Caught some hummers this weekend. Unfortunately, the males were too shy to approach the set-up (see below, 2X430EX, 1X580EX, camera mounted 600EX, all at 1/16 power + 5DMKIII w 300 2.8II +25mm extension tube, f11 at 1/200, ISO 360). Hopefully they will cooperate next weekend.
(not sure why that posted rotated - it isn't on my screen.)
Any ideas for catching them fighting? I got a few, but all OOF. Stochastic success is the likely answer. I thought of a wider lens, but don't want to lose the limited DOF w nicely blurred background. Maybe the 100 2.8 macro? I'll experiment.
