Set up your Canon EF cinema camera for portrait or close-up shots with the Sigma 35mm T1.5 FF High-Speed Prime Lens. The lens has an image circle covering a Super 35mm sensor. It has control rings for the focus and aperture adjustment. These rings have built-in dampeners that reduce metallic sounds when they reach the end. The click-less design of the aperture ring prevents noise when adjusting the T-stop value during recording. The focus rotation of up to 180° makes you freely shift the emphasis between subjects standing at long distances. There are Metric scales for the focus printed on both sides of the lens. All control rings have a 0.8 Mod gear pitch to enable the use of different professional accessories. The lens has a 9-blade diaphragm that produces rounded light circles and smooth blur parts in the background. Additionally, the T1.5 maximum aperture facilitates shooting on a base ISO in dim light. The 95mm front diameter makes lens compatible with various matte boxes. You can use the lens in challenging weather with dust and moisture-resistant sealing blocking the gaps on its metal body.
