Great detail in both shots. Do you recall how far you were from the birds?

Thanks Bob.
The woodpecker is approximately 12' to 15' and the chickadee is about 8' to 10'.

The real issue here is not bang for the buck. As the discussion has evolved, the issue is what would have happened to these bird images if that same 300mm f2.8 lens were put on a D7100 and the same shots taken, cropping so that the birds occupied the same area in the frame. Would the detail be less clear, more clear or the same? I'm not going to speculate, but the argument that I made earlier and that has since been repeated using different language suggests that the D7100 image COULD be better.
As an example of what can be done with a D7100 and a much cheaper lens, the Nikon 70-300mm VR, here's an image of a tiny 2 1/2 inch tall hummingbird taken from about 8 feet away and severely cropped...about 2x. The focal length was 240mm.

Its a very good shot but also much noise.

How do you get close to the birds? I generally have a couple of seconds to get close and take a pic before they fly away. So 9 times out of 10 I don't get a good shot.

Bob,
I have feeders set up and perches close by. I'm in a blind on my deck. Don't have much more than a few seconds to shoot, but they keep coming back so I get multiple chances.
My neighbor thinks I'm nuts. My wife thinks I haven't grown up but she is supportive.

Do you have one of these shot with the D750 Full Frame you have.

Beautiful shot Bob, great job in processing.
I just setup 9 ft from the feeder and sit still. They come in with slight hesitation at first then feed away.

OK, here is my point of view. The full frame vs DX is not really a sharpness issues, that is really the camera and especially lens quality that affects that. To me it is the fact that the FF is roughly 1.5, different with different camera manufactures, the size of the APS-C. This creates a larger area for the sensors to collect photons or light. The light excites those points and image is created. On a full frame because it has the larger area this gives more distance between those points and less electrical noise, that noise what we see as noise or called grain in the film days. So a full frame has the potential to have a higher ISO on the full frame than on the APS-C. The images will look cleaner and smoother at higher ISOs. I do not have a FF camera and continue to shoot crop cameras because of cost. But someday I hope to move to full frame.

Spent the last couple of hour updating my Win10 Pro. Your image looks much better now for some reason. Thought you should know. Very nice.

Thanks for the info. Can't argue with success.

All true, but to get the focal length of a 500mm or 600mm lens on a DX sensor, which would be 750mm or 900mm, you would need to buy a $16,000, 10 lb. 800mm Nikon lens. A big investment to see that extra quality.

That's not quite true all you've done with a Crop Sensor is Crop the Photo and lose Image Quality.
No way on God's green earth are you going to get anywhere near the quality shots of the Nikon 800mm Lens.

That's the tradeoff with the D7100. If you want maximum sharpness you accept more noise. Here's the cropped only unprocessed shot, without any sharpening.
