OK, here are some shots with the new camera, not necessarily birds

This was handheld at 1600, no noise reduction applied, f8, 1/200, EV at 0, 100-400 IS at 400mm.

Not so sharp in my view but this was using TV at 1/1000, f11, lens at 400mm, EV -1/3, ISO 800 without NR.

A bird at last! And yes the whites are burned out on the far wing. But settings were: ISO 800, f5.6 300mm IS lens +2x TC, EV at 0, and 1/3200
After a short time in the field I am blown away with the noise levels (or lack thereof) on this camera. They are very usable at 1600 ISO. I need to recalibrate my compensation for highlights - there is more tolerance in this camera and I like the highlight priority feature - I don't think I am losing much on the shadows.
This body feels lighter and better balanced than my 1D mkII and the battery is the main reason. I'm not sure the AF is any faster but with the 300mm and the 2x TC its quick enough. Without the TC its lightning fast. I haven't tried Live View yet nor the AF fine adjustment. I'm a happy bunny so far.
