Get an 80mm Biometar from the Pentacon. You will be very happy with it. I have 2 and both are top notch lenses. The Volna's not so much. YMMV.
Personally, I could not see any difference in the performance of the Biometar (I have the Schneider-Kreuznach Biometar for the Exakta 66) and the Volna-3. The advantage of Volna-3 lies in its 0.5 meter closest focusing distance.
The only issue is that the inner surface of the rear tube is prone to flaring, so it must be painted matt black. This issue was always wrongly attributed to the DoF lever, but it is not the cause.
My favourite lenses have always been:
- Zodiak-8 for landscapes and architecture (as long as it is aligned with the horizon);
- Flektogon 50 mm;
- Vega-28 120 mm and Calejnar/Hartblei 150 mm
- Arsat 250 mm
- Pentacon 300 mm
- Arsat 500 mm APO
Leatherette is somewhat expendable.
