Sigma’s new Cine lens line-up is dressed to impress, with their highest level of optical performance yet, in a compact production quality design. The 20mm lens offers full frame sensor coverage and a wide angle of view, perfect for capturing an immersive field of view. A T1.5 light transmission rating performs beautifully in a range of lighting conditions while also giving you narrow depth of field with smooth falloff. The rotation angle of the geared focus ring is more than double that of still camera lenses giving you high-precision focusing. Its all-metal dust and splash-proof body is made to handle the absolute rigors of daily life on-set, no matter your production size or location.

20mm Wide Angle Prime Cinema Lens

The Sigma 20mm T1.5 FF prime is one of the widest in their impressive new line-up. Full frame sensor coverage and a relatively wide angle of view are excellent for capturing larger scenes, providing an immersive viewing experience with astonishing detail and clarity.

Bright T1.5 Light Transmission Rating

A bright T1.5 light transmission rating has the lens performing exceptionally in a range of different lighting types and scenarios, whether you’re shooting in-studio or on location. This lets you and your crew be more flexible with lighting options, working well for lowlight and changing conditions.

Resolve 8K Images

Sigma’s is known for their ultra-high-performance optical system, and the 20mm Cine lens is no exception, able to resolve incredibly detailed 8K imagery. Advanced computer-based ray tracing has been used during the design process from start to finish. This effectively minimises flare and ghosting while helping to enhance contrast in backlit conditions.

Professional Geared Controls

The position of the geared control rings is standardised across the Cine range so even when you change lenses, accessories and attachments can stay place, streamlining your workflow. The focus ring has a 180° rotational angle, more than double that of still camera lenses, for extremely sensitive and high-precision focusing. The click-less iris ring offers soundless full manual control, contributing to highly accurate exposures throughout the scene.

Standardised Colour Balance

Sigma’s entire line-up of cinema lenses are made to comply with their own CCI standard. This helps ensure consistent performance with identical colour balance no matter which Sigma lens is used in your production. It makes colour correction quick and easy to replicate from one scene to the next.

All-Metal Production Quality Build

The Sigma 20mm T1.5 lens is compact and lightweight, compared to many other cinema lenses. This makes it ideal for an active on-set life. The all-metal body has laser engraved information for great readability and longevity. Extremely robust construction has each ring mount sealed against dust and moisture, ensuring the lens is ready for even the toughest jobs, both in studio and on location.
