Hi all. Recently I decided that I want to get back into B&W film photography. In an attempt to save myself a large cash outlay on outfitting my darkroom, I attempted to rescue my fathers old equipment. Now unfortunately it had been stored in some cardboard boxes for the last 15 years, and they had become infested with rats nests. The old Durst F60 looks to be unsavable (at least not without finding some extra parts), but enlarger lens wasn't quite as bad. It was a Leitx focotar 1:4.5/50. It was stored in what I assume is its original plastic container with silica crystals. Unfortunately the rats managed to chew a tiny hole in the plastic container, not enough to get into it, but enough to let the humidity in. So while the lens looks okay, there is some fungal growth on the lens, and the adjusting the f stop seems to be rough. If I was going to use this enlarger lens, it seems it will definitely need to be taken to get repaired. So the question is, is it worth it? I'm not sure how much the repair cost will be (or if anyone will even be able to do it where I live), so I'm not entirely sure whether its worth it, rather than just buying a cheap 2nd hand lens. Was the focotar a particularly good lens?
