Just hooked the free capture app from dslr controller to see if it works.
Works fine with a Galaxsy Tab2 10.1 and a 5d mkII.
Used the cable that came with the 5d and this cable from amazon: Cable
Tried the cheap card reader one and it broke before I could get cables hooked up.
Download the full app tomorrow and start working on a holder for the Tab on my shoulder rig.
Anyone know if Magic Lantern can be used with a separate screen??
