Cheers Dave and all taken on the D800e for the past year and D700 for a year before that, so I can't agree the you need a DX camera for birds. Or more than 4fps lol
Steve,
I agree with you. You don't need a DX camera for birds. It can be done with FX. But in several years and thousands of frames of shooting DX on wild birds, I have almost never needed to
back up to get my shot. And based on that simple truth, I believe DX is a better
format than FX, if you wanted to design an ideal camera from scratch to shoot birds. And I'll even go so far as to say that the current D800e shooting in DX mode might sometimes slightly surpass what my D7100 can do. But I'm not convinced the D800e in DX mode "crushes" the D7100. I think they are fairly close (except not in price!).
Here are some samples of what I get with my D7100. These are over a year old. I have quite a few newer photos I haven't yet posted. I need to get a new gallery up. Do you think the D800 would have allowed me to do a
lot better than this?
There is an optimal DX resolution that would allow the absolute highest image quality, and I'm not sure what that is. 15MP? 20MP? It might still be changing/developing, and it probably varies depending on the light conditions. I don't usually go out and do bird photography under poor light conditions; I avoid bad light because I'm trying for the best images, and I think the best shots are more likely in good light. I will admit I would have a little more flexibility with those high quality FX sensors. But again, I would almost never use the FX part on birds, only the DX part. Maybe pretty soon Nikon will roll out an FX camera that shoots in DX mode
clearly way better than the D7100. Maybe that time is now; maybe you will convince me. But the price does matter to me, unfortunately. The D810 is expensive. If this new D710 or whatever it is called has a 24MP sensor, will the DX mode hit that optimal resolution?
Finally, I agree with you that you don't need high fps to get great bird photos. Heck, when you get down to it, maybe you don't need more than a D90 to get great bird photos! Once in a while I do get limited by the small buffer in the D7100, or I think maybe a higher frame rate might have allowed me to get "the money shot." So I think high fps and a deep buffer
DO matter, but it's not the main thing keeping me from getting more good shots. Rather, I simply need to get out more often, get more practice and increase my chances for good opportunities. You sure hit those shots of the Red Kite!
