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. Internal FocusingInternally focusing lenses don't change their size while setting focus. |

The smc P-FA Zoom 28mm~105mm f/3.2~f/4.5 AL [IF] standard zoom lens is the perfect standard zoom lens for both beginning and advanced photographers. Compact and lightweight, it provides wide-to-telephoto zoom coverage and high-quality image reproduction. The incorporation of a hybrid aspherical lens element contributes to the improvement in image quality and the reduction of coma and spherical aberrations. An internal focusing system ensures faster and smoother focusing.
