The Canon CINE-SERVO 25-250mm T2.95 Cinema Zoom Lens combines the flexibility of a cinema lens with the functionality required for broadcast production. Designed for Super35mm cameras, it delivers 4K optical performance, a versatile 10x zoom range, and a detachable servo drive unit that supports both cinema-style and ENG-style workflows. Its compact design and advanced control options make it suitable for documentaries, live productions, television, and cinematic content creation.
10x Zoom Range with Built-In 1.5x Extender
Cover a wide range of shooting scenarios with a 25-250mm focal length and 10x optical zoom. The integrated 1.5x optical extender expands the telephoto reach to 375mm, providing greater flexibility for distant subjects while maintaining image quality.
4K Optical Performance
Built to support modern cinema and broadcast productions, the lens delivers 4K-ready optical performance across the entire zoom range. Canon Cinema EOS color science helps produce consistent color reproduction and sharp detail from the center to the edges of the frame.
11-Blade Iris for Smooth Bokeh
The 11-blade aperture design creates natural-looking background blur and smooth out-of-focus highlights. The clickless iris ring allows seamless exposure adjustments during recording, making it ideal for professional video applications.
Detachable Servo Drive Unit
Switch easily between broadcast and cinema workflows with the removable servo drive unit. It provides remote control of focus, zoom, and iris functions while supporting a variety of industry-standard lens control systems. The unit can be detached and reattached without alignment adjustments.
Compact Design for Professional Production
Despite its long zoom range and T2.95 aperture, the lens remains compact and lightweight at approximately 6.7 lb. Its portable design makes it well-suited for shoulder-mounted operation, location work, and mobile production environments.
16-Bit Metadata Output
Integrated 16-bit encoder outputs provide accurate lens position data for virtual production and studio systems. This allows precise synchronization between camera movement and virtual environments for advanced production workflows.
Built for Broadcast Reliability
Designed with Canon's broadcast lens expertise, the lens features a durable chassis built to withstand demanding production environments. Weather-resistant and shock-resistant construction helps ensure dependable performance in the field.
Macro Function and Flange-Back Adjustment
The lens includes convenient flange-back adjustment and macro shooting capabilities, allowing users to fine-tune performance and capture close-up details with ease.
