You can not find a picture taken with a DSLR haaving such a bad distorsion (only tip of the blade will be bent) P&S cameras cannot do it better, flash will be useless and without flash having a ridiculous fast exposure will produce a black image.

Can you find any P&S shots of the Apache? There is NO distortion because there is NO shot. DanP

Ehmm, with CHDK the aperture has to be f/8 for 1/40000 s. Pretty much useless for photography but good for trolling. There is a reason why no manufacturer makes such ridiculous fast shutters. But there are flashes that go up to 1/20000 but not for toy cameras. DanP |
