AFCSoff.
Superlative images.
I see you are using a D70, I have just sold mine having had it since a month after launch. Now run a D200.
I have two friends who are pro snappers [Canon 5d/1D MkII and 1Ds Mk11/1D Mk111] who you put to shame.
Are you running the 80-400mm f/4.5-5.6D ED VR AF ? They look handheld or possibly you are bloody good with a monopod/flex head.
1340 gms means you must have Popeye's arms to be busy for that length of time ! I have the 70-200mm f/2.8G ED-IF AF-S VR and know how the weight catches up after a while.
Once again fabulously good shots, I am sending this url to all the people I know who think they can take an image.
