I was always under the impression that diffraction due to aperture too smal was a lens problem. Guess not.
It's a body problem.
well guys, go to the link below to have a read. Might be useful.
Well try read through the technical details, it's really quite useful.
A rough translation into layman's speak:
Smallest picture before diffraction spoils the picture-
D2X - F8
350D/20D - F10
D70 - F13
1DMkII/5D/1Ds - F16
1D - F22
Just thought that you guys would wanna know.Some diffraction is often ok if you are willing to sacrifice some sharpness at the focal plane, in exchange for a little better sharpness at the extremities of the depth of field. Alternatively, very small apertures may be required to achieve a long exposure where needed, such as to create motion blur in flowing water for waterfall photography.
I know for sure this will change some bits of my way of photography..
