This lens is optimized for video shooting. It minimizes focus shift and optical axis shift while zooming and reduces lens breathing, ensuring a consistent angle of view during focusing. It also features a constant T2.9 aperture across the entire zoom range, allowing for a shallow depth of field and a beautiful bokeh effect.
The lens features three manual operation rings for independent adjustment of focus, zoom, and iris (aperture). This provides intuitive operations and eliminates the time lag typically caused by an electrical mechanism.
The lens uses 22 glass elements in 17 groups, including two super ED lens elements and two ED lens elements. It also incorporates the benefits of a short flange focal distance of X Mount into its optical design to the maximum extent. This results in advanced optical performance despite its compact and lightweight body.
Yes, the lens supports seamless iris adjustment that is free of clicking. This enables precise and silent exposure adjustment while also preventing camera shake.
Yes, all operation rings on the lens have a gear pitch of 0.8M, the same as all other FUJINON cine lenses. This allows the use of all standard third-party accessories for video production.
