A Digital View Camera Using The Maxxum 7D and Scheimpflug Principle

A gallery showing the invention process from concept through a working model.

The ideas, concepts and design in this gallery are original art and are copyrighted by Pete Ganzel starting December 4 2006.

No part may be copied or used without permission.

The economical Mamiya Sekor 645 lenses have an image circle of approximately 70mm, providing plenty of room for camera movements. Difference in lens registration distance of the medium format lens and the 35mm Minolta body allow approximately 15mm of "swinging room". Rectilinear M645 lenses as wide as 35mm are available.

To compensate for the difference in the "cropped" field of view, splicing of multiple exposures similar to a panorama are planned, the difference being that the lens only is moved instead of rotating the camera. In this way, three overlapping exposures can provide a much wider field of view equivalent to an 18mm lens on a full frame 35mm camera with the M645 35mm wide angle lens.. ...and most importantly, provide perspective correction and optimization of focus planes identical to that of a view camera.
