You can also look into Zacuto Kameleon EVF as an option or check for availability of USED units on Zacuto eBay store.
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. Zacuto 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. Technical Specifications:
