More True-to-Life Image Reproduction Than Most Comparable Lenses

Pentax 12-24mm f/4 Lens The Pentax SMCP-DA 12-24mm f/4 ED AL lens was developed for exclusive use with Pentax digital SLR cameras, and is a compact, lightweight two-times zoom lens that offers an ultra-wide-angle perspective equivalent to 18.5mm to 37mm in the 35mm format.

The image circle in DA-series lenses is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in Pentax digital SLR cameras to optimize camera performance. This design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications.

Boasting extra-low-dispersion (ED) glass elements and two aspherical lens elements, the Pentax DA 12-24mm f/4 wide-angle lens offers more true-to-life image reproduction than most comparable lenses. The lens--which is compatible with Pentax and Samsung digital SLR cameras--offers an image circle that's designed to perfectly match the 23.5 x 15.7mm size of the Pentax digital CCD. This helps optimize camera performance so that you can capture terrific shots of landscapes, family portraits, or sporting tableaus. The responsive Quick-Shift Focus system, meanwhile, makes it easy to instantly shift from autofocus to manual focus. And thanks to the aforementioned ED glass elements, the lens offers superior sharpness and color correction. Other features include a metal Pentax KAF lens mount, a lens hood that minimizes flare and ghost images, and a 1-foot close focusing distance.

Note! Not suitable for 35mm film SLR cameras.
