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. Internal FocusingInternally focusing lenses don't change their size while setting focus. No drop-in filter supportDrop-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. |

Ideal for digital as well as 35 mm SLR cameras, this is a telephoto macro lens that is capable of life-size shots. Its floating inner focus system allows high performance. SLD (Special Low Dispersion) glass is used for superior correction of all types of aberrations. The HSM models provide full-time manual focus. With the addition of an APO 1.4X Telen Converter, the lens can be used as a 252 mm AF lens that automatically switches to MF when the subject is less than 1.2 m away (models with a Minolta mount or Pentax mount are only capable of MF). And with a 2X Tele Converter, it can be used as a 360 mm MF lens.
