  • Full-frame coverage with 43.3 mm image circle

Full-frame 28mm T1 cine lens

The Venus Optics Laowa Argus 28mm T1 is a full-frame cine lens built for Canon RF mount cameras. It targets cinematographers who need an ultra-fast aperture for shallow depth of field and distinctive bokeh in short films or portrait videography. Its compact form factor suits run-and-gun shooting styles. The lens delivers a unique aesthetic with smooth focus roll-off.

T1 aperture and 43.3mm image circle

The T1 aperture provides exceptional low-light capability and pronounced subject separation across the 43.3mm image circle diameter. At 28mm the wide perspective captures environmental context while maintaining cinematic rendering. The fixed focal length requires physical repositioning for framing changes. Optical construction uses 14 elements in 9 groups to control aberrations at this speed.

Manual focus cine housing with RF mount

The lens features a robust manual focus design with geared rings for follow-focus compatibility, standard for cinema workflows. Canon RF mount ensures native communication with mirrorless bodies for metadata and stabilisation where supported. The small form factor balances well on gimbal rigs and lightweight cages. Build quality prioritises consistent optical alignment during repeated focus pulls.

Questions about this item

Will the 28mm T1 lens cover the full-frame sensor on my existing Canon RF cinema camera without vignetting?

The lens projects a 43.3mm image circle that fully covers a full-frame sensor on Canon RF mount cameras.

How can I confirm the 14-element optical formula is performing correctly after mounting the lens?

Check for uniform sharpness across the frame at T1 and verify the characteristic smooth focus roll-off and dreamy bokeh described for the Argus series.

Does the box include a Canon RF mount adapter or must I buy one separately?

The lens ships with a native Canon RF mount so no separate adapter is required for RF-mount cameras.
