Jesse, when I made the switch to M from R I did wonder about this, as
there's no focus check at the sides of the field. But in reality I find
it's not a problem, actually I seldom get an out of focus shot with he M's,
whereas with the R's it was a problem. In fact that was the main reason I
switched. And I'm usually as close as I can get to my subject.
I should think depth of field just takes care of it.
