Is there any technical reason why one couldn't build a high-quality
optical converer to go between a DSLR body with 1.5x crop and an full-frame

old glass, but the wideangle and fast normal is pretty difficult. I just
bought an SMC-M 50/1.4 and an SMC-K 50/1.4 for my -DS and I *love* the
speed, sharpness, and bokeh. What I don't like is the effective 75mm FOV.
I just don't understand what is so difficult ...
It's the "fill with old glass" bit that he finds difficult. It will be
hard for him/one to find an excellent K or M 35/1.4 for 100 USD :-)
Of course, as you said, any addition to the optical formula is a
problem.
