OOOM 25-100mm T2.9

Laowa’s first dedicated cinema lens, the OOOM (Out Of Our Minds) 25-100mm T2.9 is the ideal zoom lens for the cinematographer looking to jump from still photo lenses into the world of cinema zooms. Its robust build quality and versatility put it in a class well above its price tag. The OOOM features a constant T2.9 aperture throughout the zoom range, a 270° focus rotation for smooth, precise focus pulls, standard zoom, focus, and iris gears, and a 110mm front ring. The OOOM lens includes a default PL mount with standard Canon EF and Sony E mount, all packed neatly in a custom foamed travel case. The optional Bundle includes the tailored 1.33x Anamorphic Rear Adapter and 1.4x Full Frame Expander.
