iDC Photo Video System Zero Viewfinder for the Canon EOS 7D

The iDC System Zero Viewfinder for the Canon EOS 7D helps you better focus images on your Canon DSLR camera's LCD screen. This unit will provide full coverage of your Canon's 3.0" (7.62 cm) display. It also helps reduce glare and shadow on the screen for clear visibility, thanks to the attached Hoodman Loupe 3.0. The viewfinder features a -3 to +3 diopter adjustment.
