The ‘C’ designation in the C Sonnar T* 1,5/50 ZM name means both ‘compact’ and ‘classic’. The lens design and aperture geometry reflect its predecessor from the 1930s, the Sonnar 1,5/50, which was the fastest standard lens of its time. The excellent flare control inherent of the Sonnar lens design is further optimized with the ZEISS T* anti-reflection coating. This lens stays true to its heritage, physically resembling the lenses of the past. With its fast aperture, taking photographs with a beautiful ‘bokeh’ that reflects the ambiance of the golden age of rangefinder photography is as simple as pressing a button.
