Exa 500

This is my fourth Ihagee camera and my third Exa.  The original Exa was a cut-down low-cost version of the Exakta and then the Exa line developed in its own right.

Exa 500 - front view

The Exa 500 is the end of the line for Exa cameras  and was developed after Ihagee was subsumed into VEB Pentacon, the state camera manufacturer.  The lineage from the Exakta is apparent in the shape.  This camera still has the rhomboidal shape introduced with the original 127 format Exakta in 1933.  It also still has the shutter release on the left, although the film advance is now on the right.  Another change is the fixed pentaprism viewfinder, so I cannot use the delightful waist level finder with this camera.

The immediate predecessor of this camera was the Exa II.  The body of the Exa IIa and this Exa 500 are identical although there are some internal differences.

The Exa 500 has a vertical cloth focal plane shutter which travels from bottom to top.  This shutter provides speeds from 1/2 to 1/500 seconds plus B.  This means it is twice as fast as the Exa II.  There are two flash settings: 1/60 for electronic flash and 1/15 for flash bulbs. This camera follows the Exa standard and flash synch is achieved by aligning a dot on the speed dial with either a zigzag icon or a bulb icon.  On the front of the body is a single PC connector.

This camera also has a shutter lock beside the viewfinder - cover the red dot to shoot, uncover to store the camera.  The only other real change between the Exa II and the Exa 500 is that the Exa 500 has an instant return mirror so the viewfinder does not go blank when you fire a shot.

Like other Exakta/Exa cameras, the film take-up spool is removable and can be replaced with an empty film cassette.  Doing this obviates the need to rewind the film but it does cost you one frame of film.  There is no internal knife to cut the film like the Exaktas have so this must be done after opening the back.  The only real advantage of this is the possibility of developing half a roll of film but I cannot imaging that many people have ever bothered.

The film advance is on the right as is normal in non-Ihagee cameras.  It has quite a short stroke of just over 90 degrees (compared to the Exakta Varex II where the advance travels about 300 degrees).

The back of these cameras come away from the camera body in one piece with the base.  This is supposed to make it easier to load film but I find this method harder.

Exa cameras were supplied with a variety of lenses depending on how much the customer wanted to pay.  This camera has a Meyer-Optik Domiplan. This is a triplet design so not as good as the Tessar option, but the Domiplan performs well enough when stopped down.  The lens is a semi-automatic lens - the diaphragm closes when the shutter release is pressed but stays open for composition and focussing.

The Domiplan achieves this automation by a hinged lug that protrudes over the shutter release - the photographer presses this lug which in turn presses the shutter release.

This mechanism in the Domiplan lens has a weak link that is prone to seizing but this particular lens performs OK.  My other Domiplan lens needed the mechanism cleaning with naphtha before it would work satisfactorily.

This camera would also work with my Exa fit Carl Zeiss Jena Tessar (we need to specify Carl Zeiss Jena in contradiction to Carl Zeiss Opton, the new (at the time) Carl Zeiss operation in West Germany.  East German Carl Zeiss Jena lenses are generally better than Carl Zeiss Opton lenses).

In use, this camera is much as you would expect.  The shutter speed selector is rather loose and I was not sure I was actually selecting any speed, but I tried exposures at various shutter speeds and they have all come out well exposed so the shutter speed selector must be doing its job.

There is a red flag in the viewfinder to tell you that you need to advance the film before taking the next shot.  In previous Exa cameras this was not necessary as the mirror would only return to the viewing position when you had wound on.  In this model, the mirror is an instant return mirror and it would seem that the makers thought users might get confused with such sophistication, hence the red flag.

The camera is light-proof (not a given with old cameras) and the shutter is moving smoothly.

Here are some sample photographs from my test film:

Exa IIa

Exa IIA front view

lens: Meyer Domiplan

focal length:  50mm

apertures: 2.8 to 22 in 1/2 stops

focus range: 0.75m to infinity

lens fitting: Exakta bayonet

shutter: vertical cloth focal plane

speeds: 2, 4, 8, 30, 60, 125, 250

flash: bulb or electronic

film size: 35 mm

Externally, this is very like the Exa Ia and exactly like the Exa 500; it has the usual Exakta trapezoidal shape.  The layout on the front fascia is the same - shutter release on the left at the top, PC connector on the right at the top.  The lens fitting is the standard Exakta double bayonet (an internal bayonet for short focal length lenses and a larger external bayonet for longer focal length lenses).

A PDF manual is available on my Google Drive

There are differences, however.  The IIa has a fixed pentaprism and eye-level viewfinder with a Fresnal focussing screen with a split-image centre.  The shutter is now a vertically running cloth focal plane shutter rather than the strange mirror shutter of the Ia.  Along with the more standard shutter comes a larger range of shutter speeds  - eight speeds with the fastest  now being 1/250 seconds.

The removable back/base is exactly the same as is the shutter lock on the left of the viewfinder.   Another change is that the rewind knob is now a fold-out crank.

