That shot was taken with an old film camera with a horizontal shutter.
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.

What? You expect me to take your word for it?

This was taken with a DSLR
Not perfect but far better than your example.

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

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
But there are flashes that go up to 1/20000 but not for toy cameras.
