Full frame sized imageLenses that create APS-C sized image are designed for digital only. They cannot be used on cameras that have image sensor larger than the APS-C format. These lenses are not suitable for film cameras either. Ultrasonic AFLenses with ultrasonic focusing mechanism tend to be quiter and faster than traditionally focusing lenses. No stepping motor AFLenses with stepping motor focusing mechanism are better for contrast based focusing, and are quiter and faster than traditionally focusing lenses. One or more Low Dispersion lens element is usedLow Dispersion lens elements help to reduce chromatic aberration. Not stabilizedImage stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule. Metal mountCheaper lenses are usually equipped with plastic mount, while more expensive, professional lenses have metal mount. In general, metal mounts are more durable, and a good thing to have when lenses are changed a lot. When a camera is used mainly with one lens, the material of the lens mount is not that important. Internal FocusingInternally focusing lenses don't change their size while setting focus. Internal ZoomInternally zooming lenses don't change their size while focal length is changing. The front lens is fixedThe fixed front lens is not rotating during zoom and/or focusing. This allows the photographer to use petal shaped lens hood. Fixed front lenses also make the use of polarization filters a lot easier. Supports drop-in filtersDrop-in filters are used in those lenses where either the front lens is too large, or the field of view doesn't permit the use of traditional filters at the front of the lens. Usually bright tele and ultra-wide angle lenses support this filter type. |

Specially designed for digital as well as 35 mm SLR cameras, by continuously varying the angle of view from 8.2 degrees to 3.1 degrees, the lens takes a lot of the footwork out of picture composition. The HSM maked for fast AF speeds and quiet shooting a reality, and it is also capable of full-time manual focus. And, by adding an optional APO 1.4X Tele Converter, you can use this lens as a 420-1120 mm F8 MF ultra-telephoto zoom lens, or with a 2X Tele Converter, as a 600-1600 mm F11 MF ultra-telephoto zoom lens.
