Parsippany, NJ—Ricoh Imaging Americas Corporation unveiled the HD Pentax-D FA 21mm F2.4ED Limited DC WR lens. The new lens works with Pentax K-mount, full-frame digital SLR cameras. When used with Pentax APS-C-format cameras, it provides a focal length equivalent to 32mm in the 35mm format.

The ultrawide-angle, fixed-focal-length lens is the newest model in the Pentax Limited series, acclaimed for distinctive image rendition and exterior design.

Moreover, the new lens is the first D FA-series lens in the Pentax Limited lineup to optimize the visual characteristics of digital images. “The lens captures the prevailing ambience and true-to-life sense of depth of the scene and is designed to make photography enjoyable for its users—essential elements of the Pentax Limited series,” the company announced.

The 21mm ultrawide-angle focal length, not previously available in the FA Limited series, is ideal for landscape photography. At open aperture, the lens achieves a mild bokeh (defocused) effect in the background while capturing the main subject in sharp, crisp focus. This enables the subject to stand out against a defocused background, with the exaggerated perspective typical of ultrawide-angle lenses.

Furthermore, at a minimum focusing distance of seven inches, the lens can create a variety of visual expressions, depending on the subject being captured.

Optical Specs

The lens optics incorporate five glass elements; they comprise four ED (extra-low dispersion) glass elements—including one ED aspherical lens—and one super ED glass optical element. These elements minimize chromatic aberration and prevent color bleeding, in both the main in-focus area and surrounding defocused areas.

It also employs 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. This design reduces the lens’s overall size while delivering crisp images.

What’s more, Pentax-original High-Definition (HD) coating reduces the average reflectance in the visible spectrum to less than 50%. Thus, it effectively minimizes flare and ghost images even in backlighting.

In addition, the lens integrates a DC motor inside its barrel—a first for the Limited D FA series. The motor helps assure smooth, quiet, precision, high-speed autofocus. This focusing mechanism also provides a quieter drive sound and smoother operation than traditional body autofocus.

The lens barrel, hood and cap are machined from high-grade aluminum, and the lens also features weather-resistant construction. Additionally, Ricoh applied an SP (super protect) coating to the front surface to repel dust and stains. Consequently, when paired with a Pentax weather-resistant DSLR camera body, the lens is part of an airtight digital imaging system. HD-PENTAX-D-FA-21mm-F2.4ED-Limited-DC-WR-cap

Finally, the lens incorporates the KAF4 mount with an electromagnetic diaphragm mechanism for precision exposure control when used with compatible DSLRs. It also helps assure worry-free video shooting in locations prone to dramatic brightness changes; such as a stage with rapidly changing lighting conditions.

The HD Pentax-D FA 21mm f/2.4ED Limited DC WR lens has a suggested retail price of $1,399.95. The black lens models are marked with a serial number starting with 0000001; the silver models start with 1000001.
