Some time ago I did 4x5 for awhile. I enjoyed it tremendously but after moving away from Madison to the Wild North Country I stopped. Darkroom work is difficult at best and printing essentially impossible in my trailer. But I had this really nice field camera I'd built on the shell of a Crown Graphic - full front movements, cleaned up, pulled the shattered rangefinder, etc. So I hacked up a film holder with a m4/3 to Nikon F adaptor that I put at the center of the film back. Unfortunately, I have sold all my functional m4/3 gear - the one attached to my hackery has a busted back screen - so I have to pick up another cheap E-PL1 or the like to use it again.
The lens is a Bauch & Lomb licensed Tessar from 1912 - 1914 F/6.3 and just beautiful. I have it rigged to a Polaroid MP-4 shutter. But talk about crop sensors! That's a 5x8 coverage lens (~ 240mm focal length) onto a m4/3 sensor
I also have a nice "wide angle" Ektar 127 I use with it.
