Zacuto Gratical Eye


Photo Pro Video


Product code: Z-GRE

The Gratical Eye SDI electronic viewfinder is the smallest and lightest Zacuto Micro-OLED EVFs. This is an ideal SDI EVF solution for filmmakers using professional cameras and external batteries. It has a 2 pin Lemo power jack and a single SDI input, and fits in the palm of your hand.Sleek and small, this EVF will fit in even the smallest of camera bags. Take it with you on the road or add it to your studio rig.

When used 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 sensor. If the sensor does not detect anything for 7 seconds (time is user adjustable) the screen will go black and then wake up instantly when it detects motion. After 1 hour of being idle, the Eye will go into auto shutoff mode, saving you power.
