How well it performs remains to be seen. Someone has attempted to dismantle my lens (never a good sign) evidenced by the aperture adjustment ring being out of kilter. Hopefully, that is as far as they got - none of the internal black paint is scratched which his a good sign. Ro-orienting the aperture ring was simply done.
Jupiter-8M lens - front bezel
The aperture has nine blades which gives a good shape to the aperture. What is curiose is that the aperture blades are curved (see photo) producing a clearly less than circular disc. I will try to produce some booked shots with my test film to see if this makes much difference.
detail of lens showing curved aperture blades
The Jupiter 8 M is a 50 mm lens with a maximum aperture of f/2 and a minimum aperture of f/22 - quite a useable range. f/22 is about the limit in 35 mm photography before diffraction softening starts to be a nuisance. The aperture ring has click stops but can still be set between these values The finish on this lens is shiny chrome with a black lens bezel. - contrasting with the matt chrome on the camera body. Test film is developed and here are the results. I am quite impressed. Soviet execution of German design is as good as it always is. There are no light leaks - always a bugbear of old cameras, neither in the seals around the base/back nor in the sutler blinds - an advantage, I would think, of using brass rather than cloth. Exposure is even indicating that the shutter blinds are both moving smoothly. There is no lens flare - although these test pictures were mostly taken in rather overcast conditions. The rangefinder test (see below) shows both that the rangefinder is accurate at close distances and that the lens produces sharp images. The picture of the iron shutter shows the one draw back of a rangefinder camera (or any viewfinder camera, come to that). I had the shutter central in the viewfinder but it is distinctly off-set in the image - parallax problem. Some cameras adjust the viewfinder when focusing closer but not here. The pictures:

Mamiya made cameras both for themselves and for re-badging by other companies. This camera is re-badged by the USA company of Mansfield. It is badged as a Mansfield Eye-tronic but is actually a Mamiya EE Super Merit. This model was also available in the USA as a Honeywell Electric Eye 35 and in the UK as the Vulcan. The camera is well designed and well made as I would expect from the Japanese in 1962 (the year of this model's introduction, in September). That makes this camera 50 years old (give or take a year) - and it is in very good condition. It all functions as it should, the only real deterioration being the foam light seals - as is usual on Japanese cameras of any age, these are reduced to a sticky goo and I have partially replaced them. The seals I have replaced are the two ends: around the hinge and around the catch. The long seals top and bottom of the back look to be recessed enough not to cause any trouble - I shall see for sure when my test film is completed (12 exposures of Fomapan 200 Creative).

