Pentax 17–70mm f/4 DA AL SDM

Its zoom range covers wide-to-moderate tele, and its constant f/4 aperture is sort of fast. But optical performance at the 35mm focal length is excellent, with no vignetting at all.

Standout Spec: Useful focal-length range. You can shoot scenery, interiors, portraits, and snapshots.
