its just kind of to fuck around on; im using a different sd camera to transfer footage etc so i dont fuck up the heads; and the opteka extreme fisheye thing for 60 bucks http://www.amazon.com/Opteka-X-TREM...d=1424655135&sr=8-1&keywords=canon+gl+fisheyeI've had 3, I really love the footage these things come out with. Just a heads up about buying an sd cam, don't just try to buy the cheapest one you can find. Find one that you know is in prime condition or you'll regret it once the thing dies and you end up spending even more money on a second one. What kind of fisheye are you getting for it?
