Is there a required speed and size SD card needed for the C300?

I think you mean CF cards. Some info in this thread....

No, Andy I do mean SD cards I have a huge supple of CF cards from my Nano that I will use for the camera.

The camera also takes a SD card for file transfer and store profiles. I am checking to make sure I buy the right speed and size. I can not find info on the size and speed needed for the SD cards.

Ahh OK! You learn something new every day...

No worry that is why we are on DVinfo.

I know the SD cards are cheap but I am not sure how much space or speed is needed for the Picture Profiles. I think that is all the card is used for but could be wrong.

I bought an Eye-fi pro 8gb so I could send frame grabs to my iPhone in real time. This allows me to get almost instant photos to Facebook or Twitter.

Brett thanks.

I will go with Sandisk Extreme 8GB.
