I have a Bender 4x5 camera with two bellows -- the original and a bag.
I have a 210mm Nikon lens but rented a 90mm a few years back.
I do not, however, recall if I was forced to switch to using the bag or
if I was able to compress the original bellow and get my images.

Before I put my money down on a wide lens such as the 72mm, 65mm or wider,
I would love to hear of any physical limitations (such as the need to use a recessed lens board, etc.)
that actual owners of Bender 4x5 cameras have run into.
