Product information

Over two years in the making, Zacuto brought five different engineering companies together to bring this newest EVF concept to life. The Gratical HD 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.

Key Features:

Micro-OLED Display
Our Micro-OLED display supports high pixel density with unparalleled resolution, true blacks, gamma and contrast range. The Gratical HD has 5.4 million pixels on a 0.61" diagonal screen no bigger than the size of your pinkie fingernail.

The Gratical HD includes two HDMI and two SDI ports with cross conversion from HDMI to SDI. Weather resistant covers prevent moisture or debris from getting in open ports.
High Quality - Precision Optics
You'll be amazed with how sharp the image is. The internal field of view is larger than most of the competition and features a built in -1 to +4 diopter range and Zacuto formula anti-fog coating. Auto-closing eyecup door prevents display sunburn.
