| Canon TS-E 45 mm f/2.8 Tilt/Shift LensContents
IntroductionDescriptionThe TS-E 45 mm f/2.8 lens provides image controls similar to those provided by view camera movements. The tilt allows control of the plane of focus to maximize or minimize the depth of field (DOF); the shift allows control of apparent perspective. The 45 mm focal length gives a natural perspective useful in product and landscape photography. By placing the camera close to a foreground object, a near/far effect often can be achieved while getting the entire scene in acceptably sharp focus. The lens is also useful for architectural photography in which a slightly more distant vantage point gives a more natural depiction of the relationship between features, especially with traditional architecture. Features
Note: As supplied, the tilt and shift operate at “right angles” to each other, so that it is possible to combine tilt and lateral shift or swing and rise/fall, but not tilt and rise/fall or swing and lateral shift. The lens can be modified by a Canon Service Center so that tilt and shift operate in “parallel”, allowing combined tilt and rise/fall or swing and lateral shift. Refer to the article on Image Controls for a description of camera movements. NomenclatureControls

OperationMounting the Lens
Note: Whenever practical, attach the lens hood to prevent flare and protect the front element of the lens, especially when the lens is used without a protective filter. Removing the Lens
Caution: Do not rest the lens on the camera mount—damage can occur to the delicate electronic contacts. Attaching the Lens Hood
Removing the Lens Hood
Note: Before storing the lens, attach the front lens cap to protect the front element of the lens. If desired, reverse the lens hood and attach it to the front of the lens in the same manner as for attaching the hood. FocusingAutofocusNot availableManual FocusWith the tilt and shift set to zero, look through the camera viewfinder at the subject, then rotate the manual focusing ring on the lens until you see the viewfinder image is as sharp as possible. If you manually focus while holding the shutter release button depressed halfway, the focus sensors in the camera may indicate in the viewfinder when sharp focus is detected in a focusing zone. Setting the ApertureThis lens has a stepping-motor–driven electromagnetic diaphragm (EMD). The aperture is set and controlled electronically from the camera body. Operation is fully automatic in the same manner as with a normal EF lens. ExposureAll metering patterns and all automatic exposure (AE) modes except for DEP can be used in the same manner as with normal lenses when the tilt and shift are set to zero. However, exposure measurements made with the camera’s TTL metering system when the tilt and shift are not zero will be in error, and the magnitude of the error will depend on the amounts of tilt and shift. It’s usually difficult to make an exposure measurement using one of the camera’s AE modes and then set the tilt or shift or both while keeping the shutter release depressed halfway, especially when using a tripod. Manual exposure usually is a better choice when employing tilt or shift. Use of an external meter allows exposure measurements to be taken after tilt or shift have been set, which can be very helpful in conditions of changing lighting Setting Tilt and ShiftWhenever possible, use a tripod with the TS-E 45 mm f/2.8 lens. A small change in camera orientation can cause a large change in the orientation of the plane of focus, and can have considerable effect on convergence of parallel lines. A focusing screen with a grid, if one is available for your camera body, may be helpful in maintaining alignment of vertical or horizontal lines when shifting. A bubble level that attaches to the camera’s hot shoe can help ensure that the camera is precisely level Tilt
Note: In many situations, setting the proper tilt requires considerable experience. Refer to the article on Image Controls for a description of several possible approaches. Shift
The TS-E 45 mm f/2.8 lens can be rotated about the lens axis up to ± 90° to provide the same effect as combined rise (or fall) and shift, or combined swing and tilt. Detents are provided every 30°, and locks at the 90° positions. To rotate the lens, press the lock release lever on the right side of the lens. Be careful to avoid hitting the finger used to press the lock release lever, especially if the shift or tilt is not set to zero. Lens CareStorageUse the front and rear lens caps to protect the lens. Store the lens in a cool dry place, out of direct sunlight. The lens has moving parts that are sensitive to dust, and the shift and tilt mechanisms have additional openings through which dust can enter. When working in a dusty environment, clean the lens body with a blower or soft brush, and keep the lens in its case or a closed camera bag whenever possible. ServiceThere are no user-serviceable parts inside. Contact the nearest authorized Canon Service Center AccessoriesFront AccessoriesClose-Up LensThe TS-E 45 mm f/2.8 lens can be used with a 72 mm Canon 500 or 500D close-up lens to achieve magnifications up to 0.25, although vignetting can occur if the lens is tilted or shifted. Rear AccessoriesEF extendersThe TS-E 45 mm f/2.8 lens is physically compatible with Canon EF 1.4x and EF 2x extenders, although Canon do not officially endorse their use. When a TS-E lens is used with a Canon extender, the presence of the extender is not communicated to the camera body, so the displayed f-number is incorrect. The error is 1 step with the 1.4x extender, and 2 steps with the 2x extender. For example, with the 1.4x extender, indicated f/5.6 is actually f/8. Readings with an external meter, or use of a “rule” such as the “sunny 16” (f/16 @ 1/ISO), will require compensation. For example, with ISO 100 film, one possible exposure with the “sunny 16” rule is f/8 @ 1/400 second; if the TS-E 45 mm lens is used with the EF 1.4x extender, the camera must be set to f/5.6 @ 1/400 second to obtain this exposure. TTL meter readings often will give the correct exposure if made with the tilt and shift set to zero, but some bodies, such as the EOS 5/A2/A2E, require exposure compensation when used with an EF extender. When exposure compensation is required, it's usually stated in the camera manual or an addendum. The necessary compensation varies slightly among different lenses; unfortunately, the TS-E 45 mm f/2.8 isn’t listed in the compensation charts, so the compensation must be determined by testing. The procedure is simple, however:
Extension tubesThe TS-E 45 mm f/2.8 lens is compatible with the EF 12 mm extension tube. The lens is physically compatible with the EF 25 mm extension tube, but Canon do not endorse its use because of the loss of image quality. Incompatibilities
PrecautionsLens HandlingCaution: Sharp edges may be exposed when the lens is shifted or tilted; be careful when handling a lens that has been shifted or tilted. Return the shift and tilt to zero before removing the lens from the camera. Use with FiltersThe front element of the lens is very close to the front of the filter threads. Some filters may contact these front elements, damaging the lens, the filter, or both. Be especially careful when mounting non-Canon filters. Use with a Camera with a Built-In FlashWhen using a camera with a built-in flash, the top of a TS-E lens may contact the camera if the lens is rotated or removed from the camera with the lens shifted up. Ensure that the shift is set to zero before rotating the lens or removing it from the camera. Use with a TripodWith many tripod heads, a spacer such as the optional Canon tripod adapter may be needed to provide sufficient clearance to allow shifting or tilting. Clearance usually won’t be a problem on ball heads using an Arca-Swiss–style quick release, but the locking knob may need to be oriented toward the rear of the camera. The EOS-1D, or EOS-1/1n/1v or EOS-3 with a power-drive booster, and several other models with optional vertical grips, usually provide sufficient clearance without an additional spacer.
