It's not really about price of the lens, other than it's funny to add an adapter that's over 3 times the lens' cost.
Sorry, the 28-105 II USM Macro and I have a bad history. It was one of those lenses I'd heard decent things about and thought it might make a good lightweight all-around lens. Unfortunately, it came close to ruining an aerial assignment I had, which was saved by the 24-70L on a second camera.
It's hard to believe the poor IQ would reverse itself by turning the lens around. Maybe at f/11 or f/16 it wouldn't be so much of an issue using just the center of the image circle?
Sami, obviously I'm coming from the other direction. Hey, if it works, it works. I know Novovflex makes some outstanding products, including rails and other technical pieces of high precision.
