I've always used manual focus or "selection" autofocus on my camera. But we have these lovely black carpenter bees nectaring at the sweet peas, and I'd love to catch one in flight.

I'm much too slow for manual or selection focus here, and if I try to focus on a plane and wait for them it'll take weeks (there are too many flowers for them to choose from).

So for the first time I'm trying "dynamic area" autofocus...

@angst_ridden I this a handheld shot?
@old_hippie yup. Hand-held. 600mm at 1/400th of a second, f/6.3. I need to crank up the shutter speed!
@angst_ridden Seems it was fast enough. Nice of your subject to be still.
