The LD View Camera for Canon EOS is a view camera equipped to immediately accept Canon SLR cameras, allowing users easy control of depth of field, distortion, lateral shift, portrait/landscape orientation, and more. You must use a large format lens or a medium format SLR lens made for Pentax, Hasselblad, or Mamiya cameras.
You'll have more creative control over the image than would be possible with any EOS-type SLR lens attached directly to your Canon EOS camera-including Canon's TS-E series. Control perspective distortion by tilting the lens standard or body standard (focus plane), or use lateral shifts to move the image upon the ground glass and get larger image stitching. In addition, you can change format very quickly and smoothly.
The Horseman LD's unique ability to take advantage of camera movements such as shift and tilt is beyond the scope of a normal EOS SLR. It provides a swing/tilt of up to 360 degree, a rise/fall of 30mm each and a lateral shift of 30mm left and right. With conventional view cameras without the LD's unique focus-plane-axis tilting, you get focus and image shifts with tilts, which require refocusing and recomposition. No image or focus shift occurs when using the LD's rear tilt/swing, allowing you to control the plane of focus by tilting the lens.
This LD also has the optional capacity to take advantage of high-end digital back made for medium format cameras, from companies such as Phase One, Leaf, Imacon and Sinar, or to convert to a 4x5 film camera. Hasselblad "H", or Mamiya 645 back.
