TOKINA 10-17mm F3.5-5.4 for Canon

The Tokina 10-17 F3.5-5.4 is a fisheye zoom lens for the digital SLR sensor APS-C format. The 10-element lens with a focal length of 10-17mm has water repellent coating, which also makes cleaning fingerprints and drops of water from the surface of the lens easier. It has 8 groups, including one SD glass element (Super-Low Dispersion]. It increases the image display quality and reduces the number of elements in the group. As a result, your lens is much more compact with faster focusing. The minimum focus distance is 14cm and the macro ratio is 1:2.56. This lens is designed specifically for Canon's digital SLRs.
