Hi, so overall is this a nice lens? Compare to CV 35mm/2.5 (I have one came with the Bessa R)? I see BH has one for about 300 bucks.
The CV 35mm/2.5 is a modern lens with multi-coating, will be sharper and contrastier. The old Summaron 3.5 is a single-coated lens of older design and will be lower contrast and creamier. They really can't be compared to each other. Each can produce fine pictures, but they will be different from each other.
