Zacuto, the world leader in electronic viewfinder technology, introduces a new micro-OLED EVF option to their award-winning lineup.

With this unique EVF and Zacuto's trio of powerful Gratical EVFs, there's an EVF for every shooting style.

A Powerful, 1080p Micro-OLED EVF for All Your SDI and HDMI Cameras

The Kameleon EVF, ‘powered by JTZ’, offers unique features like 4K HDMI input downscaled to 1080P, 3D LUTS. With this EVF and our trio of powerful Gratical EVFs, we have an EVF for every shooting style.

The Kameleon differs over the Graticals by offering 4K HDMI input downscaled to 1080P, 3D LUTS and a larger screen with camera data overlayed on the image. The Gratical EVFs have a 16x9 image with space underneath for Vectorscope, Waveform, and Histogram.

The Kameleon has a 4 pin Lemo power jack and a single SDI and HDMI input. The Kameleon is the perfect EVF for Mirrorless and DSLR cameras and it's SDI input adds versatility so that you can use it on a wide variety of other cameras. Like all Zacuto EVFs, It features a built-in -1 to +4 diopter range and Zacuto’s patented essential anti-fog coating formula. It never fogs in humidity or freezing temperatures. An auto-closing eyecup door helps prevent your display from getting burned by the sun.

Overlay and Brightness

The Kameleon EVF overlays camera data over the image, similar to your camera display. This is a great way to quickly get camera data, but it requires lower luminance, 100-125, to prevent OLED burn-in. The Gratical EVFs have a classic 16×9 image with space underneath for information like Vectorscope, Waveform, and Histogram. Moving the data under the image allows for a brighter, more colorful image with a luminance of 150-250, and helps prevent burn-in.

High quality precision optics

The Kameleon EVF includes Red Line Focus Assist to ensure crisp focus. The Gratical EVFs have a few more options with both Red Line Focus Assist, and a Multi-Level Sharpening Focus Assist Peaking, so you can choose the focus assist option