Front view - lens with a Petri UV filter in place
This camera is about the standard size and weight for a fixed-lens Japanese rangefinder camera of the period. it measures 130 x 60 x 80 mm and weighs xxxg. Of the three Japanese rangefinders I own, this is the most thoughtfully designed.
The top plate is spare. On the left is the rewind crank which is slightly proud of the top plate when not in use. In the centre is the accessory shoe - a cold shoe as it has no flash contacts. In front of then accessory shoe is stamped the name "Mansfield" - this would say "Mamiya" on a non-re-badged version or "Honeywell" or "Vulcan" for the other brands of re-badged Mamiyas. On the right of the top plate is the frame counter - this counts down to zero so needs to be set at the film length when you load the film. I don't usually bother with frame counters - I just keep using the camera until the increased tension in the film advance tells me the end has come. With this camera it is, if not essential, then very useful to set the frame counter as when the film is finished the film advance lever keeps moving with no change in tension. What this camera does is when the frame counter reaches zero the word "END" appears in the viewfinder. You can keep winding the film and pressing the shutter release but the film is not moving and you are repeatedly exposing the same last frame.
Top view
The front has no surprises. The viewfinder bezel is at the top. This is black plastic with a very worn (on my camera) chrome outline. The viewfinder is slightly to the left of the lens and the rangefinder window is slightly to the right (both as when using the camera).
The viewfinder has bright-lines and the display for the light meter. There are no parallax markings for close-ups as the viewfinder physically moves as you focus the lens. This is quite a sophisticated facility for a mid-range camera. The viewfinder also includes the word "END" when the frame counter reaches zero.
The rangefinder spot is yellow (as is usual) but is an undefined blob which makes using the rangefinder harder than it should be. Having said that, it does work in good light - test photos will tell me how well. Both the light meter and the rangefinder are coupled.
Inside
Below the viewfinder bezel is the shutter assembly. The shutter is made by Seikosha and is a leaf shutter. the camera offers a choice between automatic and manual exposure control. In auto, the required shutter speed is set and the diaphragm set to auto - the camera selecting the aperture. See the notes on the test film to see how well this works. If you want manual control of the exposure, you can set the aperture as well as the shutter speed. the light meter display in the viewfinder will tell you the required aperture for the set shutter speed (the only time you need to look at the light meter display) or you can use a hand-held light meter to gauge exposure (see below where I have tried all three methods on one picture).
back
On the bottom of the shutter housing is the selector for the film speed. this shows the camera's age as it goes as low a 10ASA/11DIN but only as high as 200ASA/24DIN. The lens itself is surrounded in common Japanese fashion with a circular selenium light sensor. This means it is always pointing the same way as the lens and gets covered by any filter used. In turn, this means that no exposure compensation is needed with filters - as good as you can get without TTL metering. Incidentally, selenium means that no battery is required for the light meter to work.
Underside of lens showing DIN/ASA selector
To the right of the shutter housing is the shutter release button. Personally, I do not like face mounted shutter releases but I have to admit that this one is fine in use. There is a screw socket for a cable release but this is on the top plate. On the opposite side of the shutter housing is a PC socket for flash. There is no means of synchronising the flash so I assume it is intended for FP bulbs or electronic flash.
The back of the camera is very plain - just the viewfinder eyepiece and the film advance lever. Inside, film attachment is very simple and is about the easiest I have ever come across. There is a generously wide slot with a prominent tang to fit into a sprocket hole. Most 35mm cameras have a shaft with top and bottom sprocket wheels. Not here. There is a single large sprocket wheel below the film gate. This does nothing with the back open making it easy to secure the film to the take-up spool - the film advance will keep moving the film without the user having to repeatedly press the shutter release. Once the back is shut, this sprocket wheel will only allow one frame to advance at a time.
Shutter set to shutter priority automatic exposure
The base of the camera is also bare - just the tripod boss (1/4 inch) and the rewind button.
Shutter set to manual exposure.
Test film results.
The results are good. In the pictures, the horizontal bars to be seen in the sky in some pictures are a scanning artefact due to the negatives being a bit thin (i.e. under-exposed). Overall, both focus and exposure are as they should be producing usable negatives. Although not all the negatives have scanned well, they would produce reasonable silver -prints.

This next photograph is a test of the rangefinder. I focussed on the nearest pale ball on top of the black steel fence. It is not quite in focus - focus being just a bit closer than it should be (look at the black top rail of the fence just this side of the pale ball).

This is what happens if you continue to take pictures after the film has ended. The camera does nothing to stop you (apart from displaying the word "END" in the viewfinder) and you end up with multiple exposures on one frame.
The last frame of test film - multiple exposure
These last three show the effects of 1) using automatic exposure, 2) manual exposure using the built-in meter and 3) manual exposure using a separate hand held meter. All three are exposed well enough to be usable with the automatic exposure perhaps being the best exposure. it is a bit surprising that using the built-in meter automatically differs from using the same meter manually, but the difference is there. This is possibly due the the camera being able to select in-between aperture values while with manual exposure you have to use one of the marked aperture values. The last exposure, using my trusty (and trusted) Ikophot meter is of more concern as it is clearly rather underexposed.

