This special, limited-quantity lens features a high-grade, fine-textured silver finish for the first time in the
HD PENTAX-D FA★ series.
This lens, along with the D FA★85mm F1.4 and D FA★70-200mm F2.8 lenses, make up a new triple-model lineup; each lens is assigned a unique serial number from 0000001 to 0000600.
Since its silver barrel is also designed to go well with standard black camera bodies, you can couple this lens with any camera body you like, to further inspire your photographic creativity and motivate you to be more actively involved in the photographic process.
A new-generation, high-performance Star-series lens delivering superb imaging power and exceptional resolving power
This large-aperture, single-focus standard lens is the newest model in the acclaimed PENTAX Star (★) series — the lineup boasting the best imaging performance of all PENTAX lenses for use with K-mount digital SLR cameras. The lens delivers the superb imaging power demanded of a new-generation, high-performance Star-series lens, assuring exceptional resolving power from the center to the edges of the image field, even when set to open aperture.
Thanks to PENTAX-original lens coating technologies — including the latest Aero Bright Coating II assuring exceptionally low reflectance, and the high-grade HD Coating — it produces extra-sharp, high-contrast images free of flare and ghost images. Its dustproof, weather-resistant body also makes it extremely dependable and durable for shooting in demanding outdoor conditions.
This lens features a KAF4 lens mount compatible with an electromagnetic diaphragm control system. Cameras compatible with this system are K-1 Mark II, K-1, K-3 II, KP, K-70, K-3, K-S2, K-S1 and K-50. For K-1, K-3 II, K-3, K-S2, K-S1 and K-50, the camera’s firmware must be upgraded to the latest version.
If this lens is mounted on a camera without proper firmware upgrade, its diaphragm control mechanism becomes inactive, making it impossible to obtain correct exposure.
