I just got a canon, t3i, still trying to figure it out, and haven't posted from it yet as I keep forgetting my eye fi card. If you want to download photos from your camera to mw or social sites while in the parks, without a laptop or tablet, you will need the eye fi card, it is a memory card in your phone that automatically sends the photos to your phone so you can download then. some of the newest cameras not have that built in but the t3i does not. some of the better photographers on here will give you tips or look it up under search for an old post. have fun with it!:) - secretagentangel  670.2 #154 7:22PM

There was a post about this a while back. I'll find it for you and bump it. There was a lot of good info on cameras from fellow MWers. - ZeeAlice  470.7 #258 1:11PM
