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.
This lens uses Extra-low Dispersion (ED) glass for correcting chromatic aberration. Aspherical lenses (AL) are also used for providing superior correction of spherical aberration.
The PENTAX DA 12-24mm f/4 ED AL [IF] is a compact, lightweight lens lets the photographer capture unique, eye-catching images with its ultra-wide-angle perspectives and is the ideal choice for wide-angle photographers who want the maximum angle of view possible in a non-fisheye lens. It features the PENTAX-original SP (Super Protect) coating which repels dust, water and grease to keep the lens clean and image quality at its peak. Extra-low Dispersion (ED) glass offers superior sharpness with minimal chromatic aberration. The PENTAX-original Quick-Shift Focus System allows instant switching from autofocus to manual focus operation.
