With a reasonably normal lens, f/22 before diffraction strikes. You may want more selective DOF, and shutters often don't go or aren't good (even more so if old and worn) beyond 1/125-1/250s, so that you may sometimes want to pull or switch to slower film.

Dear Chris,
Yes and no. I believe that they are sensitometrically identical, but of course I process 35/120 one way (small tanks), and 4x5 another (Paterson Orbital) and I tend to expose 4x5 more generously, as the penalties (reduced sharpness and bigger grain) are insignificant with large format.
As an aside to Sevo, diffraction is unlikely to be an issue. Using the rule of thumb of 1500/f. no, f/32 still gives a theoretical limit of 46 lp/mm, at which point film location is likely to be at least as important and the greater depth of focus will probably improve sharpness, or at least not detract from it, as compared with f/16.
Cheers,
R.

Keith,
I find that Ilford HP5+, exposed at 250, spun round and round in a Jobo tank filled with Xtol 1:3 to be just about bullet proof. Certainly better than my meager skills. HP5+ makes me look almost good.
Enjoy!

Dear Wayne,
That's what it's about, really. How many of us are better than our cameras and film?
Cheers,
