The Laowa OOOM is a versatile lens for special tasks. An extremely versatile tool in the hands of a skilled operator. With a focal range of 25-100mm, you can replace several fixed focal length lenses with a single zoom. From breathtaking wide angle shots to epic close-ups of important detail.
A lens made for filmmakers
The stepless adjustment allows for smooth and soundless aperture changes during filming. The focus, aperture and zoom rings feature the popular 0.8 pitch gears used in the film industry, which are adapted to Cine Follow Focus motors.
Super35+ format coverage
The Venus Optics Laowa OOOM lens has been designed and adapted to work with cameras covering the Super35+ format. The design of this lens allows it to work seamlessly with the sensors:
- Red Monstro (6K HD) / RED Gemini (5K HD) / RED Helium (8K HD)
- Arii Alexa Mini (4K UHD)
In addition, with the optional expander it is possible to connect the lens to full frame cameras.
One lens for Arri, Canon and Sony
The Laowa OOOM lens has an Arri PL mount by default, but nothing prevents you from changing it! Canon EF and Sony E mount bayonets are included, as well as the tools needed to change them.
The parafocal lens system ensures that the plane of focus is maintained when changing the focal length of the lens. The object you have focused on will always remain sharp and clear. Never miss the perfect shot again.
Minimised “breathing effect”
An additional advantage of the Laowa OOOM lens is that the “breathing effect” is reduced to unnoticeable values. When changing focus, your composition will remain the same without distracting the viewer.
High brightness, short focus distance
A high relative brightness of T2.9 (constant over the entire focal range) allows you to shoot in very low light. And the extremely short focus distance (60cm from the camera sensor) opens up a wealth of creative composition possibilities for cinematographers.
The OOOM Effect “Out Of Our Minds”
The new lens from Laowa has its own unique character. The image it generates is a combination of modern optics providing excellent sharpness with a nostalgic vintage feel. Beautiful, natural colours, creamy bokeh and unobtrusive contrast are the perfect basis for any film production.
Conversion to full frame
With the 1.4X Expander it is possible to attach the lens to full frame cameras without compromising image quality. The expander converts the zoom range from 25-100mm to 35-140mm. The focal length scale can be switched using a dedicated button on the lens housing. A light loss of approximately 1 EV reduces the lens brightness from T2.9 to T4.
Expander not included
Rear anamorphic adapter
The special 1.33x anamorphic adapter allows you to achieve a wide-angle, cinematic screen aspect ratio (2:35:1) without sacrificing resolution or image quality. Unlike front-mount adapters, the Laowa adapter is attached to the bayonet side of the lens. This solution prevents blue flare and oval bokeh (characteristic of standard anamorphic lenses) from appearing on shot footage. The adapter can also be used with other lenses.
Anamorphic adapter not included
Solid carrying case
Lenses from the professional Laowa Cine range are supplied in their original Peli case. These provide security and peace of mind when transporting every filmmaker’s precious ‘jars’.
