I am still trying to work out what system I should get for shooting action. It may be a FF camera but having previously owned the D5200 I know that the current Nikon's produce superb images.
I had qualified out the D7100 on the basis of its buffer but I just found this, and wanted to ask if it is correct or not?
"If you shoot 14-bit lossless compressed RAW, the bufffer is a measly 6 images large. At the camera’s native frame rate, that’s just 1 second of shooting before the buffer slows.
However, turn the D7100′s RAW quality down to 12-bit and true (lossy) compressed, you get a good 9 frames in before the camera slows down. Then, jump to 1.3x (total 2x) crop mode, and you get a good solid 10-11 frames (at 7 FPS!) before the buffer fills."
I expect to shoot action in crop mode and presumably 12 vs 14 bit doesn't make any real difference? In which case 10 images in the buffer is more than enough!
