Hello,
I've recently made the switch from 4x5 slide film to a digital back since film and especially E6 development for 4x5 became unavailable in my area. So I'm in need for a nice wideangle lens, a 45mm would suit my needs perfectly. I use an old Sinar P with DB shutter.
Currently there are some "Sinaron Digital" 45mm lenses on what looks like non-recessed Sinar DB lensboards listed for a quiet reasonable price on a big auction site.
So my questions arose: What is their flange back distance/extension for infinity? Their focal length or a bit more like some of the newer Rodenstock Digarons. I think those have about 70mm.
The lenses are explicitly listed as "without shutter", should they have one by default or do they fit my ancient DB shutter?
I looked at the sinar website but didn't find any information about this lens there, they only list "Sinaron digital CEF" and "Sinaron digital CPL" lenses that are both equipped with a shutter, nothing about a plain "Sinaron digital".
Help is greatly appreciated.
