For discerning architectural photographers, there is great need for wide angle lenses. 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 wide Canon 24mm f/3.5L TS-E Lens. 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 (16 elements/11 groups) for low distortion and high resolution to the edge of the image. Tilt and shift mechanism rotates Â±90Â° allowing shift in any direction Tilt mechanism rotates Â±90Â° allowing tilt in any direction relative to the shift. One Aspherical and three UD lens elements minimize chromatic aberration Sub-wavelength structure and super-spectra coatings minimize ghosting and flare. Circular aperture for creative, blurred highlights.
