At 300mm, fall off would be way outside a 4x5 negative. I use 125mm
cameras with no noticable fall off. Pretty long focal length at 300mm
though and loooong exposures.

Hello:
If one set up a 4x5 bellows camera for pinhole with an appropriate
pinhole
for double extension (say 300 mm), placed the bellows at 300 mm but
used a 4
x 5 filmholder, would that place the worst of the edge falloff outside
the
4x5 image? It seems to me that this would work, at least to reduce the
effect somewhat.
