Canon t3i SD cards

[actorfc]

What is the best SD card to use for shooting video with my t3i canon camera?  Are there cards that are too big?

[ebiggs1]

The best SD card is the ones recommended by Canon in your manual.  The T3i allows SD / SDHC /SDXC cards.

Be guided by the User Manual.  Make certain the card is at least Class 10 for best results.
