The Sinar p-slr adapter lets DSLR users attach their camera bodies to Sinar view cameras, and use them as digital backs. This allows superior perspective control, selective focus and focal plane tilting and gives DSLR users an opportunity to use high-resolution digital Rodenstock lenses. The Sinar p-slr can be used with all Canon and Nikon single lens reflex cameras currently on the market. Thanks to the quick locking adapter supplied with the Sinar p-slr, the format can be changed from vertical to horizontal with only a few motions and within seconds. A positioning- and centering aid serves for the exact positioning of the camera on the optical axis. This upgrading set will be available as of August 2010 and it can be ordered right now at the price of 1980 Swiss Francs (not including the Value Added Tax).
