The Tokina 40mm T1.5 Cinema Vista Prime Lens, with a PL mount and focus scales marked in feet, provides an image circle that more than covers full-frame sensors and is designed to provide sharp images, even when up to 8K resolution. This 40mm focal length lens shares the same form factor, lens gear position, focus rotation, and front barrel diameter as the other Tokina Cinema Vista prime lenses. This makes on-set lens changes a fast and efficient operation. It features a maximum T-stop of 1.5, useful when shooting in low-light situations or when you want to capture that exceedingly shallow depth-of-field look.
The 9-bladed iris provides round out-of-focus highlights for a natural-looking bokeh. The lens barrel features approximately 300° of rotation from close focus to infinity, giving you a high degree of precision when pulling focus. The lens is designed to minimize focus breathing, and it features geared manual focus and iris rings. Markings on both sides of the lens barrel make it readable from either side of the camera.
