Volna 1.8 / 50mm
MC Volna 1.8/50mm bought for me on aukro.ua by Irina (570 UAH), delivered september 9th, 2010.
It's the standard lens for Almaz cameras.
According to J.L. Princelle, Lomo also made:-a Volna 4 1.4/50mm-a Mir 47 2.5/20mm-a Volna 10-K 1.8/35mm-a Volna 9-K Macro 2.8/50mm(seen on photohistory.ru, except for Volna 9)
Tests: Please note that these tests were made with the means at hand, not in a "scientific" way. See here.
The tests are good, unfortunately the barrel distortion and coma* at full aperture are quite annoying. The latest versions of adapter rings to use this lens on a Canon EOS allow the use on a small sensor body , not on a full frame camera like the 5D.
*It seems that this phenomenon of coma is due to an incompatibility between the lens and the sensor of the 400D, the quality is perfect with the Sony α7.
