Arca Swiss Reflex
Arca Swiss Reflex cameras are medium- and large-format SLR cameras, made by Arca Swiss from at least the 1950s. They exist in two sizes, for 2¼x3¼-inch (6x9cm) and for 4x5-inch film. The camera has a metal box-shaped body containing a focal-plane shutter, the mirror and the reflex focusing screen, and the front standard on the front of a bellows.
Most examples seen have the rear body and the front standard mounted separately on a substantial monorail, so the camera is a hybrid between a box-form SLR and a monorail camera. In this it resembles the Plaubel Pecoflex, except that the mounting of the rear body allows some movements, whereas the Pecoflex has movements only on the front standard. Some examples of the camera do not have the monorail though, and the lens standard racks out from the body on two much smaller rails at the bottom, like a Fuji GX680 (or continuing the comparison to the Pecoflex, this version of the camera is like choosing a Makiflex instead).
