The Pentax DA* smc 55mm F1.4 SDM Lens is a member of the exclusive Pentax DA Star series, developed as part of Pentax’s pursuit of the highest image quality, and are designed to deliver the top optical performance of all Pentax interchangeable lenses. Combining a host of advanced technologies including super-low-dispersion optical elements, extra-low dispersion (ED) optical elements and Pentax-original lens coatings, they assure outstanding image description with clear, high-contrast images, even at edges of the image field.
Featuring a set of special seals, this lens features a reliable dust-resistant, water-resistant construction to prevent intrusion of dust, water and moisture into the lens body.
The Pentax-invented Quick-Shift Focus system allows instant switching to manual-focus operation, after the subject is captured in focus by the camera’s autofocus system.
The front surface of the optics is treated with the Pentax-original Super Protect (SP) coating. Applying a special fluorine compound to the lens surface through a vapor deposition process, this coating effectively repels dust, water and grease, making it easy to wipe off annoying stains such as fingerprints and cosmetic marks.
When mounted on a Pentax digital SLR camera body, this medium-telephoto lens offers a focal length of 84.5mm in the 35mm format. Coupled with its large F1.4 maximum aperture, it is ideal for portraiture applications.
An Aero Bright Coating enhances image-description performance by effectively reducing reflections over a wider wavelength range. Compared to conventional multi-coatings, this new coating greatly improves light transmittance in the lens, while drastically reducing flare and ghost images that deteriorate image quality.
A combination of the latest optical design and a round-shaped diaphragm assures soft, beautifully obscured out-of-focus description, maximizing the advantage of a large-aperture lens in shallow depth-of-field applications.
Super-low-dispersion optical element is incorporated into the optics for effective compensation of a variety of aberrations.
The advanced SDM mechanism assures extra-smooth, super-quiet autofocus operation using a supersonic motor installed in the lens body. Thanks to its SDM-exclusive autofocus system, the lens is designed to be quite compact, despite its large maximum aperture.
