Consider how you'd best be able to get two similar sized
stationary objects in simultaneous focus. Obvious answer. They
should both be the same distance from the lens. Are there any
objects that would cause the hummingbirds to be more likely to be in
line, such as aligned flowers or feeding stations? If so, position
yourself perpendicular to that alignment.
Next, since the birds are unlikely to faithfully honor your
alignment wishes, try to maximize the camera's depth of field. One
thing to do is use the smallest aperture that won't unreasonably
degrade the image. Measures that can help allow using the smallest
aperture are selecting a high ISO, taking pictures in bright
daylight rather than in shade, and selecting a slower shutter speed.
You did say that for now, stopping the wings isn't a priority.
Last, get as far from the birds as your lenses will allow. That
is, if you wanted to get one object in perfect focus and another as
far out of focus a possible, you'd probably get as close to the
objects as possible, using a macro lens with a DSLR or a macro
setting on a P&S. So try shooting with your EF 70-300mm lens at its
300mm focal length and as far from the birds as practical. I assume
that this might be too far from the birds for the 580EX if you use a
really small aperture, so try to avoid using the flash until you
want to freeze the wings. If you need to use it and the flash can't
handle the distance, using a remote trigger will allow it to be
moved closer to the birds. You'll probably want to use a tripod if
the 580EX won't be used.
