front-focussing ? back-focussing ? how about doh-focussing ?
Really, this obsession with MTF charts is undoubtedly unhealthy for the wallet but it can also be so all-consuming it confuses solving the most obvious of problems. After getting annoyed with the auto-focus on the 350D and going back to the joys of a ‘proper’ manual lens (Zuiko 135mm with EOS<>OM adaptor) I had then become frustrated with the viewfinder: too small, too dark, too tunnel-like when compared to my aged OM-10 and plainly the cause of all my manual focus woes (being just that little bit wrong when viewed at 100%).
Or not. How about that tiny, tiny diopter wheel next to the viewfinder. Hmm, how about I actually try to find the centre zero setting ?
Now at least I know that I can put off a visit to the opticians for another year, and I really don’t have to go lusting after full frame D-SLR’s !
