Sigma Aizu Prime 65mm T1.3 Cinema Lens with E-Mount
Overview
The Sigma Aizu Prime 65mm T1.3 Cinema Lens with E-Mount is a telephoto spherical prime that covers Vista Vision sensors. Telephoto focal lengths compress perspective and throw backgrounds well out of focus, letting camera operators isolate a subject from a busy environment or reach action at a distance. A T1.3 maximum aperture puts this among the fastest cine glass available, giving very shallow depth of field and workable exposure in low light, and the lens closes to T22. It uses an E-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.
Features
Key Features
Telephoto Vista Vision Coverage
The lens covers Vista Vision sensors, projecting a 46.3 mm image circle. A telephoto field of view compresses distance and lifts a subject off its background, suiting clean singles and action reached from further back.
T1.3 Maximum Aperture
T1.3 puts this among the fastest cine glass available. Depth of field wide open is measured in inches at close range, which demands an experienced focus puller and rewards one with separation no slower lens produces. It closes to T22.
270° Focus Throw
Its 270° focus throw sits in the standard range for cine glass, spreading distance marks far enough apart for repeatable pulls without making a full rack slow.
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.
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.

Mount & Rig Integration
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.
95mm Front Diameter
The front element measures 95mm, which fits a compact matte box directly and steps up to a 114 mm clamp with an adapter ring. Matte box fit follows from this measurement rather than from the filter thread, since the clamp grips the outside of the barrel.
