    Overview

    The Pentax DA* 60-250mm F/4 is a professional-grade telephoto zoom for APS-C, offering a constant f/4 aperture and weather-sealed build. Optical strengths include very good to excellent sharpness from 80-200mm, low chromatic aberration and distortion, and minimal vignetting. Weaknesses include corner softness at 60mm and 250mm wide open. Build quality is excellent with smooth focus and zoom rings, though it is heavy at ~1kg. It suits sports and nature photographers needing a durable, constant-aperture zoom.
