Portkeys LH5P III

The Portkeys LH5P III monitor is a lightweight 5.7-inch touchscreen on-camera monitor that also lets you control your camera directly from the screen. Portkeys announced it in September 2026, after showing it at NAB and IBC. It weighs just 235 g, 18% less than its predecessor, so it won’t weigh down a gimbal or a light rig. It is a great choice for operators working with mirrorless and compact cinema cameras.

A bright 2200-nit screen

The 2160 x 1080 screen with 2200 nits of brightness stays readable even in full sun. Thanks to the wide panel, a Full HD image fits on screen in full, with information and tools shown beside the frame rather than over the picture. The monitor processes the image in 10-bit and comes factory calibrated with Calman, so colours on the preview are reliable. It accepts HDMI up to 4K DCI 60p and has an HDMI output to pass the signal on, for example to a wireless video transmitter.

Camera control from the screen

The biggest advantage of the LH5P III is camera control, wired or over Wi-Fi. From the monitor’s screen you can start recording and adjust aperture, shutter speed, ISO, white balance and more, and on selected Sony cameras, such as the FX3 and A7S III, you can set the focus point by touch. Supported cameras include Sony models (FX3, FX30, FX6, FX5, A7S III, A7 V and more), Canon (C50, C80, R5 II and more), Nikon (ZR, Z8, Z9), Panasonic and Blackmagic Pocket 4K/6K. The short 2-in-1 cable in the kit carries both HDMI video and USB-C control.

Exposure tools and LUTs

You get RGB and luma waveform, histogram, zebras, false colour (including an ARRI mode), focus peaking and the new LOG STOPS tool, which shows exposure in stops based on the camera’s Log profile. The monitor supports anamorphic desqueeze (including 1.33x, 1.5x, 1.8x and 2.0x), frame guides and grids. You can load up to 20 custom 3D LUTs from a USB stick via the USB-A port. Four programmable buttons and a scroll wheel give you quick access to your favourite functions.

Power and a complete kit

The monitor draws about 13 W and runs on an NP-F battery or via USB-C PD, for example from a power bank or a V-mount battery. The aluminium housing is just 28.4 mm thick. Our kit comes with two NP-F batteries and a charger, a small magic arm for mounting on the camera, a micro HDMI adapter, an antenna, plus a protective case and carrying bag, so there is nothing extra to sort out.
