Canon, CN-E Cinema Prime 50mm T1.3 Lens (EF)

The Canon CN-E 50mm T1.3 L F Cine Lens is an EF-mount standard-width lens for Canon's C-series cinema cameras, full-frame EOS DSLRs, and any video-capable camera that accepts EF-mount lenses. The aperture is a fast T1.3 that lets you get superior shots in low light. The diaphragm is made up of 11-blades and is as round as can be, and along with the fast aperture it can produce impressive bokeh and beautiful circular highlights. The diaphragm ring is stepless, super-smooth, and fully manual, even when used with a DSLR, offering an evermore accurate handle.
