In case anybody wants to see what it looks like. Canon's version of converting photo primes to Cinema primes. Very nicely done and of interest to video folks. As best I can tell it's 24 f/1.4 optics inside the housing.

Looks like a beauty. Is this something Canon does for a lot of their lenses?
They've just started this, I think after having watched Zeiss make a fortune changing ZF and ZE to CP.2s. Canon's going to do the 50mm f/1.2 and 85 f/1.2 next, not sure after that. I would suspect the 14mm and 135mm would get a lot of attention, too.
Ok I thought this was more of a need-basis conversion and not their cine prime collection. Never mind then, I have the catalogue shipped with my CPS membership packet.
FWIW, I am **really** hoping that the "entry level" full frame they announce this fall is a video-centric camera.
It would be great to start to see some "trickle down" from the C300/EOS C in terms of image offloading from the sensor (with Dual Digic 5 maybe?), better downsampling, additional codecs (C Log anyone?), 10 or 12 bit color, etc.
Eventually it will get there at a lower price point. I know some things are cost prohibitive from a hardware standpoint. And Canon usually carefully separates what they enable in formware on the lower end.

Definitely the housing which facilitates a better focusing mechanism I believe, and the markings. These Canon Cine lenses seem to have more aperture blades too.

External gears on the housing for focus and aperture control, manual aperture control on the lens, better manual focusing (precision, more detailed distance scales), smooth (non-clicking) aperture transitions, rated in t-stops, and I'd also imagine there won't be any focus breathing as well.
As everyone said on the changes. Also the focus ring rotates about 200 degrees from near to far, making precise focus easier when pulling focus, and the distance scales are very accurate. If you set focus at 12 feet, 12 feet is exactly what's in focus.
The coatings on the elements are a bit different, giving it a slightly warmer look, which is more in line with most Cine lenses. Not of particular interest for photographers, but I've used the CP.2 Macro lenses several times just for the absolute joy of manually focusing so accurately. It's really amazing to feel the difference in the focus ring. Not that I'd pay $5k out of my pocket for one, since I don't shoot video.
$5250 is a bargain compared to the Cine lenses for the C300, which are in the $50K range, but still 2.5-3x more than I would pay for a 24mm since I have little interest in video.

wouldn't it need a new optical design to stop focus breathing? and if it doesn't have that isn't $3000 extra a bit gigantic profit margin just for the new housing even with limited quanities?

The aperture is also calibrated in t stops, which take into account that some light is lost due to being absorbed/reflected by the glass. F stops are simply the size of the entrance pupil compared to the focal length.

This is a cine lens for the C300...or any other EOS-mount camera. (The C300 can be ordered with a PL mount as well, but that doesn't change what this lens is for.)
