This is such a fun image. Love the low angle, the comp and the behavior.
Pushing iso for more ss +/ dof would have been an option, as the birds on the right and behind seem to have some motion blur on the head.
Fun image, TFS.
Mk III should have no problem at all going to ISO 400 and I would not hesitate to use ISO 800 for action.
As long as you try your best to "expose to the right", noise should be quite manageable.
Very pleasing, I like the position odf the birds getting cooperatively tucking in
viewing angle is great, raising ISO to 400 would have nailed it as you were obviously steady!
nice colours, unusual all round
I really like the comp and your low angle . I assume your were in the water? The design the three birds create with there positions is great.It's unfortunate that the right side bird and the bird in the back show a little blur.