I recently made a decision to add a few rangefinder cameras to my collection. I have had a Minolta Uniomat for a few years and recently bought a Zorki 4. These two cameras represent the two lines of rangefinders that were available in the world of film.
The Zorki is from the line of interchangeable lens rangefinders that follow on from the Leica. Most of these are fairly straight copies of Leicas - all German patents were declared void after the end of WWII - with varying degrees of development.
The Uniomat is from the other - fixed lens - line. These fixed lens rangefinders are cheaper, though never cheap. Not having an interchangeable lens means they can - and do - have between-the-lens leaf shutters.
Petri 7s - front view [(C) John Margetts]
My collection of fixed lens rangefinders now numbers five (I am only including those with a coupled rangefinder) - Vitomatic II, Contessa LKE, Uniomat,Minister III and now this Petri 7s.
This Petri 7s is exactly the same size and shape as the Minister III - I could almost suspect they used a common casting for the body. The weight is not too different, either - 632g with a film loaded.
lens: Petri
focal length: 45 mm
apertures: f2.8 to f16
focus range: 0.8 m (2.6 ft)
lens fitting: fixed
shutter: Petri MVE
speeds: 1 s to 1/500 s
flash: PC socket
film size: 35mm
The top plate of the Petri 7s is uncluttered. On the left is the rewind crank. This is the now standard fold-out crank which I personally find hard to use. The crank pulls up to allow for the insertion/removal of the film cassette.
Petri 7s - top plate [(C) John Margetts]
Just left of centre is the accessory shoe. By the time this camera was designed (1963) this was usually for a flash gun. It is a cold-shoe - accessory shoe contacts had to wait a further decade to become standard. To the right of the accessory shoe is the light meter window. This is fairly small - the actual window is 5 mm diameter - and incorporates a lens to make seeing the needle and mark possible.
Next along is the shutter release button. This is fairly large - no bad thing - and is threaded for a standard cable release. On the rear right-hand corner of the top plate is the frame counter. This is also a bit on the small size but still usable.
The front of the camera is dominated by the shutter housing. This is fairly large for a fixed-lens camera - the size is necessary because of the light meter sensor around the lens (as in the Yashica Minister III).
Petri 7s shutter housing [(C) John Margetts]
The lens is a 45 mm f2.8 lens. It has no name on it apart from Petri. A green 'C' signifies that it is a coated lens - normal for the time - but does not tell us if it is multi-coated or single coated. As far as I can find out, it is a Tessar copy - four elements in three groups for the technical minded.

The shutter housing has several controls on it. There are the expected control rings - focus, aperture and shutter speed - a flash synchronisation selector (X or M), a delay action lever, film speed selector and a PC connector for the flash. The shutter housing carries the name 'Petri MVE'. The shutter itself is a leaf shutter which means it is quiet in use - excellent for street work.
Above the shutter housing is an elongated window containing the rangefinder window and the viewfinder window. The viewfinder is a reverse Galilean finder (like looking through a telescope the wrong way) and the image is coloured a pale green. On the right-hand end of the front, just below the shutter release, is another window but one that does not seem to have any purpose - perhaps for a facility intended but not implemented. The viewfinder has bright lines with parallax markings. It also has a repeat of the light meter needle. This is much easier to see than the one on the top plate. It is not, however, easier to use as it is very hard to distinguish between the shutter speed and aperture rings by feel.
Petri 7s spurious window [(C) John Margetts]
The rear of the camera is plain. There is the eyepiece of the viewfinder and the film advance lever. The base of the camera is also plain. It contains a tripod boss in line with the centre of the lens (1/4" Whitworth is what I usually say, but it could well be modern enough to be 1/4" UNC. The ISO standard for tripod threads is UNC rather than Whitworth but there is not much difference between the two and Class 1A threads (to be tightened by hand) are sloppy enough to be interchangeable between Whitworth and UNC), and a recessed button to allow for rewinding the film.
Petri 7s rear view [(C) John Margetts]
Using the camera is quite easy. Setting the film speed for the light meter is a matter of rotating the black tab in front of the shutter speed ring - this is on the lower right of the shutter housing. The selected film speed appears in a small window in the shutter speed ring to the left of the fastest shutter speed. This is in both DIN and ASA and goes from 11 DIN/10 ASA to 24 DIN/200 ASA. (ASA is broadly but not technically the same as ISO) This seems a bit of a slow range by today's standards but when the camera was made, it would have covered all the films likely to be used.
To set the exposure, you can either set the required shutter speed and then rotate the aperture ring until the meter needle is centred, or set the required aperture and adjust the shutter speed ring, again until the needle is centred. The meter is a selenium meter which means it does not need batteries. These can deteriorate if left exposed to light for many years but this one is still fine (actually, I have never come across a selenium meter that was not fine - I think the deterioration thing is mostly theoretical rather than real-world).

