Ricoh Imaging Canada Inc. has announced the introduction of the HD Pentax-DA 20-40 mm f/2.8-4 ED Limited DC WR interchangeable lens, designed for use with Pentax K-mount interchangeable lens digital cameras. As the first zoom lens in Ricoh Imaging’s acclaimed Limited Lens series, the new HD Pentax-DA 20-40 mm f/2.8-4 ED Limited DC WR lens features the Pentax high-grade multi-layer High Definition (HD) coating and is the first Limited Lens to feature Ricoh Imaging’s durable and dependable weather-sealed construction.
The HD Pentax-DA 20-40 mm f/2.8-4 ED Limited DC WR lens combines Ricoh Imaging’s optical technology and premium construction culminating in the production of rich images with exceptional visual description and meticulous finish in every detail. With its handy zoom range (30.5 mm to 61.5 mm in the 35-mm format), it is the ideal everyday lens, offering the most frequently used focal lengths required for many popular applications, such as scenic photography, snapshots and portraiture. It features a bright f/2.8 maximum aperture (at 20 mm) and rounded diaphragm blades producing stunning bokeh. At higher aperture numbers, its superior optical design incorporates ED (Extra-low Dispersion) glass elements and a proprietary HD coating that delivers clear crisp, high-contrast images free of flare and ghosting. It also features a lens-based direct current (DC) focusing motor providing quiet and smooth autofocus functionality.
The HD Pentax-DA 20-40 mm f/2.8-4 ED Limited DC WR lens, available in a choice of black or silver, will be available in Canada December 2013 at a suggested retail price of $999.99.
The first two-times zoom lens in the Limited Lens series
With its two-times zoom coverage from 20 mm to 40 mm, this lens offers a focal-length coverage from 30.5 mm to 61.5 mm (in the 35-mm format) when mounted on a Pentax K-mount interchangeable lens digital camera body. It delivers a convenient and useful focal length with standard to moderate wide-angle coverage, ideal for a wide variety of subjects and settings.
Acclaimed Limited Lens-series quality for superb visual detail and premium appearance
Inheriting the design concept of the Limited Lens series, this lens is designed with an optical construction that faithfully reproduces the feeling of depth while minimizing astigmatism over the entire zoom range. It allows the photographer to optimize the subject’s visual detail by making images softer at larger apertures and sharper at smaller apertures. Its lens barrel, hood and cap are made of a high-grade aluminum material, and hand-machined for perfect proportions and beautiful texture. Positioned in the mid-section of the lens barrel, the zoom ring features a series of knurled grooves to facilitate zooming operation.
State-of-the-art optical technology
The lens has been treated with the Pentax-developed HD coating*, a high-grade, multi-layer coating that reduces reflectance in the visible light spectrum to less than 50 percent of that of conventional multi-layer coatings, allowing the user to capture crisp, high-contrast images free of flare and ghost images, even under difficult lighting conditions such as backlight. It also incorporates an ED (Extra-low Dispersion) glass and a super-low-dispersion glass element in its optics to deliver clear, high-resolution images with edge-to-edge sharpness, while effectively compensating for chromatic aberrations over the entire zoom range.
* HD stands for High Resolution.
The first weather-resistant lens in the Limited Lens series
This lens is the first Limited Lens-series model to feature a weather-resistant construction, with seven special seals to prevent the intrusion of water and moisture into the lens interior. By mounting it on a Pentax weather-resistant digital SLR camera body, the user is assured of greater durability and reliability when shooting in the rain or mist, as well as at locations subject to spray or splashes.
• Smooth, quiet AF operation using a lens-installed AF driving motor.
• Rounded diaphragm produces a natural, beautiful bokeh (blur) effect, while minimizing the streaking effect of point light sources.
• 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.
• SP (Super Protect) coating to keep the front surface free of dust and stains.
• A choice of black or silver colour.
