Interesting idea but pretty useless to me..

Instead, as a college student who has too much time on hand, I whipped out the Omega 45D and a 20D, without the $150 adaptor, took off the GG and placed 20D right behind the bellow, and compared these two lenses: Fujinon L 210mm f5.6 and Canon 70-200mm IS f:2.8
Fair test? Probably not, I tried to line the 20D at the center of the back standard, it's clearly off centered (like 0.75" to the left) but what the hey... Note, the 70-200mm lens is pulled back because the subject is too close to the camera (less than 1.4m).
f64 has a lot more DOF but sacrifices sharpness and quality, actually, pretty ugly :P
As we all know, 2-3 stops down from wide open of a lens is the sweet spot..
