10mm Ultra Prime

ARRI Ultra Prime 12mm

This lightweight ARRI Ultra Prime 12mm Lens T2.0 (PL Mount) offers excellent image quality and an optical match with the high speed Master Prime family of lenses. A high brightness across the image area, plus correction for color fringing at both infinity and close-focus, were important criterion in the optical design of ARRI’s Ultra Prime family.

All lenses in this set offer a rigid, robust housing. The overall length is constant over the entire focusing range. New focus drive mechanisms designed for this family are sensitive and free of backlash. In addition, the focus and iris gears do not move axially during focusing.

A 9-blade rounded iris design provides a natural, smooth bokeh.
