Pentax SMC-DA 17-70mm f/4 AL (IF) SDM

Ultra-Wide to Medium-Telephoto

Equivalent focal length of 26-107mm in 35mm format, when used with digital SLR cameras.

High Optical Performance

ED and aspherical elements compensate for chromatic and spherical aberration.

Exclusive Digital Design

The image circle of the lens has been created to match the smaller image recording area of digital SLR cameras. This ensures precise optical performance ideally suited to the camera's digital imaging characteristics.

SP Coating

SP (Super Protective) coating made of a special fluoride compound has been applied to the front surface of the new lens through the use of a unique evaporation process. As a result, the lens offers excellent water- and oil-repellent performance and makes for easier cleaning should the lens be accidentally smeared with fingerprints or cosmetics.

Quick-Shift Focus System

The Quick-Shift Focus System allows to instantly shift to manual focus once the subject is captured by AF.

Updated Lens Mount

Features the Pentax KAF3 mount, which incorporates electrical contacts to drive the built-in supersonic motor used in autofocusing operation. 1
