Standard length manual focus prime lens for EF mount cameras.
Functional as still photo lens but optimized for cinema and video shooting with geared aperture and focus rings, de-clicked aperture for smooth exposure transitions and laterally printed aperture and distance markings.
The 50mm T1.5 is part of the DS series of cine lenses, sharing characteristics and features that unify the series and make it easier for users to swap out lenses when shooting video.
DS lenses provide aligned focus and aperture rings so that readjustment of the follow focus is not necessary when switching lenses.
DS lenses print focus scales on each side of the lens barrel for ease of use from both sides of the camera.
