Sigmas EX DG filters benefit from multi-layer lens coating, developed to counteract the highly reflective characteristic of image sensors. With older style filters, light would reflect off the image sensor, bounce off the lens & filter elements & re-enter the image sensor, creating a ghost image. In addition to this, an optimum, neutral color balance is ensured, increasing the white balance accuracy of the digital camera. ...

This autofocus fisheye lens is designed for use with digital SLR cameras equipped with APS-C size image sensors. The Nikon version produces a diagonal angle of view of 180° (154° for Sigma, 167° for Canon). The diagonal field of view of this fisheye lens produces striking images with exaggerated perspective & distortion. The minimum focusing distance of 13.5cm/5.3inch, & maximum magnification 1:3.3 allows subjects to be as close as 1.8cm/0.7inch from the lens' front element. This close focusing capability allows close-up photography & also it is possible to make use of large depth of field that covers wide range of subjects. ...
