(I also posted this to the Schneider board but thought someone here probably has some experience w/ this.)
I have a 210 Apo-Symmar and I was wondering - what would happen if I unscrewed t he front element and just used the rear "cell"? I played with it (set up and foc used - no photos) and would estimate the focal length at approx. 14" or so. This seems like a good focal length for headshots on 4x5, and if it's not fully corr ected for spherical abberation then so much the better, right? (After all, we're talking headshots of women here!) Has anyone done this and if so, what were the results? Would this also cover 8x10? What focal length would just the front cel l yield, and would it be even more uncorrected than the rear one? (That would be my guess.) And why does the focal length seem different if I flip the rear cell around?
