The Red DSMC L-Plate Package is part of an Arca-Swiss-type quick-release system for Red DSMC and Red DSMC2 cameras (Weapon, Epic , Scarlet-W, Scarlet, and Raven).
Red's DSMC cameras are unusual in the cine market for their ability to function in extremely compact configurations ideal for small-crew/no-crew cinematography and even for still photography. In those configurations, large heads using broad "Arri-standard" dovetails are less desirable than much more compact ball, pan/tilt, geared, gimbal, fluid, and other heads which use Arca-Swiss-type dovetails.
The Red DSMC L-Plate Package includes the Red DSMC Landscape Dovetails (landscape-orientation dovetails aligned with the camera's optical axis and a removeable 15LW rod bridge at industry-standard height) and the Red DSMC Portrait Dovetails (portrait orientation dovetails aligned with the camera's optical axis). This package is a $25 discount.
Unlike most Arca-Swiss-type quick-release plates, the DSMC L-Plate can rest on a flat surface because its safety stop pins are retractable (spring-loaded).
The plate's "capturing" threads are recessed from the mating surface to minimize cross-threading.
Note: portrait-orientation dovetails intended to support the DSMC only in lightweight (primarily stills) configurations, please be conservative
Note: rods are shown for illustrative purposes only and are not included
Note: compatible with either v1 and v2 front fans
Note: officially confirmed by Red not to interfere with the camera's warranty
