Wahey!

... I found the manual focus! I know it's a bit pathetic that it took me so long, but I'm one of those people who only refer to manuals as a last resort (I'm not even sure where the manual is). So I walked around taking dozens of close-ups of flowers using auto and manual focus, and comparing them. The autofocus does what I want 80% of the time, but how nice to know how to override it when it doesn't. Look out for more photos of fennel now that I know how to control it!

This is SOOC, and actually I auto-focussed for this one ... it came out just the way I wanted it.
