The PENTAX smc P-DA J 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 color rendition, and aspherical lens elements to help transmit the light more efficiently through the lens to the film.

Canon EF 24mm F 1.4L focal length of 24mm and a USM focus motor providing full-time manual focus also make the Canon EF 24mm F 1.4L ideal for situations where a wide-angle, high-performance lens is required. Chromatic aberration common in wide-angle shooting is also reduced by the inclusion of two UD lenses, which ensure optimum image quality and corner-to-corner detail.
