Pentax 17mm f/4 SMC Fish-Eye K-Mount Manual Focus Lens Review

The Pentax 17mm f/4 SMC Fish-Eye is a legacy manual focus lens for K-mount cameras, delivering extreme wide-angle fisheye perspective with built-in filters and a hood. At 17mm with full circular fisheye coverage, it's a specialized optic designed for creative distortion and ultra-wide field of view, dating from Pentax's film-era lineup. The manual focus design and older optical formula place it firmly in the vintage glass category, suited for photographers who appreciate the character and hands-on control of legacy glass.

This particular unit is listed in bargain condition from KEH, which typically indicates visible cosmetic wear, though optical and mechanical function should remain intact. At $222, it represents an affordable entry point for shooters looking to experiment with fisheye effects on Pentax DSLRs or adapted mirrorless bodies without investing in modern equivalents. The built-in filters add versatility for film shooters or those seeking in-camera color effects, a hallmark of vintage fisheye designs.
