Hannes, have the Soviet lenses actually been tried on the Bessamatic?... as I am told the bayonet is the same, as is the aperture control, but like Retina it may not match the vital cut out, which can be filed into place on the rim of the bayonet. A Retina DKL will jam on a Bessa, but can be modified, and I suspect the same may be apply for the Soviet version of the DKL mount. However the Soviet DKL may well be different in other details, and anyhow I have not got a Soviet DKL lens as yet! Information on the net says Braun DKL fits as does Iloca DKL, it was the Kodak version that was out of step. Stephen Hi Stephen I do not have a Bessamatic (yet) but there is some detailed info on the camera site of Guido Studer www.g-st.ch/privat/kameras/zenit.html#zenit4----- Die Zenit 4/5/6-Familie verwendet ein Bajonett, das ähnlich dem der Voigtländer Bessamatik konstruiert ist. Die Objektive sind allerdings nicht kompatibel und können, wenn überhaupt adaptierbar, nicht auf unendlich fokussiert werden, da das Auflagemass nicht übereinstimmt. Gewisse Objektive lassen sich auch gar nicht zwischen den Systemen tauschen, da das Bajonett nicht völlig kompatibel ist. Das Objektivangebot für die Zenit 4/5/6-Familie war eher bescheiden: Neben dem Standardobjektiv Vega 3 (50mm/2.8) existierten noch das Mir 1ts (37mm/2.8), das Jupiter 25ts (85mm/2.8), das Taïr 38ts (133mm/4) und der Voigtländer Zoomar-Nachbau Rubin 1ts (37-80mm/2.8), der im Set mit der Zenit 6 geliefert wurde. Ein hübsches und sehr nützliches Detail, das beim Vega 3-Objektiv von Voigtländer-Originalen oder auch den Objektiven der Kodak Retina Spiegelreflex-Linie übernommen wurde, ist die DOF-Anzeige (Schärfentiefenbereich, Deep of Field), welche sich je nach gewählter Blende verändert. ----- Hannes

These are only comments, not contradictions! but the objection to infinity focus is strange as the mount to film distance is the same. I still think it turns on the Soviets copying the Retina Reflex version a bit too accurately! I am not going to buy a Russian one just to find out!, anyway they are very rare in the UK, and would have to be bought in from Russia etc.

There is one in Austria for sale with 3 lenses, filters and case. If I buy it can try and post the result. If it is possible to use the Rubin zoom on the Bessamatic. I would be very happy. Hannes

Then they are different, a very great pity, as they must be the same bayonet mount itself. Another list said 44.70 for both. A story on a couple of websites is that the Russians bought several DKL Retina lenses at a Brussels exhibition and used them to design the Zenit 4,5,6, mount. As they disregarded Patents etc., totally, it is a surprise that the mount ended up a small amount different. Stephen.

I was due to go out for the day with the Bessamatic, but the weather was wet this morning, so out tomorrow instead. I'll cross check the meter with a Weston to make sure the exposure is exact. The shutter is accurate on a speed checker, so any problems should be down to the processors!

Test film away to the processors, and a very nice condition 135mm F4 Super Dynarex telephoto lens has arrived from Brussels in Belgium....after taking the test shots! So another go this week, with the standard, 2x converter and the 135 Tele, which should work with the 2X nicely.
The viewfinder is still amazingly bright with the Super Dynarex in place, after all it is only F4. It is down to the fresnel lens being a bit courser than modern ones in other SLRs.
Only downside is the close focus distance is 4m, I suspect to keep the lens size small.

As well as the 2x converter, and the 135mm lens, I have now got a DKL to M42 adaptor in the post. It is M42 to allow it to fit as many cameras as possible, as the M42 can go into a Micro 4/3 M42 adapter for digital uses. The Chinese DKL adapter is excellent quality, and retains control of the Bessamatic aperture by providing the outside of the adapter as a substitute aperture ring, with marked apertures. As it is turned the aperture depth of field markers move correctly as well. Of course the lens is a manual lens at that point. it retains infinity focus correctly. Stephen.

The problem with the 135mm, that of the 4 metre closest focus distance, will be hopefully helped by a set of Chinese close up lenses, including a +10. The same 40.5 mm thread is used for the standard and the telephoto lenses. Previously I have used similar sets on the Micro 4/3 Olympus, and they are good quality.
The metal lens hood in really meant for a rangefinder camera, but provides a small lens hood of good quality, again from China.
