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. No 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. Not SealedWeather sealed lenses are protected from dust and water. While they are not water proof, these lenses can be used in rain and other humid environments. Some sealings only provide protection against dust or water, not both. Sealing is only available when the lens is used on a similarly weather sealed camera body. 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. |

A high performance standard zoom lens can capture a wide range of subjects. An aspherical lens satisfactorily compensates for distortion aberration throughout the zoom range. Compact and lightweight, this lens has excellent imaging capability and is easy to use. From 28mm wide to 105mm tele range this zoom lens has 50cm minimum focusing distance. It has also maximum magnification of 1:5.6. An aspherical lens satisfactorily compensates for distortion aberration and produces a top quality optical performance throughout the entire zoom range. This advanced design has also resulted in a compact and lightweight lens. This lens also incorporates a double-cam inner focusing zoom system that ensures compact and lightweight lens with excellent imaging capability and easy to use. As The front of the lens does not rotate, circular polarizing filters and a petal-type hood can easily be used.
