Pentax 85mm D FA f/1.4 ED SDM AW

This large-aperture, medium-telephoto lens is the second fixed focus lens of the new-generation PENTAX Star () lens series. Designed for use with PENTAX K-mount DSLRs, this series boasts the highest imaging performance out of all the PENTAX lenses.

The Star series is the top of the range for PENTAX lenses, so when developing the new generation, PENTAX conducted an extensive review of its in-house standards, demanding the highest performance, even for use with future PENTAX DSLRs, which are expected to deliver even higher image quality and better performance than current models. Developed in pursuit of ultimate image quality, this new lens delivers superb imaging power, without relying heavily on the image sensor or image processor. The photographer can enjoy the entire process of taking a picture by viewing the subject directly with sharp and clear detail through the camera’s optical viewfinder

In order to ensure the exceptional imaging power demanded for the new-generation Star series, this new lens incorporates high quality Super ED (Extra-low Dispersion) glass optical elements and an aspherical optical element to compensate for various aberrations whilst keeping them to a minimum — in particular, to reduce axial chromatic aberration effectively and prevent the generation of purple fringing in backlit situations. It also reduces distortion to nearly zero at a focusing distance of four meters – a serious concern for portrait photographers. In addition, PENTAX has also developed a new SDM ring (Supersonic Direct-drive Motor) exclusively for this new lens, resulting in flawless, high-speed autofocus operation, while incorporating an exterior design that provides a secure grip, facilitating manual-focus operation. This new lens is designed not only to assure the highest imaging power currently possible, but also to enhance the joy of photography.
