The widest tilt-shift lens in Canon’s lineup, the new TS-E 17mm f/4L lens expands shooting possibilities exponentially on EOS Digital cameras. Designed with UD glass to minimize and compensate for chromatic aberrations, with a specially coated aspherical element for the highest possible glare-free image quality, this tilt-shift lens offers a diagonal angle of view of 104° on a full-frame SLR camera.New TS rotation lets users freely combine tilting and shifting within the range of +/- 90° in the direction of movement. The lens also has an improved tilt & shift knob with an enhanced range of movement of up to +/- 6.5° and 12mm repectively, with a revolving function for better operability. It uses a circular aperture for beautiful out-of-focus areas and has an SWC lens coating to control ghosting and flare to a far greater degree than with earlier coating technologies.

For discerning architectural photographers, there is no lens that is too wide. Tilt and shift movements, features normally found on large format cameras, can be bestowed upon a smaller format of camera with a lens such as this Canon 17mm f/4L TS-E Lens.

Being a Canon “L” lens, by definition it is a premium Canon optic. The 17mm TS-E has several distinct elements that make it stand apart from more common glass. Firstly, designers integrated a set of physical controls that allows users to rotate the direction of the tilt and shift independently of one another. Secondly, there is ±6.5° of tilt and ±12mm of shift that gives photographers ample ability to correct for perspective when taking images of interior or exterior spaces, and landscapes.

• EF mount lens is compatible with all Canon EOS cameras
• Wide image circle of 67.2mm is 50% greater than 35mm/full frame film area
• High precision glass (18 elements/12 groups) for low distortion and high resolution to the edge of the image
• Tilt and shift mechanism rotates ±90° allowing shift in any direction
• Tilt mechanism rotates ±90° allowing tilt in any direction relative to the shift
• One Aspherical and four UD lens elements minimize chromatic aberration
• Floating internal focus mechanism delivers high image quality throughout focus range
• Sub-wavelength structure and super-spectra coatings minimize ghosting and flare
• It uses a circular aperture for beautiful out-of-focus areas and has an SWC lens coating to control ghosting and flare to a far greater degree than with earlier coating technologies.
