With only a few minutes outdoors today, the M9 and 50mm Summicron came along. For certain I was rushing my shots and not paying attention to technique day before yesterday, which is what got me all the almost-but-not-quite results.
With only a couple of wides left to check, it seems safe to say that the rangefinder is accurate. Although shooting time will be limited over the next couple of weeks, it looks as though the M9 will make the few hours I get here and there enjoyable and rewarding.
M10-R relegated to backup, maybe?
