RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of five HD PENTAX-DA Limited interchangeable lenses designed for use with K-mount lens-interchangeable digital cameras. These new lenses inherit the distinctive visual description and a premium appearance of the acclaimed PENTAX Limited Lens series, while adding the state-of-the-art HD coating and a round-shaped diaphragm, to deliver even higher digital imaging performance in combination with a K-mount camera body.
Developed based on the Limited Lens series -- renowned for the meticulous finish in every detail from the outstanding image rendition to the high-quality, hand-machined aluminum body -- these new lenses assure even better optical performance than the original Limited Lens-series models. They are treated with the HD coating, which assures much higher light transmittance than conventional multi-layer coatings to deliver sharp, clear images free of flare and ghost images, even under such demanding conditions as backlight. They also feature a completely round-shaped diaphragm to produce a natural, beautiful bokeh (out-of-focus) effect in the foreground and background.
Major Features (common to all five models)
High-grade HD coating for exceptional image rendition
All lenses are treated with HD coating,* a high-grade multi-layer lens coating that assures higher light transmittance and lower reflectance than conventional multi-layer coatings. As the result, they produce sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight.
* HD stands for High Definition.
Round-shaped diaphragm for beautiful out-of-focus rendition
All lenses feature a completely round-shaped diaphragm to optimize the performance of their distinctive optics. This diaphragm produces a natural, beautiful bokeh (out-of-focus) effect, while minimizing the streaking effect of point light sources.
Acclaimed Limited Lens-series quality for distinctive visual description and a premium appearance
While inheriting the design concept of the Limited Lens series, these lenses were designed by combining a series of mechanical and numerical evaluations with human assessment of test-shooting samples to assure the ultimate in image reproduction. Their optical design has been optimized for digital photography to deliver sharp, clear images with outstanding contrast, even at the maximum aperture. In addition, their lens barrel, hood and cap are all made of a high-grade aluminum material, hand-machined for perfect proportions and beautiful texture.
Other Features
- ・SP (Super Protect) coating (already featured in four other models) has been applied to the HD PENTAX-DA 40mm F2.8 Limited lens to keep the front surface free of dust and stains.
- ・All the lenses come in a silver version in addition to the black version.
