Ihagee West - Exakta TL500

I do not intend to repeat the history of Ihagee here, suffice it to say that during the 1950s, 60s and 70s there were two Ihagee companies - the original Ihagee in Dresden that became absorbed into VEB Pentacon and a newer Ihagee West started by the original owner of the Dresden Ihagee (Johan Steenbergen) after he was unable to return to Dresden.  This camera is from Ihagee West rather than Ihagee Dresden. I say 'from' Ihagee West and not 'by' Ihagee West as they neither designed nor made this camera which bears their name.

Ihagee West Exakta TL500
In fact, this camera was designed and made by the Japanese company Petri. I am not saying that is a bad thing - Petri made some fine cameras and this camera is a fine camera - but it is not a German camera and does not carry any of the well-loved Exakta design concepts. The legend on the front of the camera says 'Exakta TL500' but in fact it is a re-badged Petri FT - the only clue to this is the stamp on the base saying 'Made in Japan'.

This camera is fairly heavy - it weighs 682 g with no lens - and measures 145 by 95 by 50 mm. This camera was made (or rather, marketed) in 1976 only (I have been unable to find much information about this camera or, indeed, Ihagee West other than neither maker nor camera were very successful). The layout is pretty much standard for the time.

Exakta TL500
Most controls are on the top plate. On the far left is the rewind crank. (the usual Exakta system of film cassette on the right and take-up spool on the left has not been maintained) and is the now usual small fold-out crank. This lifts to release the film cassette inside.

Next to this is the the film speed selector - the main scale is ASA and is printed in white, there is also a DIN scale printed in red. This selector moves in 1/3 stop click-stops - i.e. one degree DIN. The range is from 25 ASA to 1600 ASA (ASA being effectively the same as ISO). In the middle is the bump of the pentaprism with an accessory shoe on top. This has a central contact for flash and so is a hot shoe.

To the right of the pentaprism is the shutter speed selector. This goes from one second to 1/500 seconds in the usual sequence (the maximum speed of 1/500 gives the camera its name - its sister camera, the TL1000, had a top speed of 1/1000). Flash synch is marked with a red cross as 1/60. At the date of this camera, the makers will have assumed electronic flash.

On the right hand end of the top plate is the film advance lever. This is tipped in black plastic and moves through 180 degrees to wind on one frame.  Between the shutter speed selector and the film advance lever is a window for the frame counter. This resets to -2 (indicated by S) when the back is opened. This counter counts up from zero.

The front of the top plate, apart from the name, has nothing but the battery compartment. This holds a PX625A alkaline battery (still readily available). On the end of the top plate, on the left, is a PC connector for off-camera flash. Both the battery compartment and the PC socket are in unusual places. In fact, this is the first time I have seen a battery compartment anywhere but on the base plate. Unusual it might be, there is nothing wrong with it.  On the front of the camera there is nothing apart from the lens. There is no shutter delay lever on this camera. The lens mount has a standard M42 thread - Ihagee abandoned their Exakta bayonet mount right at the time that other camera makers were abandoning M42 threads. On the plus side, there were (and still are) a great many lenses available in M42 mount. Replacing the threaded mounting ring with an Exakta bayonet mounting ring would have been easy and cheap but it may well have cost more to do so while maintaining the correct lens-to-film distance. Regardless, Ihagee West went with Petri's M42 mount.

At the bottom of the lens mount is the TTL exposure meter switch. This is a stop-down system - pressing the switch stops the iris diaphragm down and switches on the electronics. To use, first you select your shutter speed, then press the meter switch and, while holding down the switch, turn the aperture ring until the meter needle in the viewfinder coincides with the white circle. It is possible to use this meter by setting the aperture and adjusting the shutter speed to match the needle-white ring but this is very awkward to do.  As the aperture stops-down to take the light reading, the viewfinder becomes very dark and it can be difficult to see the meter needle. 

At this point, I should offer a caveat to any new user of an Exakta TL500 (or TL1000). The exposure meter is automatically switched off by taking a picture. If you cannot get the meter to respond, wind-on the film. This is a good system as leaving the camera without winding on the film will prevent the battery from running down.

The base plate is uncluttered, having the rewind button and a 1/4 inch Whitworth (i.e. standard) tripod boss.  The catch for the back is on the left end and is pulled up to release the back.

Inside is as we would expect. On the left is the space for the film cassette, in the middle is the image window (24x36 mm) and on the right is the toothed sprocket that allows the film to be advanced a set number of sprocket holes. Right on the right is the take-up spool. This rotates in the opposite direction to the film advance lever. The lever moves counter-clockwise while the take-up spool rotates clockwise. This means that the film is stored emulsion side outwards..

