Super Multi-layer coating reduces flare and ghosting, four aspherical lenses provide correction for distortion and inner focusing system eliminates front lens rotation and suitable for use of polarizing filters. Perfect for shooting landscape photography, architecture, building interiors, photojournalism, wedding photography, group pictures and more.

DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is made to match the smaller dimensions used for the image sensor on digital cameras. As a result, these lenses are also more compact and lightweight, and are better matched to digital SLR cameras.

Note!

(*) Not suitable for 35mm film SLR cameras or for any digital SLR camera with image sensor bigger than APS-C size, e.g. 1D series or Kodak Pro SLR/c.
