The EVF is HDMI out so a low res on the 5DMKII as they cripple the Full HD out and a little better on the 7D and other DSLR cameras that have a better to full res HDMI out.
The Redrock Micro EVF is self powered by standard batteries and can run for around 10 to 12 hours.
So what is the difference between having a EVF or a Monitor coming out via HDMI? A so called “Game Changer” Their words: you decide for $595.

Do the numbers add up: 1.2m total dots: Key is Total Dots: It’s 1,245,816 total dots resolution & that’s 858×484 x 3 R, G, B so to be higher than RED Bomb EVF needs to be 1280×720 x 3 = 2,764,800 total dots resolution

Redrock Micro Press release:

Redrock Micro, the recognized leader in affordable professional-quality cinema accessories, today announced the new patent-pending Redrock microEVF electronic viewfinder for HDSLR cameras. This is the first electronic viewfinder designed from the ground up specifically for HDSLRs, emphasizing compact lightweight design, superior resolution, and incredible affordability.

The popularity of HDSLRs such as the Canon 5D MKII for video and motion photography has skyrocketed in recent years, but the camera body is not ideal for video. The first generation of solutions for monitoring currently available –attaching an optical viewfinder to the back of the camera’s LCD screen –severely limit placement of the viewfinder and camera body and eliminate possibility of using additional monitors for camera assistants or directors. The new Redrock microEVF is an external electronic viewfinder that connects to the camera body and can be placed anywhere for maximum comfort and stability, and can be part of a multi-monitor solution. The microEVF uses a custom made state-of-the-art backlit LED fitted in an attractive, ergonomic housing.


Key features of the microEVF include:

* A full color HD viewfinder designed specifically for the compact, lightweight needs of HDSLR cameras. The microEVF weighs in at less than 6oz.
* Ultra-high resolution 1.2m dot display that is higher resolution than the Canon EOS cameras’ rear LCD
* LED backlight maintains bright crisp picture with minimal power consumption
* Electronic assist features that will be announced closer to production release
* Infinitely configurable mounting options to position the microEVF exactly where desired
* Low power consumption delivers a full day’s continuous viewing with a self-contained battery

“We feel it’s time for a better approach to HDSLR camera monitoring,” said James Hurd, Chief Revolutionary for Redrock Micro. “The microEVF meets this need with an elegantly designed, compact solution that is not only affordable, but also sets a high standard for features and performance.”

The microEVF also compliments advanced camera crews by working alongside external monitors, such as a monitor for the assistant cameraman, and one for a director or video village. The microEVF is compatible with any HDSLR or video camera that provides HDMI output while recording. HDSLR cameras known to be compatible include the Canon 5D MKII, Canon 7D, Canon 60D, Canon T2i, Canon 1D MKIV, Nikon D3s, Nikon D300s, D3100, and D7000.
