the Samyang 50mm T1.5 VDSLR Nikon Full Frame Lens is 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 side-facing aperture and distance markings. The 50mm T1.5 is part of the VDSLR 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. Each VDSLR lens provides aligned focus and aperture rings so that readjustment of the follow focus is not necessary when switching lenses. Also each lens has been tested to match color and contrast for a consistent look and less potential post-processing. Finally, all lenses from this series print focus scales on both sides of the lens barrel for ease of use from each side of the camera.
