Ricoh adds 15-30mm F2.8 SDM WR and 28-105mm F3.5-5.6 ED DC WR to full-frame lens range
Ricoh has expanded its full-frame lens range, announcing the HD Pentax-D FA 15-30mm F2.8 and FA 28-105mm F3.5-5.6 alongside the introduction of the full-frame K-1 DSLR. The 15-30mm F2.8 brings a fast, constant wide-angle zoom to the lineup offering a Supersonic Direct-drive Motor, rounded nine-blade aperture, and close focus distance of 28cm. The 28-105mm offers a DC motor and a minimum focus distance of 0.5m.
The 'WR' in their names means that these lenses are weather-resistant, with SP (Super Protect) coatings on the front lens element to repel water.
The 15-30mm F2.8 and 28-105mm F3.5-5.6 join two Pentax full-frame lenses announced last year, the HD Pentax D FA* 70-200mm F2.8 and FA 150-450mm F4.5-5.6.
Ricoh announces HD PENTAX-D FA 15-30mm f/2.8 lens for new PENTAX K-1 full-frame DSLR
Weather-sealed, ultra-wide-angle zoom lens, ideal for landscapes and nightscapes
DENVER, Colo. February 17, 2016 – Ricoh Imaging Americas Corporation today announced the HD PENTAX-D FA 15-30mm f/2.8ED SDM WR lens. This new lens is designed to work seamlessly with the full-frame sensor of the new PENTAX K-1 camera, also announced today.
When mounted on the PENTAX K-1 camera body, the lens covers a focal-length range from 15mm ultra-wide-angle to 30mm wide-angle.(Note: with a PENTAX APS-C-size digital SLR camera body, the lens covers a focal-length range from 23mm to 46mm.) Its exaggerated ultra-wide perspective and state-of-the-art optical design enable capturing high-resolution, dynamic, sweeping views of subjects, ideal for landscape photography. Treated with PENTAX-developed HD Coating, the lens produces well-defined, fine-detailed images with ample light levels even at the edges of the image field, while effectively reducing chromatic aberration and distortion to a minimum.
Its large f/2.8 maximum aperture is also well-suited for photographing nightscapes and starry skies. The built-in SDM (Supersonic Direct-drive Motor) provides quiet, high-speed autofocus operation.
| Pricing and Availability |
HD PENTAX-D FA 15-30mm f/2.8ED SDM WR lens will be available in April 2016 at www.ricohimaging.com and retail outlets nationwide for a manufacturer’s suggested retail price of $1,499.99.
1. Exceptional imaging power
When mounted on the PENTAX K-1 35mm full-frame digital SLR camera body, the lens provides an ultra-wide-angle focal-length coverage from 15mm to 30mm. Its exaggerated perspective helps the photographer produce spectacular landscape photographs. With a 30mm focal length at the telephoto end, the lens is also well-suited to portrait and street photography.
2. State-of-the-art optical design
The zoom lens incorporates three ED (Extra-low Dispersion) glass optical elements and three aspherical optical elements in its 18-element, 13-group optics to deliver high-resolution images rich in contrast even at the edges of the image field, while effectively minimizing chromatic aberration, distortion and coma.
3. Large-aperture zoom lens, with a maximum aperture of f/2.8
Since this zoom lens provides a maximum aperture of f/2.8 over its entire zoom range, it is versatile enough to be used for many different subjects and scenes, ranging from sweeping landscapes to nightscapes and starry skies. Despite its ultra-wide-angle perspective, it can capture the subject with an excellent bokeh (defocus) effect on the background. Even in macro photography from its minimum focusing distance of 28 centimeters, it can capture subjects with a well-defined sense of depth.
4. Built-in SDM (Supersonic Direct-drive Motor)
The incorporation of a new-generation SDM (Supersonic Direct-drive Motor) assures that this zoom lens provides quiet, high-speed autofocus operation, letting the photographer react swiftly to all types of subjects.
5. Weather-resistant construction
Special seals applied throughout the lens body provide this zoom lens with dependable weather-resistant construction, effectively preventing the intrusion of water into the lens interior. By pairing it with a weather-resistant PENTAX digital SLR camera body, the photographer has a durable, dependable digital imaging system that performs superbly under demanding shooting conditions — even in the rain or mist, or at locations prone to water splashes or spray.
6. HD Coating to improve image description
The lens is treated with high-grade, multi-layer HD (high-definition) coating. Compared with conventional multi-layer coatings, this PENTAX-original coating assures higher light transmittance and less reflection to deliver bright, high-contrast images free of flare and ghost images, even under demanding lighting conditions such as backlight.
7. Other features
- Quick-Shift Focus System for instant switching from autofocus to manual-focus operation, by holding the shutter-release button halfway down and turning the focus ring after the subject is captured in focus by the camera’s AF system.
- Rounded diaphragm with nine blades produces a smooth, beautiful bokeh (defocus) effect, while minimizing the streaking effect of point light sources.
- SP (Super Protect) coating applied to the front surface of the lens to effectively repel water and grease.
