Update your cinema lens set with this 135mm T2.2 DSX High-Speed Cine Lens from Rokinon that comes in a Canon EF mount. The DSX continues the line with the same multilayer coating process, industry-standard geared focus and iris rings, and fast T2.2 aperture, and it adds a 9-blade iris for beautiful soft bokeh, weather sealing to keep the moisture out, and focal lengths on both sides for added versatility for focus pullers. This 135mm lens produces 18.8° coverage when used with full-frame cameras. Aspherical lenses render sharply defined images with a minimum of distortion and chromatic aberrations, with a minimum focus distance of 2.62' from the lens. The 9-blade iris also allows you to create up to a stunning starburst when you're stopped all the way down. A removable lens hood provides flare protection when shooting without a matte box, and the lens' threaded front accepts a 77mm filter ring.
