Zeiss is a king when it comes to clean, sharp and superior glass. We all know Zeiss. It's synonymous with lenses. But if you're on a budget and you want quality and accurate representations for lenses, the CP.2 set is a great start. Its a starter kit (in a sense) for filmmakers who are gearing up to be a pro.
They're built solid and have the same focus gear size throughout...making them cinema-ready and easy to swap between lenses. Also, they're decently fast. To be at 2.1 is great for any filmmaker when you need that little extra push for exposure.
