The fisheye perspective of the tiny little 03 Fish-eye lens, mounted on my Q7, gives crazy perspectives. And, though I believe Pentax considers this tiny little lens a 'Toy' lens and not a 'real' one, it certainly delivers. The fixed f5.6 aperture means that, with the right focus setting (using the tiny little lever on the lens to guesstimate distance from subject), quite a bit will be in focus. And, no, it's not an optic made by Zeiss or Leica - but it certainly can create dramatic images.
