For years, bellows systems have been used successfully by still photographers to manipulate depth of field and perspective, for more accurate representation of shapes and products.

The shift feature provides greater range to shoot around objects and can even help avoid camera reflections in a mirror. The tilt feature allows changes in the angle of the plane of focus. This angling allows for an increase or decrease in apparent focus.  The bellows allows for macro cinematography.

The bellows unit is particularly robust and precise. The color coded adjustments are very smooth so they can be changed during the shot. All adjustments are carried out via transmissions. An index scale facilitates the exact duplication of chosen settings. The focusing knob features a white marking disk on which focus positions can be individually marked, as well as a connection for mechanical remote controls.

The lenses were specifically designed for this application. The bayonet mount facilitates quick lens changes. The double aperture scales, located opposite each other, are calibrated in T-stops and are easily readable from the side. Uniform design, a consistent front diameter of 87 mm and the geared iris ring offer further user-comfort. The system can be used with both 35 and 16 mm cameras.

Accessories include a PL mount (allows the use of standard PL mount lenses, especially interesting when using the ARRI Macros) and a motorized focus (CFM-1) that can be operated wired or wireless. Like all other ARRI products, the Shift & Tilt System is well constructed and robust.

 

Angles of Movement:

Shift	Perspective correction Eliminating perspective distortion in architectural photography Moving the image (framing) without changing the camera position. This allows, for instance, shooting "around" unwanted objects. Avoiding unwanted reflections. Example: mirror, shop window Excluding unwanted objects in the foreground Changing framing without moving the camera
Tilt	Alter the focus plane, giving more or less apparent depth of field. 2 shot in car Foreground out of focus Isolating a particular subject area with a specifically chosen focus plane
Bellows	Macro capabilities Since there is little depth of field when shooting macro shots, the tilt function allows small objects that are at an angle to the film plane to be completely in focus.
