The M8 has a crop factor of 1.3, so the lens was effectively 65mm though I kind of think it might have been a little less. Those Russians round up or down a little more readily. Surprisingly, it seems like a pretty good lens. Soft wide open with a bit of a halo. But it improves stopped down and the wide open nature of the lens isn't unpleasant. I did punch up the contrast and sometimes increased the saturation a tiny bit in a way I usually don't have to with the 35/2 ASPH or 50/2 Summicron. Right out of the camera, the color/contrast is a bit flat. Anyway, here are a few edited pictures. I have to say I've been using this as a body cover for a while. Maybe I should shoot with it more.
