The Cineroid EVF4CHE Electronic Viewfinder with HDMI Input / Loop-Through Output offers an eyepiece view or an LCD view. The eyepiece/optical loupe can be flipped up out of the way much like a traditional ENG viewfinder, or detached completely to reveal a 3.2" LCD with an 800 x 480 resolution. A built-in adjustable diopter and removable extension frame allows you to use the EVF even without having perfect eyesight.
The HDMI input and loop-through HDMI output allows you to feed the EVF, and send the unmodified signal downstream to an optional director's viewfinder, video village, or other display / recorder. The EVF supports a variety of focus and exposure tools, including two forms of peaking, false color, crop guide, pixel-to-pixel mapping, and image flip. A headphone jack and built-in speaker allow you to monitor audio, and a 1/4"-20 threaded mounting hole allows you to mount the EVF to your camera using optional articulating arms. The EVF4CHE is powered by optional Cannon LP-E6 batteries, or from an optional external power supply, that provides 6 to 17 VDC. The USB port is for firmware updates.
