I have a D6 with a Chromega head. I have 2 lenes in the turrent. A 80mm and a 50mm. The 80mm is just fine. The 50mm can't focus. I can get it close but no cigar. I have the head extended as far as I can get it as well. Any thoughts? Oh I tried a different 50mm and it had the same issue. I am almost thinking of bringing my besseler 23cii back into the darkroom just for printing 35mm negatives.
