Originally posted by Pål Jensen Diffraction is a non-issue except for pixelpeeping. There are tons of fine art prints on peoples walls shot well into diffraction. Many of my 645 images are shot at F:22 or 32, and although this can be seen under a high magnification loupe (this is film), in the final print no one can tell. Just apply a tad more sharpening.
you can't see diffraction with film because film resolution is extremely low, you'd be lucky to be recording the equivalent of 12mp with mf film.
see below for the math for when diffraction limits resolution on high resolution cameras.
Originally posted by Pål Jensen I have much more control over DOF with my K3 than my 645NII. This is based on real life experience. In fact, there are images and cant get with the 645 which are easy to achieve with the K3.
we are talking about digital, not film, and crop vs. ff, in this thread, it's comparable because both have good lens availability, while mf is severely limited in that regard.
you aren't providing any kind of specifics there, so it's impossible to determine what you have done.
