Pentax DA Fisheye 10-17mm f/3.5-4.5 ED
A 10-17mm focal range delivering a 180-degree field of view at the wide end, combined with an ED element for chromatic aberration control, makes this compact 323g lens stand out. The HD and SP coatings suppress flare while the demountable hood enables near-circular fisheye images on full-frame K-series bodies, and weather sealing adds durability. With a 14cm minimum focus distance, this lens is best for Pentax APS-C photographers shooting immersive landscapes and exaggerated close-up perspectives.
