APS-C 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. |

The SMC PENTAX-DA 16-45mm F4.0 ED/AL is recommended for use with digital cameras. It features a 3X zoom ratio with focal lengths covering ultra-wide angle to normal ranges, incorporates a high-refraction extra low dispersion (ED) glass element to produce a high-resolution, high-contrast image with true-to-life colour rendition, and aspherical lens elements to help transmit the light more efficiently through the lens to the film. The SMC PENTAX-DA J 16-45mm F4.0 ED/AL is well-suited for advanced amateurs and professionals
