This Zeiss 35mm F/1.4 Distagon T Lens for Canon EF continues the 120-year-old Zeiss tradition of optically superb lenses that are built to last--this very fast wide-angle 35mm lens offers all the traditional advantages of Zeiss optics: precise manual focusing with a large rotation angle, unparalleled control of glare and stray light to ensure brilliant images every time, an almost circular aperture that delivers a harmonious bokeh (the difficult-to-define quality in out-of-focus areas that's pleasing to the eye), and robust all-metal precision construction. And it's all at the service of Canon DSLRs with an EF mount.

Very fast f/1.4 lens for low light and for impressive bokeh effects 

Precise focusing mechanism with a large rotation angle--operating a lens manually means controlling the picture with your fingertips. Ergonomics are everything. 

Optimum control of glare and stray light ensures brilliant images--ZEISS lenses are famous for the exceptional quality of the pictures they provide. No matter how demanding the subject, perspectives, colors, and lighting situations are reproduced perfectly - over the entire full-frame image field. 

The almost circular aperture enables a harmonious bokeh in out-of-focus areas--the finely matched properties of the aperture ensure that the effects of out-of-focus areas of the picture are attractively balanced (bokeh).
