Originally posted by debasercl I think it will work on DSLR bodies, specially after watching pictures like these where you can see that the lens do not projects far into the body.
The lens may not be focused at infinity in those pictures.
However, the DA40 moves less than 5mm
between infinity and closest focus (40cm),
while the mirror clearance is around 12mm
to the back of the K mount on APS-C,
so indeed there shouldn't be a fouling problem.
But I assume no responsibility if it turns out that there is:
You try it at your own risk.
