ZEISS 135mm f2 Apo Sonnar ZE Lens for Canon EOS

This high-speed lens excels with its excellent color correction and rendition. Thanks to its large aperture and harmonious bokeh, it is perfect for medium distance portrait photography.  The lens design ensures consistent imaging performance throughout the entire focusing range as well as sharpness to the periphery of the image. Its minimum focusing distance is 2.62' (0.8 m).  An "apochromat" lens built with anomalous partial dispersion glass, it will minimize chromatic aberrations for sharply detailed, high contrast images free of color artifacts.  Anti-reflective lens coatings and a deep-black special lacquer treatment on the element's edges reduce reflections and the negative effects of stray light.  A wide rotation angle of 268º enables precise manual focusing.
