Cooke S/4i Mini
The miniS4/i Primes (T2.8 to T22 aperture) incorporate everything that today's filmmakers ask for: smaller, lighter-weight lenses that offer the same resolution, optical quality and reliability as the S4/i lenses at T2.8 speed. With the speed of the new digital cameras, T2.8 is the new, economical T2.0. The Mini S4/i’s are interchangeable with the S4/i and 5/i lenses for shooting film and digital images up to and beyond a 4K resolution. Current Mini S4/i focal lengths are 18, 25, 32, 40, 50, 65, 75, 100 and 135mm.
