14mm · f/2.8
The Pentax smc DA 14mm F2.8 ED (IF) is a solidly built ultra-wide prime for APS-C, with a metal shell and internal focusing. Optically, it delivers high center sharpness from f/2.8, with borders and corners improving by f/8–f/11, but exhibits heavy vignetting at f/2.8 and moderate barrel distortion with a wavy mustache pattern. Chromatic aberrations are fairly well controlled. Its close-focus ability (17cm) is praised for creative close-ups (OutHereInTheField). It suits landscape and close-up photographers who prioritize build and speed over extreme wide-angle coverage, though some found optical performance disappointing for the price.
