Overview

The Vivitar Series 1 28mm f/1.9 is a fast wide-angle lens praised for its build quality and optical performance. It features a large rear element and floating element for improved close focus (mflensjunkie). At f/4 to f/8, it delivers very sharp images with terrific color (mflensjunkie). However, some copies may have barrel wiggle. It is noted as one of the fastest 28mm lenses for Pentax systems, though Sigma and Canon also offer f/1.8 alternatives. Suits users seeking a well-built, fast wide-angle lens for stopped-down use.
