I just found myself an f9 355 G-Claron. It has indicated f-stop markings down to f64. The lens can be stopped down to at least two more stops, to around what would be the equivalent of f128 (and then some).
Question: have the conservative German lens designers said, in effect, that beyond f64 they feel resolution suffers significantly enough (due to refraction) that they are not recommending exposing at smaller than f64?
What about for contact printing? (Yes, I know I'll probably just have to expose at those tinier apertures to find out!)
Thanks!!
