This MID49 Side Plate for Blackmagic PYXIS mounts on the side of your camera, providing additional accessory mounting points and an ARRI-compatible rosette. The rosette enables mounting optional handgrips. The 1/4"-20 and 3/8"-16 threaded holes have ARRI-compatible anti-twist divots to help prevent your mounted accessories from twisting. There are marked 3/8"-16 and 1/4"-20 holes on the sensor axis, and the plate is the correct thickness to mount the camera vertically on an optional Baseline 15mm LW (Blackmagic PYXIS), which creates the correct lens center-to-15mm rod height for lens accessories. A select (painted/striped) 1/4"-20 provides an ideal mounting location for Audio Breakout AB-9 (Blackmagic PYXIS) and recessed cable loops on the back of the side plate allow for clean cable management.