The focus ring has a large knob on the left-hand side which makes focussing with the left hand easy. There are two options for focus - scale focus or rangefinder. For scale focus, there is a big drawback in that there is no depth of field scale which makes my usual hyperfocal method impossible. The focus scale is in both feet and metres.
Using the rangefinder is not as easy as it could be. Petri have tried to make the rangefinder clear by colouring the viewfinder field a pale green and the rangefinder spot yellow. In my camera, the rangefinder spot is rather faint. In good light it does work, though, and it is quick to focus if you have suitable verticals in the frame.
The shutter release works easily without needing undue pressure but without being too much of a hair-trigger. The film advance moves about xx degrees and makes a very definite 'clunk' as it cocks the shutter.
The only other thing worth noting is that there are strap lugs at either end so I can carry the camera on a strap around my neck without needing to use the ever-ready case.
Test pictures.
I am testing this camera with Fomapan 200 Creative film - it is also a test of the film, to some extent as I have never used it before. I have a 17 metre roll of film and can cut off the amount I need - I am using a 12 exposure length for this test. This should save me quite a bit of money compared to buying colour film and paying to have it developed. I should have developed the film in the next few days and will post the results here when I have done so.
27/10/14
As well as testing the camera and film, I am also testing my developing of the film - it is basically developed OK but I can tweak it somewhat in the future to improve contrast. There are some horizontal lines visible - these are scanning artefacts due to the emulsion being a bit on the thin side.

This is a rangefinder camera from Yashica that is pretty standard for its time. It is almost exactly the same size as Zeiss Ikon's Contessa LKE of the same period and looks very similar as well. It is slightly larger than Voigtlander's Vitomatic II which is slightly earlier.
lens: Yashinon-DX
focal length: 45 mm
apertures: f2.8 to f22
focus range: 0.8 m (2.6 ft)
lens fitting: fixed
shutter: Citizen
speeds: 1 s to 1/500 s
flash: PC socket
film size: 35mm
The camera is quite heavy - 656g including a 24 exposure cassette of film. This weight is going to tell at the end of a busy day photographing. It is 135 mm long and 85 mm high. The body is 35 mm thick which increases to 85 mm when the lens is included.

