Pentax HD DFA 70-210mm f4 SDM WR

HD PENTAX-D FA 70-210 mm F4 ED SDM WR

The HD PENTAX-D FA 70-210 mm F4 ED SDM WR is a compact and lightweight telephoto zoom lens that is the perfect companion for any photography trip. With its small dimensions and a weight of just 819 grams, RICOH IMAGING is responding to feedback from many PENTAX photographers who wanted a more manageable "light version" of the successful PENTAX-D FA 70-200mm F2.8 ED DC AW. As a result, the new lens with its wide focal length range is suitable for a variety of applications, including travel, sports, reportage, wildlife and landscape photography.

The lens construction, with a total of 20 elements in 14 groups, includes three ED (Extra-low Dispersion) glass elements and two anomalous dispersion glass elements. This compensates for distortion, coma and chromatic aberration and creates the conditions for high-contrast images with high resolution and sharpness right to the edge of the image. Thanks to the internal focusing, the overall length of the lens barrel remains constant, which significantly simplifies handling in many shooting situations. The minimum focusing distance of just 0.95 meters, with a magnification factor of 0.32, also opens up many possibilities for interesting close-ups, e.g. of animals and plants, with a beautiful bokeh effect (defocusing) in the foreground and background.

Fast focus thanks to SDM motor

The new HD PENTAX-D FA 70-210 mm F4 ED SDM WR telephoto zoom lens is equipped with the latest generation Supersonic Direct Drive (SDM). When used with cameras designed for it, such as the PENTAX K-1 Mark II, it enables fast and nearly silent focusing to capture every exciting moment.
In addition, the lens is equipped with a two-stage focus range limiter that can be used to restrict the focus range and thus shorten the focusing time.

Input aperture of F4 for perfect image composition

The circular aperture of 9 blades creates an image in which point light sources appear to be enveloped by soft, circular light. Even with normal subjects, this creates a natural bokeh effect in the background and highlights are rendered as beautifully blurred as well as perfectly round points of light, which is an impressive composition tool not only for portraits.
The constant aperture of F4 as the input light speed not only simplifies exposure control, but also offers many possibilities in image composition.

Weatherproof construction

Designed as a WR (Weather Resistant) model, this telephoto zoom lens features a weather-resistant construction with seven special sealing rings that effectively prevents dust and moisture from entering. Together with a weather-resistant PENTAX digital SLR camera, the lens forms a reliable shooting system that delivers outstanding performance even in difficult outdoor conditions such as rain or fog.

Lens refinement for high brilliance

The HD PENTAX-D FA 70-210 mm F4 ED SDM WR is equipped with the latest HD (High Definition) coating. Compared to conventional multi-layer coatings, this coating, developed exclusively by PENTAX, not only improves light transmission but also reduces the average reflectance in the visible light range by more than 50 percent. This minimizes the adverse effects of flare and ghosting - even in challenging backlit lighting conditions.

Protection against dirt

The SP lens coating (Super Protect), also developed by PENTAX, with a special fluorine coating on the front lens is extremely water-, grease- and dirt-repellent, so that outdoor photographers in particular can concentrate on their subjects in nature without any worries. And if stains do appear, for example due to fingerprints, they can be easily removed.

Manual focusing despite autofocus

With the user-friendly Quick Shift Focus system, it is possible to switch effortlessly from autofocus to manual focus without having to switch. For extra-fine focus adjustment or to correct autofocus, simply rotate the focus ring during AF operation and it instantly switches to manual focus mode.

Fast and quiet aperture control

The HD PENTAX-D FA 70-210 mm F4 ED SDM WR is equipped with a KAF4 bayonet that features electromagnetic aperture control. Unlike mechanical control, where aperture control is provided by the camera body, the drive motor is integrated as a unit in the lens barrel. This ensures extremely precise iris control with low operating noise, smooth running and minimal vibration, which is not only a positive feature when shooting video.
