Canon EF CN-E Prime Lenses provide the creative choices to fully cover shooting most scenes in Full Frame or Super 35. 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.
