Samyang's cinema 35mm for Nikon — the VDSLR T1.5 with geared focus and T-stop.
The Samyang 35mm T1.5 Cine AS UMC is a manual-focus cinema prime from Samyang's Cine lens line for Nikon F-mount cameras. It is derived from the photographic Samyang 35mm f/1.4 design with cinema-specific modifications: a de-clicked aperture ring, geared focus ring with T-stop markings, AS aspherical elements, and UMC Ultra Multi-Coating.
The lens delivers 35mm at T1.5 transmission aperture — slightly more conservative than a strict f/1.4 photographic designation — with aspherical optical elements for improved aberration control, UMC coating for flare and ghosting suppression, a de-clicked aperture ring for smooth video exposure pulls, and a cine-standard geared focus ring. Full-frame coverage.
The Cine AS UMC designation represents a meaningful upgrade over the base photographic design — the de-clicked aperture is essential for smooth in-shot exposure adjustments, and the geared focus ring enables standard follow-focus and lens control systems. The 35mm focal length is a versatile single-lens choice for narrative filmmaking covering wide-normal coverage.
Test the de-clicked aperture ring for smooth, continuous travel without any residual click engagement — this is the primary cine-specific feature and any stickiness will impair smooth exposure pulls. Check the focus ring gear for integrity and smooth travel. Inspect UMC coating. Confirm correct Nikon F-mount coupling and focus infinity accuracy.
