28mm · f/3.5
The SMC Pentax SHIFT 28mm f/3.5 is a rare, all-metal shift lens built like a tank. It offers good to very good sharpness at f/8-f11, but image quality is lower at wider apertures and degrades at extreme shift. Handling is cumbersome due to multiple rings and manual aperture, requiring a tripod. A common wobble at the lens mount is reported. It suits architectural photographers needing perspective control, but is not recommended as a walk-around lens.
