Which would give me the better result - if I wanted to extend the focal range of my 70-200mm f4 - the DX mode on my D810 or mounting the lens on my D7100? Or would the result be the same? Thank you.

Why? The D7100 will give you about 30% more pixels on the image than a D810 cropped.
Thank you for the replys.

If shot at the same ISO I'd put my money on the 810 even though the file size would be smaller.
As the ISO went up definitely the 810.

Mount it on the D7100.
ONLY because the D7100 is sharper than the D810 is in dx mode. NOT because of the crop factor.

Just curious...do you have any reference that supports this?

The D7100 for sure.
I'm not knocking the 7100, its a fine camera. However as far as I can tell many of the opinions concerning crop cameras are just that.
I need more than just someone's opinion to accept it as fact. Sharpness is subjective. Data would seem more reliable or at least more consistent.
Which is sharper would depend in part on the lens being used. The 70-200 4.0 is an excellent lens. I know first hand since I had it. Sold it because the range wasn't all that useful to me.
Attached is some DXO data that although arguably not 100% conclusive, tends to make me think that the 810 would produce a better image with this lens in the DX mode compared to the 7100.
Do you really think that the DX mode would cut the sharpness in half. I doubt it.
This is my opinion and its not cast in stone. I would surely change it based on objective evidence.
I would say FX mode on the 810 and then crop the image.
Thank you for putting up the factacts : you must watch Fox News :thumbup: :thumbup: :-D
