I bought a D7100 yesterday after much deliberation. I've gone through the manual, and have been experimenting. I can't get anywhere near the frame rate for 14 bit RAW that is mentioned on page 58 of the manual(5 fps) - I can get at best 2 or 3 fps. I'm trying to use exposure bracketing with 5 frames at 2.0 EV separation. I'm using shutter speeds of over 1/250, f8, no VR and ISO set at about 1000. Battery full. Is there anything I might be doing wrong? I do a lot of HDR on dark interiors where tripod is not tolerated - so hand - held is necessary. I've gotten along quite well with my D300 so far, but I'm worried the D7100 frame rate may not be up to what I need. Thanks for any suggestions.
Thanks, I've read the thread, but it's my understanding that that only relates to how many shots you get before the frame rate slows. In my case, I can't get to the advertised frame rate at all.( My card is rated at about 30 mb/s) I'm perfectly happy with 5 to 6 frames at 5 fps, and that should be achievable until the buffer is full, but can only get about 3 fps at the best.
Is it re-focusing between frames? As an experiment, try setting AF-S or AF-C, depending on which mode you are using, to Release mode and see if there is a delay in acquiring lock on second and third frames.
Try setting it at factory defaults with the 2 button reset so see if there is a setting that has been overlooked. Use normal CH burst mode, not bracketing, to test.
Thanks for all of the suggestions, everyone - so far nothing has worked. Is anyone else able to get 5 or 6 fps shooting RAW at 14-bit? Either the frame rate is slow on my copy, or the frame rate written in the manual is highly optimistic.
I just tested my d7100 and did a five stop bracket at one stop variation. Yes,I use raw. My time was about one second, best as could tell. My settings for the camera are basically at camera default for most everything.
I only have a D7000 with 3-frame bracketing and while using bracketing with CH it will only take the amount of frames and stop. So at maximum you can only capture 5 frames with the D7100, providing you have the bracketing set for 5 frames. If you only have 3 frames set for bracketing then it will stop after 3.
Perhaps disable bracketing and try CH with 14-bit NEF and see how many frames you can achieve then. My D7000 achieves 6-frames/second even when set to 14-bit raw+fine/JPEG.