With a vertical focal plane shutter, it should have been possible to increase the flash synchronisation  speeds but they are rather slow - 1/15 for bulbs or 1/30 for electronic flash.  The fact that bulb flash needs a slowest synch speed suggests that the only synch available is as the first shutter curtain ends its travel, bulb synch relying on the shutter being still fully open when the flash bulb reaches full intensity.

The Exa IIa came with a Meyer Domiplan lens rather than the Carl Zeiss Tessar that was standard with the Exa Ia.  I have yet to see the results from this lens but it has the reputation of delivering good results when stopped down.

This lens, like the Tessar, automatically stops down the aperture when the shutter release is pressed.  Exa lenses manage this by means of a lug on the lens barrel that covers the shutter release on the camera body.  The shutter is activated by pressing this lug which in turn presses the shutter release.

On the Domiplan lens, this lug is hinged and so presses the shutter release through an arc.  Because the release is not pressed straight in it can cause internal damage to the release mechanism.  This is made worse if the lug does not exactly line up with the shutter release so that it presses on one side of the release button.

shutter release lugs - Domiplan on left, Tessar on right

There is a further fault with the Domiplan.  As mentioned above, the release lug is hinged and this hinge dries out with time.  When the lubricant has dried out, the lug will not always return to its rest position after a photograph is taken.  This means that the aperture does not re-open to f2.8, leaving the viewfinder dark.  In use, this is easily remedied by flicking the lug with the shooting finger but it is annoying, nonetheless.  I have applied clock oil to this hinge and it is showing signs of freeing itself up.

4 February 2013:

Having run a test film through this camera, it is difficult to assess the camera's performance.  All the pictures ended up bright green.  This could not have  been down to the camera - it is an SLR and I would have seen the green through the viewfinder.

There are three possible causes for this green - defective development, defective film or defective scanning.  The staff in the lab assure me that mine is the only film to have come out green and so they do not think it was their development.

Defective scanning is a possibility but I would think it to be an automated process and if they have not changed any settings then the scanning process should not produce any colour cast.

The third possibility is a defective film.  The film I used was Agfaphoto Vista + 200 ISO, made under contract in Japan by, I think, Fuji-film.  Reputable makes of film should be reliable but in any factory process it is possible for the occasional item to escape the quality assurance system.

I am thinking that the reason for the green cast in my test film is the middle one - a defective scan - looking at the negatives, there is evidence of all three colours on the perforated rebate of the film (these are the frame numbers in magenta (the negative of green) and test lines in red and green (the negatives of cyan and yellow)) so it looks like at least part of the film has the requisite colour layers in the emulsion and the development has developed these correctly.  When I have time, I will scan the film myself to check the scan quality.

In addition to the green colour there are other problems which are definitely down to the camera.  At the bottom of each picture is a very over-exposed strip - this equates to the top of the film in the camera.  As the shutter travels vertically from bottom to top, this is most likely caused by the second shutter curtain hesitating slightly at the end of its travel.  This might cure itself with use which is quite common with 'stiff' mechanisms in old cameras.  I also need to be aware that I used this camera in sub-zero temperatures.  The lubricant in the shutter will be thicker at these temperatures and the shutter might well work better in warmer weather.

In general, looking at the negatives, the film has been exposed appropriately with good, but not excessive image density.

Some of the negatives are blank but this is down to operator error.  The shutter release is in the 'wrong' place.  Years of practise have taught me to be careful with the placing of my right hand when holding the camera.  With Exas I need to be careful with the placing of my left hand instead.  I also need to learn to use the shutter lock when not actually shooting.

This is my second Exa camera and my third roll of film on Exas.  That is enough to know that I like using Exa cameras with their various idiosyncrasies.  See further down for well exposed pictures from my second roll of film.

 I now have a test film with correct colours.  Nothing to complain about there,

Ihagee Exa 1a

Exa 1a, front view

This is a German SLR camera made by Ihagee of Dresden, Germany.  Ihagee (short for Industrie- und Handelsgesellschaft) was started in 1912 by a Dutchman in Germany.  Until the mid-1930s, Ihagee made more or less standard folding film cameras.  In 1933 they introduced the first Exakta, an SLR which used 127 film (the roll film equivalent of 35mm).  Using 127 film enabled them to make very small cameras.  In 1936 they introduced the Kine Exakta, an SLR which used motion picture (35mm) film (hence Kine).  The Exa range was a smaller and simpler version of the Exakta.

lens: Carl Zeiss Tessar
focal length: 50mm
apertures: 2.8 to 22
focus range: 0.5 m to infinity
lens fitting: Exakta bayonet
shutter: Exakta mirror shutter
speeds: 1/30, 1/60, 1/125, 1/175
flash: PC connector, bulb or electronic synch
film size:  35 mm

The Exa 1a was introduced in 1964 and was produced until 1977.  In some markets it was called Elbaflex 175, Exakta 100 or VX 100. The Exa II range were made concurrently with the EXA I range.  The camera can be dated by the origin engraved on the top plate.  This ranged from 'Ihagee Dresden' to 'aus Dresden', the Pentacon tower, to 'Dresden' to no engraving.  Mine has 'aus Dresden'.  The back of the camera has 'MADE IN GDR' stamped in the leatherette as well as '1' in a triangle.  The '1' in a triangle is a quality mark indicating the finished product is of the first quality.   (There were briefly two Ihagees - the original Dresden Ihagee in East Germany and a new Ihagee formed by the pre-war owner in West Germany - this camera was made in East Germany.)

