The Gratical HD EVF is Zacuto’s flagship model – the original! Feature rich, versatile, future-proof, and time tested, the Gratical HD is the ultimate choice for the consummate professional. Designed to fit smoothly into a filmmaker’s workflow both on-the-go and in the studio. The Gratical HD Micro-OLED EVF offers a full suite of power, mounting, inputs/outputs, and feature options. If you’re looking for a one-stop product to cover all your current and future needs, the Gratical HD is the model for you.
As with all our Gratical electronic viewfinder models, the Gratical HD starts 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. Find out more with our full spec breakdown below.
The Gratical HD features a built in -1 to 4 diopter range and Zacuto’s patented anti-fog 2 level system. Level 1 – the custom lens is coated in an anti-fog formula. Need even more protection? Move on to level 2 – add the included clear anti-fog disc over the existing lens for double protection. Never fog up your lens again in rain, shine, indoors and outdoors. You won’t realize how much of a lifesaver this is untill you’ve used it! Zacuto Graticals are the only EVFs to offer this essential feature. Tested from a freezer straight to use outside on a hot humid day – and it never fogs. An auto-closing eyecup door prevents sunburn display automaticly without any action by the operator.
The Gratical HD is powered by a state-of-the-art FPGA dual core processor that supports a host of professional features including HDMI and SDI with simultaneous cross-conversion, Vectorscope, Waveform (3D), Histogram, Timecode, LUT import, creating, and editing, and more. (See full feature list below.) The processing power of the Zacuto Gratical HD far surpasses all other EVF units on the market.
The built-in USB port is used for downloading firmware updates and additions. Gratical HD users have access to all future updates and additions free of charge for life. We are constantly working on improving workability of current features and creating new features to keep your EVF up to date and future proof.
Power & Mounting
Self powered with an included LP-E6 battery, the Gratical HD has a run time of about 4 hours. You can also use a LP-E6 to d-tap cable (like this one) and power the unit off system batteries for a much longer run time. Mounting options include both a ¼ 20 screw hole underneath the EVF and a ¼ 20 rosette on the side. Attach your electronic viewfinder with an arm or Zacuto Axis Mini as part of a Zacuto Next Generation Recoil Rig.
The Gratical HD has a Zacuto designed Micro-OLED 0.61” diagonal display with 5.4 million pixels to provide a hugely expanded 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.
Connections & Compability
Incorporates an HD-SDI input and output and an HDMI input and output with weather resistant covers to prevent moisture or debris from getting in the open ports.