The edges of the back have black light-seal foam to prevent stray light getting in the join and fogging the film. This became normal in the 1960s but has the disadvantage that the foam eventually goes gooey and ceases to act as a light seal. I suspect that the designers of this camera would be surprised that their creation was still in use after forty years. I would imagine that cameras of the time had an expected life well within the useful life of the foam. Replacing light seal foam is both easy and cheap. I have a sheet of suitable self-adhesive foam bought on Ebay which only cost two or three pounds. The old foam can be removed with a cotton bud soaked in naptha (aka lighter fuel) and the new foam cut into suitable sized strips with scissors and then stuck in place.

I don't know what lens this camera came with when new but my TL500 came with an Auto Optomax. This lens is a 28mm lens so it is unlikely to be the original lens. Actually, this lens (which is in very good condition) makes a useful addition to my (small) collection of M42 lenses (this collection consists of a Helios-44 manual lens, Helios-44M auto lens, Vivitar 2x converter and this Optomax lens).

In use:

I had a spare half hour this morning and replaced the gooey light seals with new foam.  The camera should be good to go, so I have loaded it with Agfaphoto Vista + 200 ISO film (£1.00 per cassette from Poundland) and spent the morning taking photos of Lincoln. This camera came with no lens. I have been using my Soviet Helios-44M lens that came with my Asahi Spotmatic SP1000.  Tomorrow I am going to use my Optomax 28mm lens to finish off the roll of film.  Any M42 screw threaded lens will fit.

The first thing I have noticed using this camera is the weight. Over the last few weeks I have been using my Pentax ME Super and Olympus OM 10 - both of which are about as small as a film SLR can get and both are very light.

Not being made by Ihagee, all the controls are in the right place - i.e. both shutter release and film advance are on the right which makes using this camera fairly intuitive to use.

The camera is designed to use automatic lenses - which I am doing - but will still work with manual lenses (by 'automatic' I am referring to the diaphragm not the focusing).

To set the exposure, I need to choose a shutter speed, press the meter lever at the right side of teh lens mount base and while doing so rotate the aperture ring until the needle in the viewfinder is in the centre of the ring.  this sounds harder and more complicated than it is. The only problem I am having with this is finding the aperture ring by feel - this is not an issue with the camera, it is just that I am used to the aperture ring being on the outer edge of the lens barrel. 

The shutter/mirror action is quite good - not a lot of jar.

All in all, I am quite enjoying using this camera. there is one problem which is to do with the camera/lens combination. Focused on infinity, everything is fine. Focused on 0.6m. everything is fine. But if I focus on the hyperfocal distance (6m @ f11) the mirror will not return after the shot. Nor will the lens unscrew. To return the mirror I am having to re-focus to infinity, wind on the film and fire the shutter.  This has resulted in several wasted frames.  [EDIT: this happened over the first few frames of the first film. At exposure 16 it is no longer happening.]

When the film has been developed, I will post a selection of the test pictures.

Here are a selection of pictures from my test film.  I am quite impressed.  All are exposed well so no problems with the exposure meter.  Exposure is even so the shutter blinds are moving smoothly.

Praktica MTL5B

This is my second Praktica (the other one being a Praktica TL3).  It is in good condition - including the battery compartment - and came with a number of extras.  These were a Vivitar 2x teleconverter (M42 thread so usable with my other M42 thread cameras), a Praktica flash, a Leningrad light meter and a cheap but quite good carry bag.

Praktica MTL 5B


lens:  Helios-44M
focal length:   58 mm
apertures:  2 - 16
focus range:  0.55m to infinity
lens fitting:  M42 thread
shutter:  metal focal plane
speeds:  1, 1/2, 1/4, 1/8, 1/16, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000
flash:  Hot shoe, no PC connector
film size: 35 mm

This is a fairly standard late 70s to mid-80s SLR camera. My first Praktica - I also have a TL3It is squarish and heavy with minimal use of plastics.  It is 150mm by 95mm by 55mm, not counting the lens.  The controls are standard for the time and where you would expect to find them.  The film advance is on the top right of the camera and is a lever which moves about a quarter of a turn.  At this late date, advancing the film also cocks the shutter.  Next to the film advance is the combined shutter speed selector and film speed setting control.  Shutter speeds are noted above and are all any photographer could realistically want.  Film speed can be set from 12 DIN/12 ASA to 33 DIN/1600 ASA.  The setting can be changed in one DIN increments (one third of a stop).

The camera came with a Soviet Helios-44M lens which is not original.  The Helios-44 lenses have a very good reputation - they are good copies of the Carl Zeiss Biotar lens - and this one is in very good, clean condition.  It is an automatic version of the lens - I also have a manual Helios-44 lens which came with my Zenit E - with a switch  to change between manual diaphragm and automatic diaphragm.  The aperture can be changed in half stops which is an improvement on my other Helios-44 lens.

