200mm · f/2.8
The Carl Zeiss Jena Sonnar 200mm f/2.8 is praised for being very sharp wide open with exceptional resolving power. Its bokeh is described as very beautiful (Yu-Lin Chan). However, the lens has a tight focusing ring (though re-oiling helps), a minimum focusing distance of 2 meters, and a limiting magnification ratio, often requiring extension tubes for close-ups (Yu-Lin Chan). It is heavy and challenging to handhold (Yu-Lin Chan). This lens suits photographers seeking sharpness and beautiful bokeh in a telephoto, who can manage its weight and focusing limitations.
