Overview
The Sigma High-Speed Prime 65mm T1.5 Cinema Lens with EF-Mount is a standard spherical prime that covers Full Frame sensors. A standard focal length sees close to natural human perspective, which suits dialogue and coverage where the framing should not draw attention to itself. A fast T1.5 aperture lets camera operators separate subjects from their backgrounds or get the most out of available lighting when filming in darker environments, and the lens closes to T16. It uses an EF-Mount with manual focus. Standard electronic contacts pass aperture and focus information between the lens and the camera body. The focus barrel is available in either imperial or metric markings.

Key Features
Standard Full Frame Coverage
The lens covers Full Frame sensors, projecting a 43.3 mm image circle. A standard field of view sits near natural perspective, the neutral option for dialogue and everyday coverage where framing should not announce itself.
T1.5 Maximum Aperture
At T1.5 the lens separates subjects cleanly from their backgrounds and gets the most out of available lighting when filming in darker environments. It closes to T16.
185° Focus Throw
Its 185° focus throw is short, racking quickly from close focus to infinity — fast to operate and forgiving for a solo operator, at the cost of finer separation between distance marks.
Imperial or Metric Focus Scale
The lens ships with either an imperial or a metric focus barrel. The scale is fixed at purchase rather than switchable, so a rental order or a set build has to specify which one is needed.
Service-Interchangeable Mount
The mount can be changed, but only at a service center rather than on the bench, swapping EF-Mount for E-Mount. The swap is a scheduled job with turnaround attached, which suits a permanent change of system rather than moving between bodies on a shoot.
Electronic Contacts
Contacts in the mount pass aperture and focus information between lens and body. The camera records those settings into metadata and can drive the iris electronically where the body supports it.
Focus & Handling
2.1 ft Minimum Focus
Mount & Rig Integration
EF-Mount
The lens mounts via EF-Mount, designed for DSLR bodies and adapting cleanly onto most mirrorless systems, where the longer flange distance leaves room for a simple adapter without corrective optics.
0.8-Pitch Cine Gears
The lens carries 0.8-pitch cine gears, the standard pitch for follow focus units and lens motors. Compatibility with lens control systems lets a solo operator make consistent, repeatable focus pulls, or a camera assistant control the lens remotely.
86mm Filter Thread
The front accepts 86mm screw-in filters behind a 95mm front element. A matte box clamps to the outside diameter instead, which is what most cine setups use to avoid re-threading filters between lenses.
