What can I say? It's simple, it works. As you can see it works on the GH2 perfectly without losing view of the entire LCD. Of course it works on the T3i and 60D. The velcro design and stretchy neoprene means it's adjustable to fit a variety of different cameras or even a variety of different view finders. I'm not sure about applying pressure onto the LCD while it's swiveled outwards, but for anyone that has worked outdoors in bright daylight, it's a good way to keep the function of the swivel LCD while acting as a sunshade / VF. $10 dollar tool that folds flat taking up no extra space in the bag. Heck why not. Found via Amazon (Click here)
