Hi,
Is this just a stupid idea from me? or is it not possible or......?
Given the current well performing APS sized sensors in DSLR and having a stash of lenses from you film days......why is there no inverted teleconverter that instead of extending the focal length, shortens the focal length of a lens? Just take your 1.4 50mm, put it on your APS sized sensor DSLR and with help of the converter you retain the same angle of view as on 35mm film.
