I'm looking for suggestions for a lens to use on 4x5, in the 120-135mm range, that would give a nice fall-off at the edges, preferably on the short dimension of the film. Something like the soft edges you get on a full 6x6 Holga frame, which goes close to black in the corners with a nice gradation. So I'd crop the 4x5 to 4x4. Failing that, something that fades out on the long dimension could work.
Shorter focal lengths do this, but I'm having trouble figuring out the right thing to look for at this length.
I'd prefer to find something lightweight in a shutter. Compur with many-blade iris would be good...
Thanks for any ideas!
