Exakta RTL 1000 issues - help appreciated

    I have an RTL 1000, which fires the shutter immediately, does not release the mirror and does not retract the aperture setting pin when wound on. It appears that the winding mechanism is not triggering the reset of these items after the exposure is complete. Shutter timing is fine. If I physically reset the aperture bar and unlock the mirror the camera winds on and fires correctly but then remains stuck in the mode I described.

    Appreciate any information as to what may be causing this and if possible a copy of the service manual for the camera.

    I was going to suggest Rangefinder Forum as being more the sort of place where Exakta knowledge might crop up, but I see you have beaten me to it. If you take a look in Classic Marques, someone has just done a fix on an Exa, but I don't know how much they have in common (you wait for years for an Exakta product to turn up, then two come along at once!)

    My first camera was an Exakta RTL1000 that I owned and used from 1973 to 1980.
    The SLR body was very similar to a Praktika one, but with an Exakta lens mount and removeable pentaprism housing (this allowed the use of a waist level viewfinder or a much larger pentaprism housing that included a TTL light meter).

    I found this webpage about service manual for East German cameras, which has 'An article about servicing the Exakta RTL-1000'.


    Perhaps one of the specialist repair firms that sometimes advertise at the back of AP could also help, but any repair might not be economic.

    If you go back to the camera collector website, you will see that I left a link to a service article about the Exakta RLT-1000. On the same page there is a service manual, in German, for the Praktica L.

    The Exakta RTL-1000 is based on the Praktica L - it is very different to the older style Exakta.

    Ah - so a sort of non-Exakta. InExakta, perhaps?

    I suppose it's a bit like the relationship between modern Audi and Volkswagen cars, different appearance but virtually identical underneath.

    No - it's like the difference between a 1930 Ford and a Trabant. The older Exakta has a cloth shutter, running horizontally, left hand wind lever, and a trapezoid shape. The RTL-1000 has a vertically running metal shutter, right hand wind, and is a bricklike shape.

    Yes, it turns out that the RTL-1000 is a Praktica in all but name, I think (it's certainly a Pentacon product), and owes pretty much only the lens mount to its Ihagee namesakes.

    ETA - think BMC badge engineering

    Well not Exaklty. BMC, possibly, but certainly not BL-style badge engineering. The RTL 1000 has quite a few differences from the interchangeable-viewfinder VLC series - obviously the mount, with the VLC having the Pentacon Electric version of the M42 mount, but also with the viewfinders - you can't fit the RTL metering prism to the VLC, it's unique. The VLC series had metering built in to the body, so metered with the WLF, magnifying finder, or standard prism. Shutter release is also different - the RTL has the option of setting timed long exposures on the self-time, the release button isn't a button as on the VLC or other L series models, but a sliding slab, for want of a better word, and there is an additional shutter release on the traditional - for Exakta - left hand side of the mirror box, to accommodate older Exakta lenses with shutter buttons.

    So it's more Riley Elf and Morris Mini-Minor rather than Austin or Morris 1100 versions of badge engineering. :)

    I've never seen an RTL-1000 - they are vanishingly rare here, as are Prakticas with interchangeable finders.

    I have sourced a digital copy of a genuine Dresden service manual for the RTL 1000. It is in German, but as I am in Germany and learning German, that should work out! Now all I have to do is fix the wind on clutch on my Kiev 4 it is missing a spring. I have the service manual for that too - It's in Russian!

    Typically, having posted upthread about the rarity of RTL1000s, I've just received one that popped up on an online auction here.

    I think I may have found a kindred spirit!

    My Allen Scythe hasn't been home three weeks yet... I've already bought a pair of forestry guards for it, and have the carb in pieces ready to go in the ultrasonic bath tomorrow. And I'm not planning on doing anything with it before I finish at least three other projects...

    I'm no better with cameras either.

    I'll mention the Praktica VLC here too, and see if one of them appears in a local auction.

    Sold my VLC a couple of years ago. Fetched £25 on the bay. I used to have the 28mm and I think 135mm electronic lens for it. Back in the 90s I used it professionally as a backup wedding camera. It did the job and produced some very nice prints.

    I have an LLC, which I bought new in 1973, which was my only camera for many years.

    Wouldn't you know it - I bought a Praktina FX from a downsizing collector, and when asked if he had other cameras to sell, he had a Praktica VLC2...so I bought that as well. My wife is not pleased...

    Heehee! I'm lucky - my Mrs collects books faster than I collect cameras (and grass cutting machinery), so I get a free pass if I don't mention it.

    RTBC - got some good info from Hans Kerensky on sorting the stiff focus on my "new" Super Ikonta last night.

    Thank you so much for posting this! I had similar problems with my Exakta RTL-1000, the grease in the 'runner'(?) of the upper shutter had turned to stone and was stuck. This prevented the upper shutter to come down, and the triggering of the mirror release and aperture pin. I have found that for the mirror the release and come down again after the shutter has closed, the lever with the red arrow needs to be triggerd
    by the sliding pin in that is hidden on this image but runs in the indicated track:

    The upper shutter was stuck as I mentioned, and I fixed this by taking out the plate on which the shutter is held and cleaning it (along with moving it untill all the old grease either came loose or became half fluid again). This made the sliding pin move again, and able to trigger the mirror release. I would advise to check if your upper shutter closes properly, if the sliding pin is where it should be, and if the two are making contact. It could be possible that the spring in the upper right of the second picture (next to "closing blade tensioning arm") is fatigued beyond the point of producing the force necessary to trigger the lever.

    Hope this helps someone!

    Kind regards,
