記憶卡是送的silicon power 16G class10(卡上寫個十用圓圈環繞，應該是class10吧?)

Continuous Hi mode lets you take about 30 JPEG frames at 6 fps. Thereafter, the framerate falls to about the same as in Lo mode. Once you stop shooting, the camera can theoretically recover very quickly and you should be able to shoot at 6 fps even before all current photos have been written to the card. (In our experience this wasn't true, but that may be down to our older 8gb card.) When shooting RAW, you (ideally) get eight shots at 6 fps before the framerate drops.
