Zeiss Apo Sonnar T* 2/135 ZE Canon mount lens review: Ultra-high performer

Introduction Following the withdrawal of Contax reflex cameras from the market, Zeiss, as lens developer to the system, re-established production in Japan by modifying some of the previous optical designs to fit Pentax, Nikon and Canon models. Today the line consists of 13 models with the Sonnar T* 2/135  (135mm f2.0) being the latest addition (not counting the new Otus range) though the firm now only supplies models in Canon or Nikon mount. This newly designed high speed ‘Apo’ model has 11-elements arranged in 8-groups and features a ‘floating elements’ design for improved sharpness at close range.
