Audubon couldn't have done better. But you, Chris, do this with a lens and the bird live to see another day.

Audubon, like other flawed great men, became famous with achievements that depended on practices we might frown appn today. In his case, by hunting down, killing, stuffing and drawing these wonderful creatures.........and is the namesake of a "Society" that protects wild creatures especially birds. If he had your camera in his hands, would he needed to have killed them too?

Anyway, your pictures are so sharp, densely colored and superbly seen! Who needs to kill them?

In answer to your query, these were all shot with the Nikon D500 coupled to a Nikkor 200-500 which, with the DX format gives me an effective range of 300-750. Essentially, I had the same focal length crop factoring with the D810 but not the speed of focus lock and tracking capacity and incredible clarity at each end of the lens.

Did you mean the D500 gave everything that the 810 would have delivered, but for focus speed and tracking, because you do have incredible focus with your combo!

No, I meant the D500 beats the stew out of the D810 for focus lock and tracking.

I had to look these up. The D500 is 18 months newer and has 151 focus points to 50 and at 1.6 mag about the same number of pixels to the reduced field. It is also substantially ($800), less expensive to boot!

I am more familiar with Canon DSLRs and they also have great glass, but not a 200-500! However, they have a 200-400 with a built in x1.4 expander, that is pretty damn good....and magnificently outrageously expensive. I found my 300mm 2.8 so unwieldy that I started to think of getting a helper to lug it for me on treks.

Thanks goodness, the Nikon and Canon lenses can be used with the Sony A7R DSLR, but perhaps the Sony A99II would be a more smart choice for its rigidity and use of Minolta lenses. Like the D500 it has a Pentaprism and fabulous focus. I wouldn't trust the Sony E mount for your 200-500 lens! Not strong enough, I'd imagine, although birders probably have written on this extensively.
