Pentax 17-70mm Lens Comparison
Pentax 17-70: Overview
The SMC Pentax-DA 17-70mm F4 AL [IF] SDM (that’s a mouthful) is a somewhat recent addition to the Pentax lineup. It was one of the first lenses to feature only SDM focusing. The lens more or less replaced the older DA 16-45mm in the Pentax lineup, though the latter is still available, albeit at a much lower price. The Pentax 17-70mm is intended as a versatile lens with mid-range features, such as a constant aperture, silent focus and, as with all DA lenses, a good build quality.

What's in the box
The Pentax lens comes with a dedicated bayonet hood and a user manual. The rear cap is the regular Pentax issue covering the electronic pins, and the front cap is of the center-pinch type, allowing easy removal even with the hood in place.
