The Portkeys LEYE 3G-SDI & HDMI 2.4" LCD Electronic Viewfinder expands upon the capabilities of the previous model by adding a 3G-SDI input and an integrated LP-E6 battery plate to the interface. The 3G-SDI input supports up to 1080p video, while the HDMI input supports up to UHD 4K. This viewfinder features a 2.4" LCD screen with 1440 x 900 resolution, 450 cd/m² brightness, and 1100:1 contrast for viewing images clearly in bright conditions. A round sponge eye mask further ensures viewability by preventing direct sunlight from burning the LCD screen.

Several mounting options are integrated into the viewfinder for attachment to your camera rig configuration: a rosette, three 1/4"-20 threads, and a NATO rail. Various video assist functions can be enabled to monitor the quality of your image, and a -3 to +8 diopter range allows you to adjust focus to comfortably suit your vision. Power for the device, when not provided with an LP-E6 compatible battery or power bank, can also be achieved with the self-locking 4-pin aviation connector input. You can upload custom 3D LUTs of your choice to the viewfinder or upgrade the firmware using the USB Type-A input.
