the EF-mount Canon CN-E 70-200mm T4.4 Compact-Servo Cine Zoom Lens provides 4K and HDR–compatible imaging for Super35-sensor digital cinema cameras. This lightweight zoom s commonly used 70-200mm range can be further expanded using the separately available Canon EF 1.4x III and 2x extenders. Its color characteristics match those of existing Canon cinema lenses, making for smooth intercutting. Another cinematic feature of this zoom is its nine-bladed iris which can be used to produce attractive bokeh (out-of-focus highlights) effects.
