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.

Super wide lens using HD coating and a round iris diaphragm for delineation performanceThis super wide lens uses an aspherical lens and extra-low dispersion (ED) glass lens to correct distortion and chromatic aberration for delineation performance. The curvature of the first lens front surface was reduced, and it supports use of a circular polarizing filter. The lens also includes a built-in retractable sliding flower-shaped hood.

• 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 iris diaphragm is used to enable rendering of soft round out-of-focus (bokeh) effect for illumination, shimmering on water surfaces, and other point light sources.
• Super wide lens with focal length equivalent to 23mm in 35mm film format for shooting emphasizing perspective and larger depths of field and for capturing wide photos with other unique imaging effects.
• Based on the design concept of the Limited series, this lens provides sharp, high contrast, clear imaging performance that is optimized for digital images.
• This super wide lens includes top-level correction for distortion and corrects magnification chromatic aberration and other aberration types for delivering delineation performance.
• New optical system for a exceptionally compact and lightweight design.
• Lens barrel, hood, and cap use a machined aluminum material.
• Instead of a dome-shaped protrusion, the lens front has a flat shape for enabling attachment of frequently-used circular polarizing light filters and commercially-available 49mm size filters for landscape photos.
• Retractable sliding flower-shaped hood that can be stored out of the way.
• Minimum shooting distance of 0.18m is possible.
• Quick-Shift Focus System for enabling manual focus operation after focusing by AF without any switching operation.
• SP (super protect) coating for protecting the lens front surface from water and dirt
