Cooke S4 primes, introduced in the late 1990s, quickly became industry favorites for their signature warmth, pleasing skin rendition, and soft roll-off into focus fall-off. Rated at T2.0, they don’t chase extreme speed but instead prioritize a gentle contrast curve and painterly handling of flares. Their look has often been described as “humanistic,” making them indispensable for narrative features where emotional resonance is key.
