Description:

The HD Pentax-D FA 21mm F2.4 Limited is the first full-frame Limited lens featuring a built-in silent autofocus motor and weather sealing. It is a premium ultra-wide lens with metal finish in the style of the FA Limited lenses and with an emphasis on top-notch optical performance. The aperture mechanism is controlled electronically (KAF4 mount)*.

At 21mm this lens is a nice supplement to the FA limited lenses and to a walk-around zoom like the D FA 28-105mm  zoom.

Its optics incorporates four ED (Extra-low Dispersion) and one Super ED (Extra-low Dispersion) glass optical elements. RICOH states that this will minimize chromatic aberration and prevent color bleeding, not only in the main in-focus area, but also in the surrounding defocused areas. It also features a large-aperture negative meniscus optical element, a biconvex aspherical glass-mold optical element, and a high-refraction glass optical element in the first lens group, to reduce overall size despite its ultra-wide-angle design. RICOH claims that this lens will deliver outstanding imaging performance for sharp, crisp images without any fuzziness, even in peripheral areas. Stay tuned for our upcoming test of the D FA 21mm lens which will look into these claims.

*  Cameras compatible with this system are the K-50 and newer. For K-1, K-3 II, K-3, K-S2, K-S1 and K-50, the camera’s firmware must be upgraded to the latest version. If this lens is mounted on a camera without proper firmware upgrade, its diaphragm control mechanism becomes inactive leaving the aperture fixed at F2.4, making it difficult to obtain correct exposure.
