Recently I had to shoot continuous mode and I gained 2 to 3 shots in firing. i.e. RAW maxium 3, where as in jpeg 5 to 6 worked out. Never the less, it is not bad camera to shoot sports unless you want PRO level outcome. Try street shots in sports mode, in continuous firing to see if it helps.
-- my 2 cents
Nope again. I shoot 2500-3500 frames a week with 4 different cameras. Paid work and some times fast shooting. The card makes a difference in clearing the buffer and burst rates. I don't care what the manual or anyone else says.
I agree that the camera is limited to a certain speed (not sure how fast) it can write to the card and no matter how fast the card, that won't improve after a certain point. But if you use a run of the mill slow card and then try a faster one, you will see a big difference and max out the camera's write speed. Plus you have a far more reliable card in use.
I have 6 Class 6 blue Sandisk cards and 5 Extreme III's plus 6 Ultra's, all are 4 Gb capacity. All should be faster than the camera but the Blue class 6 cards are slower to clear the buffer. I have at least 10 older cards that are various slow write speeds and those are painful to use for write times.
To the OP, that card is one I use all the time and it's excellent. I have 6 of them and they are fast and reliable.
