Enlarger Lenses

greenspun.com : LUSENET : B&W Photo - Printing & Finishing : One Thread

I generally use 6x7 format (but occasionally use 6x6). Could you advise me on the best focal length of enlarger lens? [Sorry this is a basic question!] I've seen 75mm and 80mm lenses - are these ideal lengths, does the difference matter? Many thanks, Ed.

I was told that 100 - 105mm is the ideal focal length, to avoid light fall-off in the corners.

I use a 90mm Rodenstock for 6x6, 6X7 & 6x9 negatives with no visible edge fall off in.

75-80mm lenses will probably not cover 6x7 evenly.Get something in the 90-105 range.I use a 100mm Companon-S,works great.
