>>3454052>trying to focus at infinity on a film slr>lens has a hard infinity stop>hard infinity stop looks like it's just a bit out of focus at infinity>focus it at perfect focus>hold down dof preview button just to be sure>it's just a tad out of focus againWhich reading do I trust? Some of my images turn out badly focused but I haven't been able to decide which reading is correct. How do I decide if it's something loose in the lens, the mirror or the focusing screen are a bit misaligned or a combination of the two? Thanks
