 The Portkeys BM5 III WR Monitor  is a robust 5.5-inch on-camera monitor ready for all your next creative adventures thanks to its compact form factor, daylight-viewable touchscreen, four user function buttons, a full suite of professional monitoring tools, and the capability to control your camera.

The housing of the BM5 III is entirely made of rugged aluminum and has toughened glass in front of the display. However, with a weight of only 351g/12.3oz (without battery), you’ll easily forget it on your camera rig.

With a high brightness of 2,200 nits, shooting outside in bright sunlight is no longer a problem. Each BM5 III WLED display is factory color-calibrated and passes strict hardware controls to ensure the most accurate colors. In addition, the 10-bit (8+2 FRC) panel makes color reproduction more accurate with a rich level of color details and no color banding. This 5.5-inch monitor has a FullHD 1920 x 1080 resolution, a large 178° viewing angle, and a 1000:1 contrast ratio.
