Major Features (common to all five models):
1. High-grade HD coating for exceptional image rendition
HD PENTAX DA Limited 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, HD PENTAX DA Limited lenses produce sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight.
*HD stands for High Definition, and signifies the lens’s capacity to reproduce images that excel in transparency, definition, resolution and rendition.
2. 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.
3. Acclaimed Limited Lens-series qualities 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 supreme 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.
4. Enhanced exterior design signifying HD series
While inheriting traditional design features of DA PENTAX Limited Lenses the new HD PENTAX DA Limited lens series features a red anodized ring on the front of the focus ring to signify the presence of new HD PENTAX lens coating and enhance its exclusive appearance.
5. Other features
- SP (Super Protect) coating (already featured in four other lenses) has been applied to the HD PENTAX-DA 40mm F2.8 Limited to keep the front surface free of dust and stains.
- All the lenses come in a silver version in addition to the black version.
