The Canon CN-E 85mm T1.3 LF is a professional EF-mount cinema prime lens engineered for demanding 4K and HD production workflows. Designed for Canon's C-series cinema cameras, full-frame EOS DSLRs, and any EF-compatible video system, this telephoto lens delivers exceptional optical performance with sharp, high-contrast imaging across the frame. The fast T1.3 aperture excels in low-light conditions and enables shallow depth-of-field cinematography, while the 11-blade rounded diaphragm creates beautiful circular bokeh and naturally pleasing out-of-focus areas. With a stepless, fully manual diaphragm ring and 300-degree rotatable barrel featuring dual-sided focus markings, the lens provides precise control and ease of use for professional focus pullers and camera operators. Lightweight and compact, it features a unified front diameter and mechanical construction that matches the CN-E 24mm and CN-E 50mm lenses, allowing seamless accessory compatibility and quick lens swaps during production. The precision glass design minimises focus breathing for consistent framing during focus transitions--critical for professional cinematography.
