I never said the lenses are good just that they are more telecentric. There are a lot of lenses that can be put on the NEX with adapters, but the ones that will not have lens cast issues are telecentric lenses and they are usually large. So the problem is finding small wide angles.
DSLR lenses would work fine and so would Leica R-lenses.
What pleases me is that cameras like the NEX line give a sudden new lease of life to the likes of Minolta MC/MD and Canon FD lenses, whose flange distances were too short for adapting onto the likes Canon EOS, Nikon, Pentax, and Sony/Minolta-Alpha [D]SLRs. I loved my Minolta MC/MD system, carefully built up from used pieces, but I traded it in 20 years ago to upgrade to M645 medium format! Now I expect that exceptional lenses like the 85/1.7 MC I had go for multiples of what I originally paid for them.
