Let me rephrase that. Right now I've been using 2GB SanDisc Ultra II 15MB/s SD cards. They seem to do alright but are getting a little long in the tooth.
Could I upgrade to SanDisk EXTREME 8GB 30MB/s 200 SDHC cards or would they too fast for the camera to use efficiently?
Would I be better off with something slower? Could the GXR handle anything quicker (or bigger, or smaller) etc...
Thanks again and all the best,
Irenaeus
