HD PENTAX-D FA 70-210mm F4ED SDM WR: Weather-Resistant Telephoto Zoom Lens for DSLR Cameras

1. Discover the ultimate telephoto zoom lens designed for every adventure. Weighing approximately 819 grams, this compact and lightweight lens is perfectly tailored for handheld photography in the great outdoors. It covers a full-frame DSLR's 35mm image circle and boasts an impressive focal length range of 70mm to 210mm. When paired with an APS-C camera, the effective focal length expands to an equivalent of 107mm to 322mm in the 35mm format. The advanced optical design features 20 elements arranged in 14 groups, incorporating three Extra-low Dispersion (ED) glass elements along with two anomalous dispersion glass elements. This meticulous construction ensures high-resolution images with excellent contrast and edge-to-edge sharpness while effectively reducing distortion, chromatic aberrations, and coma aberrations. Its minimum focusing distance of 0.95 meters allows for diverse shooting opportunities, and the lens barrel maintains its dimensions during operation, enabling photographers to engage in various outdoor scenarios, from landscape shots and intimate close-ups of flora and fauna to sports and wildlife photography.

2. Experience enhanced imaging capabilities with the latest HD Coating technology from PENTAX. This superior multi-layer coating not only boosts light transmission but also mitigates average reflectance in the visible spectrum by over 50 percent. As a result, it significantly minimizes flare and ghosting effects, even in challenging backlit conditions.

3. Designed with outdoor photographers in mind, this zoom lens features a weather-resistant construction that safeguards against water intrusion. When used with a PENTAX weather-resistant digital SLR camera body, it guarantees a robust and reliable imaging system that excels in adverse conditions, including rain, mist, or environments prone to water splashes.

4. Additionally, this lens features Super Protect (SP) Coating on its front surface. Utilizing PENTAX’s unique fluorine deposition process, this advanced coating repels water, grease, and dirt, allowing for effortless cleaning of stubborn stains like fingerprints. Photographers can now focus on their craft without the constant worry of lens maintenance.

5. Including a built-in ring-type Supersonic Direct-drive Motor (SDM), this lens ensures quiet and swift autofocus performance, enhancing usability during outdoor photography sessions.

6. The lens is equipped with several other features aimed at maximizing user experience. Its Quick-shift Focus System allows for an immediate transition to manual focus after locking onto a subject with autofocus by partially depressing the shutter release button. Moreover, the two-step focus range limiter minimizes autofocus operation time for efficiency. The nine-blade, round-shaped diaphragm produces a beautifully natural bokeh effect, reducing streaking from point light sources. Additionally, the electromagnetic diaphragm control provides precise exposure control during video recordings, which is available when mounted on specific PENTAX camera bodies like the K-1 Mark II, K-1, K-3 II, K-3, KP, K-70, K-50, K-S2, or K-S1.
