A:AnswerYes, you could use but I would use something with a faster read/write speed, like the Extreme by SanDisk. The R/W speed is 80/50MB/s speed vs 30MB/s. In fact, I use Extreme SDcards in my Nikon camera and Sony HD video camera.
A:AnswerThe 4 inside a circle represents Class 4 however since the listing on the website specifies that it is a Class 2 card you may recieve a Class 2 on the purchase of the product. It seems that the picture updated is incorrect.
A:AnswerHELLO, SCARLETT. SURE, I WOULD RECOMMEND THIS 8GB MEMORY CARD FOR YOUR CANON POWERSHOT CAMERA. HOWEVER, HIGH-DEFINITION DATA, WHICH PICS AND VIDS COMMONLY ARE, QUICKLY USE LOADS OF DATA, SO I'D ACTUALLY RECOMMEND A CARD WITH MUCH LARGER CAPACITY. HOPE THIS HELPS YOU. GOOD LUCK AND ENJOY!!!
