Just the other day I bought a Beseler 45M enlarger. It came with 3 lenses, a 75mm, a 90mm, and a 127mm. The 127mm is intended for 4x5 use, and I projected a 4x5 negative yesterday just to check out the enlarger and the corners are getting clipped with the 127mm. Why is this? Do I need a larger focal length to cover 4x5?

Normally the shortest lens for 4/5 enlarging is 135mm with a 150mm being preferred. I never heard of a 127 enlarging lens. The only 127 were on Poloroid cameras and some Graphic 4x5`s. I remember usind the Polorid on 4x5 and it barlly covered at infinity, so it should be ok for enlarging.

Then it could be the condensers.

There are wide angle enlarging lenses for 4x5 like the 120 Rodagon WA that fully cover 45 at all apertures.

Also, did you make sure that the top bellows is moved to the 4x5 marker? The top bellows should be pretty well compressed.

Cheers, Richard

I've used a 90mm lens to enlarge a 4x5 to 8x10 on my Saunders 4500II with comparable good results to my 135mm.
