Carl Zeiss has announced the Apo Sonnar T* 2/135 telephoto lens, which it will be showing at the Photokina trade show in Cologne later this month. This premium manual focus optic uses a floating focus system to maintain high image quality at all distances down to 0.8m. It uses anomalous partial dispersion glass elements to minimize chromatic aberrations, resulting in an apochromatic design. This lens will be available for Canon and Nikon DSLRs.
