It appears that after firing around 8 to 10 shots, the buffer in the camera appears to be full and struggling to take in more shots. Ex. When football team first comes out, I can only get a few players coming towards me and can only then get just a few shots (maybe 4+ shots) of cheerleaders because the buffer is apparently full and/or the card is still writing. I already checked the max (130) allowed for the buffer. I must be missing something or the cards I'm using are just too slow, although I did use the sandisk III on the MK III with no problems. I am new to Nikon and could very well be missing something here. I can expect that kind of performance while using tiff or raw files, but I only use just jpeg files from fine to normal size. I've had the MKIII and noticed that the buffer rate of canon's is by far much better, but wondered if I am doing something wrong. I tried to turn off the D-Active lighting and high ISO noise filter and nothing seems to change. I do however use the sandisk extreme III 16gig & Ridata 16gig 233x cards, but either one is just as slow as the other. I have already heard about the $400/500 upgrade, but not interested in spending more money. Any comments or solutions.
