The VF-C300-C500 is a Deity Mira Viewfinder for Canon C300/C300 Mark II/C500 Cameras. This loupe attaches to the camera's 4" LCD screen turning it into a 3x magnification viewfinder. This allows you to both shield the screen and the magnification of the loupe makes it easier to get better focus. This German designed product features a high glass achromatic diopter which provides sharp distortion free 3x magnification. The body of the Mira is made of a high tech aluminium alloy which has an excellent strength to weight ratio, allowing the product to be both lightweight and strong.
