How sharp will the results be from Zeiss Jena Pentacon 6 medium format lenses if we are cropping to S16 format? How would they look if we intercut them with Zeiss S16 super speeds?
I was looking at 120 and 180mm/2.8 aus Biometer. My thought is, when the lens is cropped this much, the resolution may not be up to that of the super speeds. I have seen them (SSs) on the projector resolving a very crisp 200lp/mm. For bigger formats, the lenses don’t need this in order to look good. A 35mm format cine lens that can resolve 100lp/mm will look as good with 35mm film on screen as the 16mm SSs blown up and projected to the same screen size.
I think the zebra (black and aluminum striped focus ring) that some say are best are only single coated. Some interesting chat and pictures here.
Any thoughts? The Jenas are cheap enough to just buy and try. Perhaps if this cropping affecting screen resolution issue is real, then the M42 Jena lenses are better?
PS: I think the zebra Biometers are single coated.
