SmallHD Focus 504

The SmallHD Focus 504 is a 5-inch on-camera monitor aimed at light handheld rigs and mobile productions. Its anodized aluminium unibody weighs 310 grams without a battery and measures 136 × 88 × 23.9 mm, close to the footprint of a large phone.

The panel is a 4.97-inch IPS LCD touchscreen at 1920 × 1080, 443 pixels per inch, 1000 nits of brightness and 100% Rec.709 coverage. For signal it carries 3G-SDI and HDMI 2.0 in and out, with cross conversion in both directions, so an SDI feed can go out over HDMI and the other way round. The touch layer keeps the menus reachable with a tap, which helps when the monitor sits above the lens.

Power accepts an L-Series battery on the built-in plate, a 10–17 V locking 2-pin input or USB-C. The monitor adds three locking USB-C ports, 1/4"-20 threads on all four sides with ARRI locating pins, 2.4 GHz Wi-Fi and the PageOS 6 system, with customisable pages, exposure and focus tools, and LUT loading from a USB drive.

Camera control for RED, Sony, ARRI and Canon bodies is enabled through licences sold separately. With those credentials, the SmallHD Focus 504 targets operators who need SDI, a bright panel and monitoring tools in a compact body, rather than anyone after a cheap HDMI-only display.
