Flexible 25-180mm Range with 7.2x Optical Zoom
The 25-180mm focal range offers excellent flexibility for professional cinema and broadcast camera operators.
At 25mm, the lens is useful for establishing shots, interiors, and wider scenes. At 180mm, it can isolate more distant subjects and important details.
The 7.2x optical zoom ratio is particularly convenient for live events, documentaries, sports, and fast-paced situations where frequent lens changes are impractical.
Full-Frame Coverage and 8K-Ready Optical Design
Built for High-Resolution Cinema Production
The Laowa Ultima FF lens provides full-frame coverage through an image circle measuring approximately 43.2mm in diameter.
Its optical system is designed to accommodate the resolution demands of professional 8K video production with appropriately configured cameras.
The ARRI PL mount allows integration with compatible professional cinema camera systems and suitable adapters.
Sensor recording dimensions should remain within the specified image circle for the intended coverage.
Constant T3.8 Aperture Across the Entire Zoom Range
The lens features a constant T3.8 maximum transmission aperture throughout its 25-180mm focal range.
This helps keep exposure consistent when changing focal length without adjusting the iris.
Its iris range extends from T3.8 to T22, with a fully closed position provided by the aperture mechanism.
The 11-blade iris contributes to smooth and natural-looking out-of-focus background rendering.
Parfocal Zoom with Minimal Focus Breathing
The Laowa Ultima features a parfocal optical design engineered to maintain focus while zooming between different focal lengths.
This performance is valuable in live broadcasting, documentary work, and event coverage, where an operator may transition from a wide shot to a close-up while recording continuously.
The lens includes a back-focus adjustment mechanism for calibrating parfocal performance as required.
Its low focus breathing design also helps minimize changes in framing when adjusting focus.
Advanced 26-Element Optical Construction
The Ultima FF features an optical formula consisting of 26 elements arranged in 20 groups.
This design supports the versatile focal range while addressing the optical requirements of high-resolution broadcast and cinema acquisition.
The maximum close-up magnification is 0.2x, corresponding to a reproduction ratio of approximately 1:5.
The lens is intended for professional cine zoom work rather than true 1:1 macro reproduction.
Cine-Standard 0.8 MOD Focus, Zoom and Iris Gearing
Dedicated geared control rings provide separate adjustment of focus, zoom, and iris, all using the industry-standard 0.8 MOD cine gear system.
These rings are compatible with suitable follow-focus accessories and external lens control motors.
The focus throw is 180°, the zoom throw is 110°, and the iris throw to T22 is 36°.
The iris mechanism also supports a fully closed position with an overall rotation of approximately 42°.
Precise Manual Focus with Dual Distance Scales
The lens uses a fully manual focusing system, providing direct control over focal adjustments for camera operators and focus pullers.
Its minimum focusing distance is 1.2m, measured from the camera's sensor plane.
The focus ring includes metric and imperial distance markings, making the lens practical for production crews using different measurement systems.
The geared interface enables suitable external follow-focus systems to control focus during recording.
Optional Movcam Servo Drive Compatibility
The Laowa Ultima FF can be used with a separately available compatible Movcam servo drive.
A suitable servo system enables more convenient zoom operation for ENG-style shooting, live television, and other fast-paced production workflows.
The lens remains fully usable through its manual cine control rings without a servo.
The servo drive is sold separately and is not included in the standard package.
110mm Filter Thread and 118.4mm Front Diameter
The lens features a 110mm threaded front filter mount for compatible screw-in filters.
The 118.4mm front outside diameter is a separate physical measurement from the filter thread.
The outside diameter should be considered when selecting compatible clamp-on matte boxes and front-mounted cinema accessories.
Verify the mounting dimensions of any accessory before attaching it to the lens.
Professional Construction with Included Support Foot
The Laowa Ultima FF has an overall length of approximately 300mm, a 118.4mm front outside diameter, and a listed weight of approximately 4.04kg.
The included lens support foot provides a 3/8"-16 mounting interface for compatible professional support systems.
Proper lens support helps distribute the equipment's weight and prevents unnecessary stress on the camera's lens mount.
