As darkroom completion nears, I have started dragging out my garage sale assortment of enlarging lenses and cleaning them. Just wanted to know if ANY of these lenses would be considered a better than average lens for my Federal 470 enlarger (no snickering please!); 1. Federal Ocatar 135mm f4.5 Anastigmat 2. 16,5 cm f4.5 Laack Rathenow, Doppel Anastigmat 3. 7.5cm f4.5 Fujinar-E, Fuji Photo Optical 4. 5 cm f4.5 Fujinar-E, Fuji Photo Optical The Laack Rathenow, Doppel anastigmat is a wonder; wonder where the the heck it is from! Anyone?
