I really like the potential of the CP2 lenses - FF, super light weight, fast speed at some focal lengths, mount flexibility may be useful for use with the new A7RII
Have also seen a few tests and they look pretty good compared with the Ultra Primes.
They seem like the perfect lens for non-feature / hi end TVC filming and of course will cover the Weapon sensor
So how come they are so much cheaper? Seem too good to be true
