I have the above enlarger, with a colour head and a tri - control unit. I having trouble tracking down some condenser's so i can use it up 6x7. My question is if i stick a 80mm lens on it, would there be a big difference than to use the correct condensers. I do understand how important they are, but could you see it. If i can't find the parts i will have to settle for another enlarger. That come''s as my next question. Regards Graham.
