The
Canon TS-E 24 mm 3.5L II is a
tilt-shift,
wide-angle prime lens that provides the equivalent of the corresponding
view camera front
movements on
Canon EOS camera bodies. Though it uses Canon's
EF lens mount
The EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it ...

autofocus.
Overview
The TS-E 24 mm 3.5L II lens provides four
degrees of freedom
Degrees of freedom (often abbreviated df or DOF) refers to the number of independent variables or parameters of a thermodynamic system. In various scientific fields, the word "freedom" is used to describe the limits to which physical movement or ...
, allowing ±8.5° tilt with respect to the film or sensor plane and ±12 mm shift with respect to the center of the image area;
each movement can be rotated ±90° about the lens axis.
Shifting allows adjusting the position of the subject in the image area without changing the camera angle; it is often used to avoid convergence of parallel lines, such as when photographing a tall building. Tilting the lens relies on the
Scheimpflug principle to rotate the plane of focus away from parallel to the image plane; this can be used either to have all parts of an inclined subject sharply rendered, or to restrict sharpness to a small part of a scene. Tilting the lens results in a wedge-shaped
depth of field
The depth of field (DOF) is the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image captured with a camera.
Factors affecting depth of field
For cameras that can only focus on one object dist ...
that may be a better fit to some scenes than the depth of field between two parallel planes that results without tilt.
Unlike most view cameras, the shift mechanism allows shifts along only one axis, and the tilt mechanism allows tilts about only one axis; however, the rotation of the mechanisms allows the orientations of the axes to be changed, providing, in effect, combined
tilt
Tilt may refer to:
Music
* Tilt (American band), a punk rock group, formed in 1992
* Tilt (British band), an electronic music group, formed in 1993
* Tilt (Polish band), a rock band, formed in 1979
Albums
* ''Tilt'' (Cozy Powell album), 1981

and
swing
Swing or swinging may refer to:
Apparatus
* Swing (seat), a hanging seat that swings back and forth
* Pendulum, an object that swings
* Russian swing, a swing-like circus apparatus
* Sex swing, a type of harness for sexual intercourse
* Swing rid ...
, and combined
rise/fall and
lateral shift.
In addition to optical improvements, the TS-E 24 mm 3.5L II also introduces a new barrel design, allowing the tilt and the shift to be rotated independently of each other without removing screws on the lens body, as was required on the original version.
Canon announced the second version of this lens on the 18 February 2009.
The lens has been in production since June 2009;
it replaces the TS-E 24mm 3.5L that was introduced in 1991.
