The Rollei T2 Adapter to Adapt SLR Cameras to the X-Act Camera - With a commercial T2 adapter, practically any analog or digital 35mm-based SLR camera can be mounted on the rear standard. And, format orientation is a cinch - The camera attached to the standard can be rotated quickly and easily to either vertical or horizontal format.
A combination of X-Act and SLR or DSLR camera can be used with different lenses. In conjunction with a large-format lens, however, full use can be made of the camera movements of the X-Act. This lets you shoot pictures you could not or only with difficulty take with an outfit based on 35mm camera bodies.
Architectural photographers thus are able to shoot even high buildings without converging verticals, table-top specialists will make the plane of best focus coincide with the requirements of their subject - or do just the opposite to focus the viewer's attention precisely on a small detail.
