jpegs coming out of the 5D3 are...pooh. however, i never shoot in jpeg mode. i've been reading about this and sure enough, the camera does some smoothing over when it shoots in jpeg, and i think this bird i shot is a pretty good example;
now, the RAW files, whoa! excellent!
need to test the AF tracking more. some weather would help.
lastly, i see Lightroom 3.x doesn't support this camera...
