Can it actually resolve enough detail for a 21mp sensor though? Says its designed for 4k cinematography, so who knows!
 
Out of interest, why is it that the Canon cinema gear is so expensive? I understand why a 30-300 f/2.9-3.7 would be, but everything in the range is so expensive? Is it just that they're very low volume production or is there something special about them that would mean people buy them over say average L lenses?
 
Think they have two versions, PL and EF. I'd love to use one :o

Vincent Laforet is holding one in his behind the scenes video for Mobius.

- Cine lenses use T-stops as opposed to F-stops: an F-stop is a simply a physical relationship between focal length and aperture, whereas T-stops measure the actual light transmission (T). Lasers are used to measure the loss in transmission between the front and back of the lens. More elements = more light loss, so imagine how much light would be lost in a complex zoom like that. You can have two f/2.8 lenses and the amount of light they'll transmit will be different, T-stops are more useful for keeping exposures consistent. This means that to have a T/2.8 lens, you'd have to have a physical aperture of say, f/2.4, to ensure that the light transmission meets the spec for T/2.8

- They have no focus breathing, so the FOV doesn't change when you focus like it would on a stills lens

- They're all matched as a set, so lenses will be the same size and have the same colour balance. Again, makes it easier to swap out lenses on a rig and achieve a consistent look

- Better corrected for distortion and other aberrations

Basically, if you thought those Canon L or Leica lens making videos had strict tolerances, they're nothing compared to how precise making a cine lens is.
 
At this rate they're going to re-release the 85 1.0 L except in cine spec, with proper sharpness, 0 colour aberrations and a £50,000 price tag... I'd totally buy it.

They have far less optical defects than consumer SLR lenses, are a higher build quality, have better Manual focus systems, are highly calibrated T-stops, and they are low volume.
