Description — Venus Optics 25-100mm T2.9
The Venus Optics Laowa OOOM 25-100mm T2.9 Cine Lens is a professional Manual Focus zoom lens purpose-built for Cinema / Video production. With a focal length range spanning 25mm to 100mm, it offers a flexible 4x zoom capability within the Standard focal length classification. The lens carries a maximum aperture of T2.9, the cinema-standard T-stop measurement reflecting actual light transmission.
It is built around a PL Mount, one of the industry's most established cinema lens mounts, and its image circle is designed to cover Super 35 sensors. Weighing 2.5kg, the lens has the physical presence expected of a professional cinema zoom. It features no autofocus and no image stabilization, both characteristics consistent with its intended use in controlled cinema production environments where manual operation is the standard workflow.
The absence of a specified filter thread size is worth noting for operators planning to use front-mounted filters.