There are not many controls on this camera - it is entirely manual. On the top plate, starting on the left, is the rewind crank. This also pulls up to release the cassette for loading/unloading. Next to this is the accessory shoe. In flash terms, this is a cold shoe. next to this is the meter dial. This has two components: ASA setting and meter read-out. ASA can be set between 10 and 400 ASA (new style). Behind this is the read-out for the meter. This gives you EV numbers between 4 and 18. In use, you choose the EV number the needle is pointing to and transfer this number to the outer most ring on the shutter housing. You are quite at liberty to ignore this if you want to - if you are using a hand-held meter, perhaps - or using the flash.
Next in line is the shutter release button, which is towards the front of the top plate. This is a small (by modern standards) chrome plated button, threaded for a standard cable release. Beside this is the film advance lever. Right on the right-hand end of the top plate is the frame counter. This is automatically reset when you open the back and counts up from 1.
The front of the camera has the viewfinder and rangefinder windows and the shutter housing with lens. The viewfinder is quite large and bright and has bright-line frame lines. In the centre of the viewfinder image is the yellow rangefinder spot. This is plenty large enough without getting in the way and is nice and bright. The rangefinder is coupled to the lens.
The shutter is made by Citizen - no model name is given - and it is a leaf shutter. The shutter housing is fairly large and central. Partly, it looks large compared to Compur and Prontor shutters of the period as it is straight sided rather than stepped. There are three adjustment rings on the housing. The inner most, marked in green, is the focussing ring. This focusses from 0.8 metres to infinity and is marked in both metres and feet. Strangely, there is no pointer for this scale and the pointer position (where the pointer would be if there was one) is well to the right of centre. I suspect the designer thought there was no need for a pointer as the user is intended to use the rangefinder but I would be more comfortable if there was one.
The outer most adjustment ring, marked in red, is where you set the EV numbers from the light meter. Even though the meter only offers numbers from 4 and higher, the ring is marked for 2. Setting this ring gives the user a range of both shutter speeds and apertures. Once the EV number is set, you can rotate the middle adjustment ring - the shutter speed ring - to change the shutter speed. Doing so also alters the aperture so that the required exposure is maintained. There is no direct method for adjusting the aperture, but there is a small window immediately behind the shutter speed ring showing the set aperture. If you want a particular aperture (which I usually will) you can alter the shutter speed until the desired aperture is displayed in the window.
Minister III - rear view ((C) John Margetts)
On the base of the shutter housing is a small lever which sets the delay timer. Although we are always told not to use this on an old camera, I can report that it works very well on this particular old camera.
In the front of the shutter housing, around the lens, is the light meter sensor. This is a selenium sensor and so needs no battery - there is no problem with this camera of having to find a replacement for an obsolete mercury battery. Many 'experts' will tell you that old selenium meters are too unreliable to be worth using. This is based on the fact that the light sensitive surface deteriorates with time and then gives low readings. While this is true, if the meter has been kept in the dark except when being used the deterioration over 60-odd years is so slight as to present no problems. I have many selenium meters that are 60-odd years old and they all give accurate readings and I shall continue to use and trust them. I doubt those 'expert' who decry using old selenium meter have actually tried using them.
The advantage of having the light meter sensor around the lens is two fold. Firstly, it is always pointing in the same direction as the lens and secondly, if a filter is used, it fits over the sensor and no adjustment of the meter reading is required.
The lens is a Yashinon-DX lens (I do not know the significance of the 'DX'). This lens has five elements in four groups and is reputed to give very good results. The focal length is 45 mm so the angle of view is very close to the human eye and accordingly will give natural looking results. The largest aperture is f2.8 which might not seems to be particularly fast, but, to be honest, I never shoot much wider than f8 so I just do not care that the lens does not go to f2 or f1.8
This camera has a PC (Prontor-Compur) connector for the flash and this is, idiosyncratically, place on the left-hand end of the camera.
The base plate of the camera has the usual tripod boss - this is the 1/4 inch Whitworth thread - and it is placed centrally behind the lens which means the camera will be stable when on a tripod. Also on the base is a recessed button to free the internals for film rewind and, at the opposite end, a recessed button for unlocking the back. I find this hard to use - you need to slide it to one side and then press it in. Perhaps with time I will find it natural, but not yet.

I have now completed my test film and I am quite impressed. The camera is easy to use - the light meter works well as does the viewfinder. I had some flare when shooting into the sun but I did not use a lens hood. Generally, the lens has good contrast and colour rendition.
I took the picture of the reed flower to test the lens at maximum aperture. The flower is nicely sharp and the background not sharp - as I would want it. These were all taken in October, so not a lot of sun about.
