Zacuto Gratical HD EVF
ZacutoABOUT THE ZACUTO GRATICAL HD EVF
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. 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 thumbnail.
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.
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 latest anti-fog coating formula. An auto-closing eyecup door prevents sunburn display automatically without any action by the operator.
Mount the Gratical HD to your Next Generation Recoil via the 1/4 20 rosette on the side with an Axis Mini. You can also mount the Gratical HD with the ¼ 20 screw hole in the bottom. Included is the LP-E6 style battery with charger and universal plug adapters.
NEW Gratical X Firmware update 3.4
- OLED will operate natively at 50/60 Hz depending on PAL or NTSC signal received from camera.
- Battery voltage level will be auto-detected and display correct battery level for all 7.2V and 14.4V batteries.
- Zebra stripe settings will be retained after power cycle

Outstanding Quality
The Micro OLED display in the Gratical EVF gives extremely high contrast and true blacks, and superb resolution. When combined with the custom optics, you have a bright, sharp, high contrast image with a generous field of view.
Connections
Includes both SDI in/out and HDMI in/out connections. A neat feature is also the ability to cross-convert HD signal to both HDMI and HD-SDI outputs. For Arri Alexa, Canon C300, Sony F55, and Epic cameras, there will be an optional proprietary cable to supply metadata to match the camera's proprietary EVF information, leaving the SDI / HDMI jack free for other applications such as connecting another monitor
Internal Features
Includes many user aids such as Histogram, Waveform and Vectorscope. You can also move video to the top or bottom of the viewfinder image and customise your readouts around this. This new finder also has LUT creation facility - you can import, create and save LUTS with the option with viewing of your custom settings for example you can preview your preferred settings in the EVF while viewing the RAW image on a separate monitor. You can also customise what data is available in the EVF (eg recording light, histograms) which can be different to that displayed on a client monitor.
Physical Features
Control-wise there are four programmable side-mounted buttons and a full menu joystick and the dioptre adjustment has been re-designed with a range from -1 to +4. Mounting options include a side mounted rosette fitting for either third party mounts or Zacuto's own Access mount, plus a 14"-20 tripod type bush on the bottom. The Gratical uses the familiar Zacuto eyecup design with anti-fog protection and the long runtime battery is removable.
