- 22 glass elements in 17 groups, with six Super ED Lens elements and two ED Lens elements.
- T2.9 aperture across the entire zoom range which facilitates the increasingly popular style of bokeh effect with shallow depth-of-field.
- The focus ring features a rotation of a full 200 degrees to facilitate precise focusing. All operation Rings have a gear pitch of 0.8M, the same as all other Fujinon Cine lenses.
- The front focusing group of lens elements and the zooming group of lens elements are driven independently to suppress focus shift while zooming, which eliminates the need to re-focus after zooming.
- Only one matte box between the lenses is needed with an 85mm front diameter. Only one filter size between the lenses is needed with a filter thread of 82mm.
