DOF with a 500 f4 is narrow. I cant tell how far away the birds were, (100 feet or a bit more) I also do not know if you cropped the shots. But consider that you dont gain much DOF by shooting f13 over f8 (are you shooting a mannual lens? IQ is likely not noticable either, so I'd have shot it at f8 and gotton all the shutter speed I could. Now if you want to increas the DOF bump it up to at least f16 and now your talking about 10 feet as appoased to about 5. . .

Marty,

I love the shot of the pair flying! Wish I had gone out Saturday now. Sunday morning was a disaster, ISO 800 plus just to get the shutter speeds up. I got some shots from about 20 yards but the noise on my 30D really does not make then usable. Wind was terrible but the Eagles were really moving as they played in the strong wind currents. Not much of anything else moving out there.

Thank's again Tony. I wish I could get your tips on all my shots. Actually was 370mm at about 200 ft, no crop.

O man, im sorry, i thought that shot was with the 500 f4, my bad, i see now that it was 370mm, boy did I blow that. However, my points are just as valid. DOF at 200 feet shooting f13 is about 50 feet which is good for that shot, right?

In any event, you did a fine job no matter what your reasoning for selecting camera settings (and I dont think anything you did was wrong), I always say if it aint broke dont fix it! nice work, I wish I could get out there and shoot some of those birds myself! I'm about a week away from the birds starting to show up here in east glacier park. . . Thanks again for your great images!!!!
