 | Top | Major Features | Specification |


PENTAX Corporation is pleased to announce the introduction of the smc PENTAX-DA 21mm F3.2AL Limited lens, designed for exclusive use with its digital SLR cameras. Thanks to its ultra-thin, pancake design, this wide-angle lens offers go-anywhere portability, as well as a versatile, all-purpose angle of view that makes it ideal for casual, day-to-day snapshot photography. The latest model of PENTAX's acclaimed Limited Lens series, this new lens inherits all the attributes of this renowned series, including high-quality image reproduction, distinctive visual description, and high-grade lens-barrel finish.


Major Features
  1. Ultra-thin, super-lightweight design

    Thanks to its newly developed, high-performance optics, this new lens measures only 25 millimeters long and weighs a mere 140 grams. When mounted on a PENTAX digital SLR camera body, it protrudes very little from the camera's front panel, making it an ideal choice for carry-everywhere, instantaneous snapshot photography.


  2. Versatile wide-angle perspective

    Mounted on a PENTAX digital SLR camera body — including the new K100D — this lens offers an angle of view equivalent to 32mm in the 35mm format. This versatile angle of view produces natural images with a moderate perspective and an expanded depth of field (or a wide in-focus area), making it ideal for many different types of subjects and occasions, including snapshots, landscape, travel photos, and architecture.


  3. High-performance optics

    This lens incorporates a hybrid aspherical lens in its eighth optical element to effectively compensate for a variety of aberrations, which cause adverse effects on overall image quality. In order to assure high-quality image reproduction over the entire focusing range, it also features a floating mechanism, which is designed to adjust the degree of aberration compensation in relation to the focusing distance.


  4. Limited Lens-series quality for distinctive visual description and a premium appearance

    The PENTAX Limited Lens series is designed for ultimate image reproduction by combining a series of mechanical and numerical evaluations with human assessment of test-shooting samples. True to this tradition, this new lens not only assures excellent image quality, but also produces sharp, clear images with outstanding contrast even at the maximum aperture, because its optical design has been optimized for digital photography. In addition, its lens barrel, hood and cap are all made of a high-grade aluminum material, shaped for perfect proportions and striking beauty.


  5. SP coating to protect the lens against water and grease

    The PENTAX-original Super Protect (SP) coating is applied to the front surface of the lens. Through a vapor deposition process, the lens surface is coated with a special fluorine compound to repel dust, water and grease, making it easy to wipe off fingerprints and cosmetics.


  6. Digital SLR-exclusive design

    This lens is exclusively designed for use with the PENTAX digital SLR cameras, with an image circle perfectly proportioned to the CCD size (23.5mm x 15.7mm), and optics optimized for digital imaging characteristics. Combining high-quality image reproduction with an ultra-thin, super-lightweight design, it is a perfect partner to PENTAX digital SLR cameras.


  7. Other features

    1. PENTAX-developed Quick-Shift Focus System for instant switching to manual-focus operation after the subject is captured in focus by the AF system.
    2. Minimum focusing distance of 20 centimeters for close-up photography.
    3. Dual filter attachment design: 43mm filters on the hood, and 49mm filters on the lens (without use of the hood).
