woo, thanks for the bird tip. suppose one day i'll be back to get more shots of them, look out for more shots from me of aussie birds in a week or two...
anyway, another shot from that day, to show the bokeh. Taken in a forest with some hoverflies near a leaf in sunlight, the background was all darkness with a bit of sunlight poking through the leaves behind. (the good focussing on the fly was just luck, all the rest of the shots were oof or moving or both)
7D, ISO250, 1/320s, 300mm, f5.6 (wide open). camera jpeg, no processing, just shrunk to 1200*800, and a 100% crop...
and for the hell of it, a 100% crop of the next shot, from the far top left corner of the (APS-C) frame. not going to win any awards for composition, but just to give you an idea of how the bokeh goes ever so slightly non-circular near the corner, still, i like it...
