High-grade HD coating for exceptional image rendition
The HD PENTAX-DA Limited interchangeable lenses are designed for use with K-mount lens-interchangeable digital cameras. These 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.
New HD coating
This lens uses a new-generation multicoating that reduces the reflection rate in the visible spectrum up to 50% more than conventional multicoating. This enables the reduction of flare and ghosting for the shooting of clear, high-contrast images even under backlighting and other adverse conditions.
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.
Premium quality of the Limited Lens-series
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.