This is an idiosyncratic  camera in some ways.  The camera is rather wide front to back (150 mm) in the middle and narrows at each end with the typical Exakta trapezoidal shape.  The shutter release is on the left side on the front and presses in rather than down.  The shutter release continues through a lug on the lens which shuts down the iris diaphragm just before the shutter is released.  The shutter itself is idiosyncratic  - it is neither an leaf shutter in the lens nor a focal plane shutter next to the film.  Rather, the mirror acts as the shutter in a way that I do not quite understand - but see here for details.  The viewfinder and pentaprism are removable, the focussing screen replaceable and the whole thing can be replaced with a waist-level finder.

Ihagee did not make lenses so the Exa 1a was supplied with various lenses. My Exa 1a has a Carl Zeiss Jena Tessar (as opposed to a Carl Zeiss Opton Tessar from West Germany) dating from 1970.  It is a f2.8 50mm lens with an Ihagee bayonet fitting.  Any Exakta or Exa lens should fit although I am told that long lenses (i.e. 100 mm) will cause vignetting.  There is an idiosyncratic aspect to the Ihagee bayonet - it is, in fact, two bayonets - one inside the mouth (for most lenses) and one outside the mouth for larger lenses.  The lens focusses from 0.5 m to infinity and has apertures from f2.8 to f22 available in 1/2 stop click positions.  As mentioned above, the shutter release acts through a lug on the lens and stops the lens down as it releases the shutter.

Shutter speeds are 1/30, 1/60, 1/125 and 1/175 (+ B).  Because of the way the mirror is used as the shutter, faster shutter speeds are not possible.  On the shutter speed dial there is a red dot for synchronising the shutter  for flash.  For electronic flash this is 1/60 seconds and for bulb flash it is 1/30 seconds but the actual setting is against a lightning icon for electronic flash and against a bulb icon for bulb flash.  There is a lever to the left of the viewfinder that will lock the shutter to prevent accidental exposures - a feature I wish more cameras would have.

There is no accessory shoe for a flash gun but grooves around the viewfinder eyepiece suggest that an optional shoe might have been available.  This does not matter to me - I never use flash - except I usually put a film type reminder in the accessory shoe to remind me that there is a film loaded and which type it is.

The film advance lever is rather small but moves the film on with one movement.  In the centre of the film advance is the frame counter   A wheel under the the film advance sets a reminder for the type of film in use - DIN, ASA, negative or reversal.

The viewfinder gives a 1:1 view of the scene and with the focussing screen supplied is clear and bright.  As is usual with a new old camera, near the end of my test film I am beginning to use the camera automatically.  I also have a waist-level viewfinder for this camera.

Waist-level finder, closed

The viewfinders snap out of position fairly easily when you want to change them (but are firmly held in place normally going on) and both the finder and the focussing screen can be replaced.  Both my focussing screens are plain ground glass.

Waist-level finder, open

 It is fairly easy to use from waist level but critical focussing is difficult from that distance.  Using zone focussing, this viewfinder is certainly ok for composing the shot and is much more discrete than holding the camera to your eye.  For critical focussing, there is a built-in magnifier but to use this, you need to raise the camera to face level and you then lose the advantage of having a waist-level finder - but still better than changing finders mid session, I would think.

I think this camera will be a user if there are no shutter problems or light leaks.

15-12-2012:  

I have just bought a 2X teleconverter for this camera.  It cost me £7.00 including postage.  It was described on Ebay as a Pentax teleconverter and only attracted one bid - mine!  I could easily see it was an Exakta fit converter by the offset shutter release on the lens body - a feature that I have only ever seen on an Exakta (or Exa) camera lens.  It is excellent condition - there are no moving parts to go wrong - and just needed a good clean.

2X teleconverter, Exakta fit

 Unfortunately, I cleaned it with ROR lens cleaner and sprayed directly onto the glass instead of on to a tissue and I now have condensation between the lens elements.  I am thinking that if the moisture got in that easily, it will dry out again fairly easily. When it has dried out, I will try it and post the results here.

I now have my test film developed so here are some of the test pictures.  They disclose a slight fault as many of the pictures have a dark wedged shaped line at the top of the picture.  It is present on the negatives so is not down to the scanning.  I suspect the shutter is slightly out of line.  Bearing in mind that this camera has lain unused for many years before I bought it, I am hoping that the fault will rectify itself with the camera being used.

I now have finished my second film on this camera and the shutter is working fine.  Those black wedges have gone from the tops of the frames entirely.  Many old cameras that are a bit 'hesitant' just need to be used for a couple of films to be alright.
