The line comprises two camera body models, the ST (Studio) and LT (Lite). The Arricam ST is intended as a full-capability camera, including two camera magazine mounting configurations, whereas the Arricam LT is optimized for smaller, lightweight usage in handheld and Steadicam application, with only the option to mount the magazine in the rear position. Both cameras use motorized displacement magazines, have electronic rotating mirror shutters mounted beneath the film gate (as opposed to beside it, as in Panavision cameras), and contain independently adjustable sprocket pulleys within the camera body.
