Ricoh has announced two new zoom lenses for Pentax K-mount DSLRs, the HD Pentax-D FA * 70-200mm F2.8ED DC AW and HD Pentax-D FA 150-450mm F4.5-5.6ED DC AW. Both are designed to cover a full-frame sensor and are built to withstand exposure to dust and moisture. The 70-200mm is the first full-frame telephoto zoom to bear Pentax's 'Star' designation, and the 150-450mm will offer the longest reach for a telephoto zoom in Pentax's lens lineup.

On their own, the introduction of these lenses would certainly point to plans for a full-frame K-mount camera in the works, and Ricoh has confirmed that in a simultaneous announcement today. Both lenses will be available in March, with the HD Pentax-D FA * 70-200mm F2.8ED DC AW selling for $2299.95 and the HD Pentax-D FA 150-450mm F4.5-5.6ED DC AW at $2499.95. 

Press release:

Ricoh Imaging Broadens Lens Line-up-Providing Photographers with Two New Options to Capture Outstanding Sports, Action and Landscape Photography.

With the Introduction of the HD PENTAX D FA * 70-200mm F2.8 and the HD PENTAX D FA 150-450mm F4.5-5.6, photographers have exceptional lens options to use with current and future imaging sensor technology. 

DENVER, Colorado, February 4, 2015- RICOH IMAGING AMERICAS CORPORATION is pleased to announce the launch of two new HD PENTAX D FA Lenses. Designed for use with current PENTAX K-mount DSLR cameras and future PENTAX sensor technology, these lenses offer ranges not found in previous PENTAX lens models, including a star-series telephoto zoom and super-telephoto zoom ideal for capturing clear images of distant subjects and weather resistant for shooting in all conditions.

The HD PENTAX D FA lenses feature a high-grade HD Coating which helps to produce extra-sharp, high-contrast images, minimizing flare and ghosting, even under demanding lighting conditions such as in backlight situations. 

The HD PENTAX-D FA * 70-200mm F2.8ED DC AW has a brand new optical design in the PENTAX Star (*) series, which boasts the highest image quality of all PENTAX interchangeable lenses. In addition to the HD coating, this lens features Aero Bright Coating II, assuring exceptionally low reflectance. Thanks to its large- constant aperture design, the lens provides an accelerated maximum aperture of F2.8 at all focal lengths from 70mm to 200mm. In addition to four super-low dispersion glass elements and two ED (Extra-low Dispersion) glass elements, its optics includes a pair of new Super ED glass elements to effectively compensate chromatic aberration over the entire zoom range and deliver crisp, high-resolution images with edge-to-edge sharpness. Its dustproof, weather-resistant body also makes it extremely dependable and durable in demanding outdoor conditions. This new lens boasts fast yet quiet internal focusing, zoom versatility, and an AF limiter switch which improves autofocus response time.

The HD PENTAX-D FA 150-450mm F4.5-5.6ED DC AW covers focal lengths from 150mm to 450mm — a focal-length range demanded by higher end PENTAX-camera users. Also incorporated are three ED (Extra-low Dispersion) glass elements and a super-low dispersion glass element to effectively compensate chromatic aberration. The highly desirable weather-resistance body protects the inside of the body from both dust and moisture, making it an extremely dependable and durable DSLR accessory in demanding outdoor conditions.

“Ricoh Imaging continues to provide quality and performance in lens construction,” said Jim Malcolm, President, Ricoh Imaging Americas Corporation. “With the addition of two new zoom lenses, we demonstrate our commitment to helping photographers reach their full potential.”
