16–35mm · f/2.8
The Carl Zeiss Vario-Sonnar T* 16-35mm f/2.8 ZA offers high central sharpness across the zoom range, with optimum performance at f/8. Weaknesses include high chromatic aberration and mustache-type barrel distortion at 16mm, plus significant vignetting. Build quality is robust with weather sealing, but the lens is heavy and bulky. It suits landscape and studio photographers needing a durable, fast ultrawide zoom, though rivals may offer better value.