The shutter release is an angled button on the right face of the camera.  My finger falls fairly naturally on this and it is comfortable to use.  Right by this button is a plastic lever which actuates the TTL metering system.  In use, you put your finger on the shutter release and instead of pushing down, you push towards yourself.  The diaphragm closes and the needle in the right side of the viewfinder moves.  You then adjust either the shutter speed or aperture to get the needle lined up with the notch in the middle (this is basically a match-needle type of meter).  It is designed as a shutter priority system, the idea being that you set the shutter speed with the camera away from your eye and then move the camera to eye level and adjust the aperture ring with your left hand while pressing the meter lever with your right hand.  Used this way, it is fairly easy to use.

If, like me, you prefer aperture priority metering, you need to set the aperture first and then adjust the shutter speed while looking through the viewfinder.  It is just about possible to do this but it is very awkward to do.  I am finding myself moving the camera down to adjust the shutter speed which makes the whole operation slower and less fluid.  The meter is powered by a 1.33V button battery.  Originally, this would have been a mercury cell which is now not available.  I am using a same sized silver button of 1.5V which will cause a slight mis-reading of the meter but of less than a stop so this will not be a problem with negative film.  With reversal (slide) film this might be a problem.

Focusing this camera is a delight.  The focusing screen carries the usual plain ground glass screen with a micro-prism circle and a split-image centre.  However, the split-image part on this camera is diagonal. With a standard horizontal split-image centre, it is necessary to find a strong vertical to focus on.  With this camera either a strong vertical or a strong horizontal will work as will a strong diagonal.  When I was using this camera to photograph a bush earlier today, there were no verticals, horizontals or diagonals I could focus on. I used the micro-prism circle which also worked well.  For those who have never used a micro-prism focusing screen, what you do is focus until the micro-prisms disappear.  The further from focus you are, the more prominent the micro-prisms are.  Once you can not make out the micro-prisms (or until they are as indistinct as you can make them) the image is in focus.

Below the shutter release there is a self-timer (Vorlaufwerk in German) which works by turning the small lever through 180 degrees and then pressing the centre button to actuate the shutter instead on using the shutter release button.  This does work on my camera but not well.  It is very hesitant and stops for significant times but the mechanism is clockwork and has probably not been used for the thirty years since the camera was new.

The left side of the camera is bare apart from the rewind crank.  This is the normal small folding crank  that became usual during the 1960s.  It is released by pressing a button on the base of the camera.

The other external features are a frame counter beside the film advance lever which is reset by opening the back of the camera.  This counts up from one.  I prefer the Voigtlander system from the 1950s where the frame counter counted down to tell you how many frames are left but this did not become the industry standard.  There is also an accessory shoe which is a hot shoe in flash terms.  There is no PC connector (these had become passé by the time this camera was made) so flash must by on-camera flash or the photographer must buy a third-party flash attachment to allow studio flash.  The tripod boss is not on the base plate but moved forward onto the underneath of the lens mount.  This will give better balance when using longer lenses and is something I have not seen on more upmarket cameras although it makes a lot of sense.

The outside of the camera is 'silver' plastic top and bottom plate and a padded leatherette which is very nice to hold.  This is a big improvement on the standard leatherette on my Praktica TL3.

Inside is mostly standard film SLR layout.  The shutter is a metal vertical focal plane shutter.  Superficially, this is the same as on my Canon SLRs with several horizontal metal strips.  However, the fixing does not look as sophisticated as the Canon's shutter.  It does, however, work well and offers shutter speeds up to 1/1000 and flash synchronisation at 1/125.

This camera has automatic film loading.  You pull the film leader out to the green mark on the right and wind on.  One of two metal loops will then pull the film onto the sprockets and around the spool.  This works very well although the manual mentions that with particularly curly film it might be necessary to manually move the metal loop over the film.

Light seals are foam by the hinge of the back and black 'string' along the top and bottom of the recess the back fits into.  These pieces of string look rather amateurish but have the advantage that they will not deteriorate like foam always does.  On this camera the string light seals as as good as new while the foam light seal by the hinge is reduced to a sticky mess and needs to be replaced. (edit, 27-2-2017: I am advised by James Hays that the strings are not original items and have been added by an owner.)

Sample pictures.

These pictures are taken on Agfa Vista + colour film from Poundland (£1.00 per cassette!) and developed and scanned by Snappy Snaps in Lincoln.  I am quite pleased with these.  I have also tried out the Vivitar 2x teleconverter to see how it performs.  I quite pleased with the results - a teleconverter is never going to be as good as using a designed lens - and I think the teleconverter is usable for non-critical work.
