What can I say about the Cook S4s. A lot of people in the film business would say that they are the best film prime lenses in the world. They have a beautiful look, warmer and softer than the Arri Ultra Primes.
T2 is usually fast enough in this day and age, however if you want to go further they do make a faster set, the Cooke S5i lenses which open up to T1.4. However they are significantly heavier and frighteningly expensive!
They are also available in a large selection of focal lengths, please enquire if additional focal lengths are required.
