![]() ![]() The space between the two flanges will be filled with the lens-to-camera mount adapter, and the space needs to be adequately large to incorporate both tilting and shifting mechanisms. the distance from the lens mounting flange to the image surface) of the lens is substantially larger than the flange distance of the camera. It is also important that the flange distance (i.e. So, for example, if a four-thirds format camera is used that has an image diagonal of 21.6 mm, it will be necessary to use a lens designed for a larger format, such as the DX format (28.8 mm image circle) or FX format (43.2 mm image circle). In order to take full advantage of tilting and shifting capability, the lens should have an image circle that is substantially larger in diameter than the actual image diagonal. This will allow vertical lines in the object to be perfectly vertical in the image. Adding a shift function to a lens adapter will permit, among other things, the sensor plane to remain parallel to a wall or building while still taking in the full height of the subject. Adding a tilt function to such an adapter will allow a photographer to adjust the plane of focus to meet the Scheimpflug condition in order to increase depth of field, or alternately to intentionally violate the Scheimpflug condition in order to reduce the depth of field. Lens-to-camera mount adapters are used to attach a lens having a relatively large flange distance to a camera having a shorter flange distance. The present disclosure relates to lens-to-camera mount adapters, and more specifically relates to adapters that offer both tilting and shifting functions. ![]() 17, 2011, and which is incorporated by reference herein. 61/383,759, entitled “Tilt shift lens adapter,” filed on Sep. This Application claims the benefit of priority under 35 USC §119(e) of U.S.
