15mm · f/2.8
The Carl Zeiss Distagon T* 2,8/15 ZM is a manual-focus ultra-wide lens offering exceptional sharpness and contrast, with strong corner-to-corner resolution. Optical weaknesses include noticeable vignetting and color casts, though these are correctable with the included central density filter. Build quality is superlative, with a metal body and smooth focusing, but the lens is relatively large and heavy, and the lens cap can be unreliable in cold weather. It suits photographers who prioritize extreme wide-angle perspectives and can work with manual focus, particularly for landscape, architecture, and creative compositions.
