Does anyone have any experiuence with wide Russian Medium Format lenses? How does the Mir-26, Zeiss Flektogon or Vega lenses compare to the Mamiya Sekor 45mm?
I used to have a Pentacon 6x6 camera with four Zeiss Jena lenses (East German, of course, not Russian), and the 50mm Flektogon was the best in the bunch.
If you're looking for a good deal on an excellent superwide 6x6 lens, look for a Nikkor 40/4.0 for the early Bronicas. The bodies are cheap these days, and would be worth purchasing just for this lens, if you can find one.
Based on my own experience, my ARSAT 55mm Perspective Control lens is the best of the Ukrainian MF Wide Angle lenses (I like it better than my Hartblei 45mm and my ARSAT 65mm). I also like my 50mm MC Flektagon and my 60mm MC Schneider Curtagon.
The Flektogon is East German - it is a pretty good lens, excellent when you consider the price.
The 65mm MIR has a reputation for extremely patchy QC, while the 45mm is regarded more highly. Arsat do updated versions, plus some Tilt/Shift/Rotate versions.
Then there is the Zodiak/Arsat 30mm which is also well regarded. Mine should be arriving soon-ish
This may give you some pointers - a fairly detailed lens comparison.
The Arsat 30mm is awesome! I use mine a lot. Can't beat it for the price! Its worth having a Pentacon six body around just to use that lens. The 50mm Flektogon MC is very sharp, one heavy piece of glass.
