The Gratical Eye SDI electronic viewfinder is the smallest and lightest of our Micro OLED EVFs. It fits in the palm of your hand and weighs only 14oz. This is an ideal SDI EVF solution for filmmakers using professional cameras and external batteries. The Gratical Eye has a 2 pin Lemo power jack and a single SDI input. A 75Wh battery can power the Gratical Eye for 14 hours! Mount the Gratical Eye to your Next Generation Recoil via the 1/4 20 rosette on the side with an Axis Mini. 

The Gratical Eye Micro OLED electronic viewfinder uses an extremely powerful FPGA dual-core processor and the latest Micro-OLED displays to provide a hugely expanded contrast range. Our Micro-OLED display supports high pixel density with unparalleled resolution, true blacks, gamma and contrast range. The Gratical Eye has 5.4 million pixels on a 0.61” diagonal screen no bigger than the size of your thumbnail.

You’ll be amazed with how sharp the image is. The internal field of view is just the right size so that the image is large, but not so that your eye has to roam to see the entire image at once. It features a built in -1 to +4 diopter range and Zacuto’s patented essential anti-fog coating formula. It never fogs in humidity or freezing temperatures. An auto-closing eyecup door prevents sunburn display automatically without any action by the operator.

Along with the full suite of Zacuto EVF firmware (full scopes, LUTs, multi level peaking, and more), the Gratical Eye has two unique features - an external tally light and a proximity screen saver.
