Gratical HD EVF

Bright. Sharp. Brilliant.

Over two years in the making, Zacuto brought five different engineering companies together to create the Gratical EVF, a new electronic viewfinder concept. Electronic viewfinders are a pivotal tool in any filmmakers bag, providing accessibility, stability, focusability and so much more. Unlike a standard electronic viewfinder, with the Gratical HD EVF and Gratical X EVF, you can trust you’re seeing a realistic visualization of your final image. The processing power and sharpness of the Zacuto Gratical electronic viewfinder far surpasses all other EVF units on the market.

Zacuto offers two Gratical EVF options; the Gratical HD and the Gratical X. Both units start with a 5.4 million pixel micro-OLED display, high quality precision optics with a built in diopter, and a powerful FPGA dual core processor. The models differ only in software. The Gratical HD EVF comes packed with professional features like Vectorscope, Waveform (3D), Histogram, LUT import and creation and much more. The Gratical X EVF includes only basic features and our unique, customization program allows you to build the software package that’s right for you.

About the Gratical EVF

Micro-OLED EVF Display

The Gratical EVF has 5.4 million pixels on a 0.61” diagonal screen no bigger than the size of your thumbnail. This EVF supports high pixel density with unparalleled resolution, true blacks, gamma and contrast range. With Micro-OLED screens, each pixel is lit individually so that when one is turned off there is true black. This makes for a wider contrast range and more vibrant colors for a vivid, enhanced picture. And with a full display electronic viewfinder resolution of 1280×1024 you know you’re getting the best picture possible.

Zacuto Gratical HD EVF HDMI and SDI connections


The Gratical EVF includes HDMI and SDI inputs. HDMI and SDI outputs, and cross conversion comes standard with the Gratical HD and are optional features with the Gratical X. Weather resistant covers prevent moisture or debris from getting in open ports. Physical connections include both a ¼ 20 screw hole underneath the EVF and a rosette on the side. Attach your electronic viewfinder with an arm or Zacuto Axis Mini as part of a Zacuto Next Generation Recoil Rig.

High Quality
Precision Optics

You’ll be amazed with how sharp this EVF 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.
