This Canon EF CN-E Cinema Prime 6-Lens Kit put together by B&H consists of seven Canon EF-Mount CN-E Cinema Prime lenses designed for the film industry. The range of lenses in this kit provides you with the creative choices to fully cover shooting most scenes, and they provide image coverage for full frame and Super 35 sized sensors. The included lenses feature a Canon EF mount, and the kit includes 14mm T3.1, 24mm T1.5, 35mm T1.5, 50mm T1.3, 85mm T1.3, and 135mm T2.2 lenses. The lenses are designed to deliver edge-to-edge sharpness and brightness and provide a cinematic image well suited for the Cinema EOS series and all Canon DSLRs.Each lens features an 11-bladed iris which provides rounded, out-of-focus highlights for a more natural-looking image and consistency when switching focal lengths. The lenses incorporate dual focus markings on each side of the barrel, making it easier to read lens markings from either side of the camera. The lenses all share a consistent form factor, the same 114mm front barrel diameter, gear position, and rotation angle across the family of CN-E prime lenses, minimizing differences as you switch lenses during your shoot day.
