Description
The Alphatron Broadcast Electronics EVF-035W-3G Electronic Viewfinder features a 3.54″ LED-backlit LCD and displays 24-bit RGB at 960 x 640 resolution in a 16:9 aspect ratio. Brightness is at 500 nit and contrast ratio at 1000:1. The viewing angle is 160 x 160°. The unit comes equipped with an adjustable diopter and a manual lens shutter for protection of the LCD. A 6″ D-tap cable is included.
Connections consist of SDI and mini-HDMI inputs and outputs, a phone jack for calibration and a USB port for software upgrades. You can loop out from both SDI and HDMI and perform conversion out from HDMI to SDI. (If your camera has a mini-HDMI port, like many cameras do, then you will need a mini-HDMI to mini-HDMI cable to connect the camera to this viewfinder.)
Adjustable features include Brightness, Contrast, Color Temperature, Sharpness, various Scan modes, Markers, User Aspect Zoom, and Blue Gun. Professional features available are 3G Level A/B, Audio Meter, Time Code, Range Error, Zebra, Luma y’ Zone Check, Focus Assist, and Internal Colorbar and Pluge Pattern.
The viewfinder has a lightweight magnesium housing and can be powered by an optional battery or DC power supply.

⚠️ Important Disclaimer on Runtimes The runtimes provided above are estimates only, based on standard mathematical calculations. Your actual runtime may vary depending on several factors, including the age and health condition of the battery, environmental temperature, active cross-conversion (HDMI to SDI), and screen brightness settings. Because EVFs are constantly pressed up against the eye, utilizing the built-in manual shutter when not in use can help save power and protect the screen.
