Featuring the latest HD Coating to further upgrade image quality, and a totally redesigned body

The development of this new zoom lens was based on smc PENTAX-DA FISH-EYE10-17mmF3.5-4.5ED, while conducting a thorough review of lens coatings. The high-grade, multi-layer HD Coating has been applied to the optical elements for high-contrast images with edge-to-edge sharpness and free of flare and ghost images. The exterior has been totally redesigned to match the design of the latest PENTAX K-mount digital SLR models, and also to make its lens hood removable. When mounted on a PENTAX K-1 or PENTAX K-1 Mark II camera body, the photographer can remove the lens hood to produce nearly circular fish-eye images.
