I know some of you don't know or care about the technical side of things, but for those that are interested:
I tried a few different options for the Swifts yesterday; all bar one involved panning with the bird (makes you dizzy ;))
The one I uploaded yesterday was using Shutter Priority; allowing for the panning, 1/1600th was fast enough - This one was using Aperture Priority; I sacrificed a bit of shutter speed for more depth of field (F7.1 - 1/1250th vs F5.6 - 1/1600th on the other one)
Even allowing for this one being a heavier crop, I think the other pic turned out better. So, unless the bird is flying towards me, I won't worry about depth of field next time
