The Shape LCD Viewfinder blocks light and features 3.0x magnification for 3" DSLR LCD screens with a 4:3 aspect ratio. This is useful to check focus and increase stability while shooting video. The viewfinder can also be flipped up and out of the way for use as a simple shade while using the LCD screen.
Additionally, the viewfinder features an adjustable ±3 diopter for matching the view to your vision. It mounts to the camera by gluing the included protective glass adapter to the screen and then snapping on the finder.
