Overview

The Carl Zeiss Planar T* 45mm f/2 is a legacy lens originally designed for Contax G rangefinders, praised for exceptional sharpness and contrast, especially stopped down to f/4. Its all-metal build feels solid and compact at 190g. Weaknesses include visible vignetting wide open and challenging adaptation to mirrorless cameras, requiring specialized adapters that can be expensive and finicky, with autofocus performance limited to bright conditions. It suits photographers willing to work with manual focus or invest in quality adapters for superb optical performance on digital bodies.
