Overview

The Cooke Datal Anastigmat 25 mm f/1.9 is a vintage cine lens known for its swirly bokeh and good center sharpness wide open, with sharpness improving when stopped down (chris_zeel). However, it exhibits vignetting on APS-C sensors due to incomplete coverage, and corner sharpness drops off, especially at infinity (chris_zeel). Build quality is solid after servicing a stiff focus ring, with smooth aperture operation (chris_zeel). It suits photographers seeking creative, swirly bokeh for close-up work, but not for critical landscape or edge-to-edge sharpness (chris_zeel).
