Ricoh has announced the launch of a new HD Pentax-DA 55-300mm f/4-5.8ED WR telephoto lens.
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.
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.
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 reflection than conventional multi-layer coatings. This means it produces sharp, clear images free of flare and ghost images, even in adverse lighting conditions.
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, such as the new K-3, 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.
Quick-Shift Focus System
The lens features the Pentax-developed 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.
- SP (Super Protect) coating to keep the front surface free of dust and stains.
- Highly dependable metallic lens mount.
