The Carl Zeiss Apo Sonnar T* 2/135 is a manual-focus telephoto prime praised for outstanding sharpness, contrast, and build quality, with a metal barrel and hood that feel premium. However, it exhibits noticeable longitudinal chromatic aberration and slightly nervous background bokeh. Its heavy weight (930g–1315g) and lack of autofocus make handheld use challenging, especially for fast-paced shooting. It suits studio portrait photographers or tripod users who prioritize optical excellence and can tolerate manual focus.
