So I am making the move! I have an OLD bessler c23...it doesn't even say c23 on it! Anyway no matter which lens I have on it, I need to stop it down to 16 just to get a mildly sharp image across the plane of the neg! I am sure that it needs to be realigned and fiddled with. But I am done with it. It is huge, clunky, and I have some money to burn! So the question. I shoot mostly 35 with a dabble in 6x6. Looking for a sharp enlarger. 3" square filters would be nice. Used, New...not such a big deal. But I want it to be SHARP. What is a good bet for Enlarger and Lens... So I can start the research. Thanks. Mike.
