Overview

The Carl Zeiss Sonnar 140/2.8 C645 is widely praised as an excellent portrait lens, offering typical Zeiss sharpness even wide open and creamy, smooth bokeh described as 'perhaps the best in the business'. Its solid metal build and rock-solid operation are noted, though it is heavy. A common weakness is the relatively long minimum focusing distance, limiting tight head shots. It suits portrait, wedding, and landscape photographers who value sharpness and beautiful background rendering.
