The Sigma 85mm T1.5 FF High-Speed Prime Lens is the right pick for creating suspense in the scene by framing the subject in close-up. Made for Sony E-mount cameras the lens has dedicated control rings with dampeners for the focus and iris adjustment. The lens scale marks are in feet to let you adjust the picture look precisely. Rotate the focus ring up to 160deg in one stretch for employing focus racking at longer distances. The clickless iris ring ensures a silent operation. Also the 9-blade diaphragm smoothens the blurred parts of the background. You may choose to use different accessories intended for professional filmmaking with the 0.8 module gear pitch. The 95mm front diameter lets you attach a matte box or lens motor to the rig. This Sigma cine lens provides a robust performance thanks to its dust- and water-resistant design. You may swap the Sony E-mount with the Canon EF at an authorized Sigma service center.
