The first cinema zoom from Laowa

The OOOM 25-100mm T2.9 is the first cinema zoom lens from Venus Optics Laowa. It covers a 4x focal range from 25mm to 100mm with a constant T2.9 aperture. The optical design uses 20 elements in 16 groups. Interchangeable PL, EF and FE mounts are included for broad camera compatibility.

Cinematographers needing a parfocal all-in-one lens

This lens suits cinematographers who want a single parfocal zoom for narrative, documentary or solo productions. Super35+ coverage works on 4k UHD Alexa Mini and 8k Red Helium without vignetting. A 1.4x expander can extend coverage to full frame. Buyers who need autofocus or built-in image stabilisation should look elsewhere.

Constant T2.9 aperture across the zoom range

The aperture stays at T2.9 from 25mm to 100mm, allowing consistent exposure while zooming. Focus throw is 300°, zoom throw is 163° and iris throw is 50.5° for precise, repeatable control. Focus breathing is controlled to a minimal level so composition remains stable during focus pulls.

Questions about this item

How do I verify the lens is parfocal after mounting it?

Zoom through the 25-100mm range while focused on a subject; the focus should hold without shifting.

Which mounts are included and must I buy any separately?

PL, EF and FE mounts are supplied; no additional mount purchase is required.

Should I choose the 1.4× expander or shoot native Super35+?

Shoot native for Super35+ coverage on Alexa Mini 4K UHD or Red Helium 8K HD; add the 1.4× expander only when you need full-frame coverage.
