'tis exactly true assuming you capture the miniumum required for the
output. As long as Jim's f/11 output image is less than 3MP (of the 5MP
available on the E1) there is no diffraction effect at all. And down to
1.5MP no effect at all down to f/16. A 3/4MP image (1000x750) is good
at f/22. DoF too, of course, but I ain't gonna calculate it. :-)
