Cine Lenses cost a shit ton of money and are in super high demand right now. A set of Arri/Zeiss CP1 prime lenses will cost around 3-5k apiece. Correct me if I"m wrong, but I'm guessing not a ton of ski filmers are shooting with these. They're heavy, bulky, and expensive, and if you don't have an AC/Focus Puller, they're going to be a pain to work with because of the long focus swing. They're about equally sharp as Canon L glass. Unless you have a really good eye for chromatic aberration, you might as well save your money.
Balls deep, no half-shaft.
