Pentax HD DA 21mm F3.2 AL Limited Lens in Black
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.
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.
