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. No 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. 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. |

The SMC PENTAX-FA Macro 200mm f/4 ED [IF] telephoto macro lens offers a minimum focusing distance of 1.69 feet for the maximum magnification of life-size. Its working distance of 11 inches at life size is the longest in its class, allowing for the high-magnification photography of subjects which are not always easily approachable by the photographer. It incorporates two Extra-low Dispersion (ED) lens elements and features an Inner Focus (IF) mechanism to improve brightness at the edges of the image field even when shooting at close range.
