During the last 30 years, Cooke Optics focused itself on the production of variable primes such as the Varotal 20-100mm zoom T 3.1, the 18-100mm T 3, the Super Cinetal 25-250mm T 3.7 and so on. They abandoned the prime lens manufacturing for about 40 years, until in 1998 they produced the new S4 serie.
The full set cover a focal range between 12mm and 300mm with a constant top aperture of T 2 along all the lenses, excluding the 300mm which is T 2.8. The front diameter is 110mm for all the set, so 4x5'6 mattebox and filters are required to avoid vignetting. Weight goes from 1.5 and 4.7 kg and the set is only available with PL mount.
Cooke S4 lenses deliver high end optical and mechanical results with their anti flare layer, minimal distortion, veiling and geometrical aberration when wide open. The image of these lenses is famous for its smoothness and definition, with soft passing from focus to blur, low contrast and warmth color wise. Speaking of which, the delivery of the color is unique and they give outstanding performance on skin tones.
It is important to remark that despite their softness, the Cooke S4 are capable to reproduce perfectly detailed images and it is paramount not to confuse the concept of softness with lack of definition. They actually have the perfect resolution for super35 format.
As all others sets from this brand, also the S4 are designed to perfectly match with all the Cooke set, sharing chromatic response with both the Cooke prime lenses, including the last S5i serie, and zooms.
