Pentax 17-70mm F4 DA AL IF SDM Lens

A more versatile version of a standard zoom lens (equivalent to 26-105 in 35mm terms), the Pentax DA 17-70 f4 AL (IF) SDM Lens utilises the faster and quieter ultrasonic autofocus drive (SDM). The inclusion of the two aspherical lens elements ensure sharp clear images throughout the entire zoom range, while the constant f4 aperture means easier control in both manual and aperture priority modes.
