The VGear LCD Viewfinder from Rokinon offers 3x magnification for an LCD screen with a diagonal measurement of 3". It allows you to check critical focus while shooting video or in Live View mode. The viewfinder acts as a shade for your DSLR by blocking sunlight from directly hitting the screen. It also features an adjustable diopter for setting the finder's lens to your vision and an anti-fog lens cover to limit moisture buildup.
The viewfinder features a rubber eyecup for comfort and mounts to the camera via the 1/4"-20 tripod socket found on almost all DSLR cameras. Additionally, the included base plate and eyecup are removable for storage.
