    Overview

    The Pentax 10-17mm F3.5-4.5 fisheye zoom offers a unique 180-degree diagonal field of view at 10mm, ideal for creative perspectives. Optically, it delivers excellent sharpness at 14mm and 17mm, with good performance until diffraction at f/22. Chromatic aberration is well controlled at most apertures but can show purple fringing at 14mm wide open. Build includes an integrated hood, no filter threads, and compatibility with APS-C and full-frame (with vignetting). It suits Pentax users seeking a versatile fisheye for dramatic, wide-angle shots.
