Leica R EOS MC Arsat (Photex) 2,8/35 Tilt and Shift (TS PC) Lens

Remarks

The TS 35mm f/2.8 makes a tremendously important contribution to the versatility of the Leica R 35mm system of photography. It enables the photographer to obtain results with a 35mm camera that normally require the use of a large format view camera with its swings and tilts. With the TS 35mm the photographer creates technically correct images of both studio and architectural subjects. Perspective and depth of field can be controlled to a much greater extent than is possible with conventional lenses.
Correcting Perspective with the Tilt/Shift Lens
If you photograph architectural subjects with a conventional wideangle lens aimed up at the building, perspective in the photograph looks unnatural. Lines converge and the building appears to be leaning backwards because the subject and film plane are not parallel to each other. The TS lens provides a solution to the problem. Shifting the lens allows desired framing while keeping the film plane and subject parallel. This also eliminates unnecessary foreground in the process, improving overall composition. This shifting ability can also be used for photographing images in a mirror or window thereby excluding the photographer's reflection.
 The tilt mechanism allows you to control overall image sharpness. Used in conjunction with aperture, the tilt feature of this lens gives you tremendous depth of field control. This is especially helpful when shooting an object at an oblique angle. For example, let's assume you want absolut~ sharpness in the foreground and background of a still life scene. First focus on the closest foreground object then tilt the lens until the background also comes into focus. You then make minor focus adjustments, close down the lens to the desired aperture and shoot. Using the tilting mechanism provides an additional means of controlling depth of field and thus allows greater freedom over the aperture and shutter speed combination.
 Suppose you want to shoot a long building at an angle with all of it in the best possible focus. Due to the angle between the building and the film plane, foreground and background cannot be rendered sharp simultaneously. Here's where the Scheimpflug principle on which the solution is based comes into play. Imaginary lines must be drawn parallel to the front of the lens and the film plane and a third line from the subject. To attain maximum depth of field, the lens must be tilted so all the lines meet at a point in space. Tilting the lens brings the third line to the point of intersection, increasing the range of sharp focus.
 Conversely, suppose you want to focus on only certain objects in the middle of a scene, throwing everything else out of focus. In this case focus and tilt the lens so that the subjects are all in the same plane and are parallel. This technique is especially helpful when photographing a product or still life, using the shallow depth of field to emphasize only the central subject. The TS lens could be portraying as a problem solver but it is also capable of taking the images that may challenge your creativity with its optical characteristic.
The direction of the shift can be changed 360 degree and locks at 12 angles.
