RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of the HD PENTAX-DA 55-300mmF4-5.8ED WR interchangeable lens, designed for use with K-mount lens-interchangeable digital SLR cameras.

In addition to its approximately 5.5 times zoom ratio covering focal lengths from medium telephoto to super telephoto, the new lens features PENTAX-original HD coating* to deliver sharp, clear images even under such demanding lighting conditions as backlight. Its weather-resistant construction also enhances reliability and durability during challenging outdoor shooting conditions, allowing the photographer to capture high-impact telephoto images without worries.

Main Features

1. Approximately 5.5-times zoom ration in telephoto range

With its wide zoom coverage of approximately 5.5 times, the lens offers focal-length coverage from 84.5 medium telephoto to 460mm super telephoto (in the 35mm format), making it ideal for use with a wide variety of subjects and applications including portraits, sports and landscapes. It incorporates two ED (Extra-low Dispersion) glass elements in its optics to effectively compensate for chromatic aberrations over the entire zoom range and deliver well-defined, true-to-life images.

2. High-grade HD coating* for exceptional image rendition

The lens is treated with HD coating,* a PENTAX-exclusive multi-layer lens coating that assures higher light transmittance and lower reflectance than conventional multi-layer coatings. This means it produces sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight.

* HD stands for High Definition.

3. Dependable weather-resistant construction

The lens features weather-resistant construction to prevent the intrusion of water and moisture into the lens barrel. When the lens is mounted on a PENTAX weather-resistant digital SLR camera body, the user is assured of greater durability and reliability when shooting in rain or mist, as well as at locations subject to a spray or splash.

4. Quick-Shift Focus System

The lens features the Quick-Shift Focus System, which allows the user to instantly switch to manual-focus operation after the subject is captured in focus by the camera's AF system.

5. Other features

  • ・SP (Super Protect) coating to keep the front surface free of dust and stains.
  • ・Highly dependable metallic lens mount.
