    Overview

    The SMC Pentax Zoom 45-125mm f/4 is a well-regarded vintage lens with superior build quality (caspert79). Optically, it delivers sharpness, good contrast, pleasant bokeh, and decent CA control, though distortion is a noted weakness (caspert79). Its unusual focal range is appreciated by some. It suits photographers who value classic Pentax build and are willing to accept some distortion for overall strong performance.
