W.A. Enlarger Lens for 5X7?

[Bob Salomon]

You are absolutely right that I have no experience with the WA 120mm. I'll have to trust you on the other part, since all I have is a 135mm Fujinon EX and a 150mm G-Componon -- so I have no reason to "try out" the WA 120mm, anytime soon.

But the original question was about a wider lens for 5x7 -- and the Rodenstock literature lists the WA 120mm for 4x5".

You brought up the 135 and 150mm 45 lenses.

Yes, only as an example of using different lenses for a particular format -- and some reasons to use one over the other. I could have used 40mm vs 60mm lenses for 35mm, just as well. Computar made enlaring lenses for full frame 35mm film from 25mm f2.8 (9 elements in 7 groups) to 65mm f3.5 (6 elements in 4 groups). Of the 25mm (no, it is NOT designed for half-frame), they state:

"The severe illumination fall off, common with most wide angle lenses, is not present with the Computar 25."

But what do they know? They only make enlarging lenses!

I was not trying to suggest using lenses designed for 4x5" with 5x7".
