The Cooke S4 set has a top aperture of T 2 along all the focal range. Produced at the end of the 90s and equipped with a standard PL mount, these lenses are well known for their smoothness and low contrast. They also offer amazingly truthful skin tones and perform very well even wide open.
Optional Uncoated Front Elements for the S4 Series
The uncoated front elements offer more choices to cinematographers, with lower contrast, milkier shadows, flares, streaks and other aberrations that give a vintage look.
Available for each lens in the set.
Light loss is about 10%, so depending on the lens, maximum T-stop is around T2.2 (instead of T2.0) with the uncoated front.
