Nothing like a bit of Screamo to start the morning.

Maybe Canon has decided to finally make some pro-grade lenses to go with the 7D, and is waiting until they can launch both at once.
All the Pro grade lenses (the "L" lenses) will work on the 7D. Do you mean that they will make pro grade EF-S (crop sensor) lenses? To do that, they will need a pro grade body. A 1Dx with an APS-C sensor.
It's not THAT revolutionary, Olympus have had a 14-35mm F/2 for their DSLRs for a good while and that's unbelievably good quality. I know a professional press photographer who shoots Olympus specifically for that lens.
I don't think Canon would invest their money in pursuing a lens like this, unless Nikon came out with one. I feel Canon would rather make more Rebels with no upgraded features than invest in their devoted/professional crop body shooters. Canon like to deal in extremes, ignorant amateur or needy professional.
A side issue, but I thought you shouldn't ever do this as it can damage your camera?
I always thought the reason you should power off a digital camera when changing lenses is that when power is on the sensor is charged and will draw dust to it.
However when we use a zoom such as the 24-105 this pulls air in and out of the camera - which is probably why if you just use primes your sensor gathers less dust. Just a thought.
So Zeiss has cracked the high quality normal prime mystery that has eluded all other manufactures for decades.
The question is, now that the cat's out of the bag, will Canon fire back with a 55mm 1.4L?
Yes, I see a bit of green in the CO and a bit stronger blue in the LR. I'm sure one could mess with them to make them identical, but my exercise was first to see if CO would do what Stephen did in LR, and the answer for me is yes. Then the exercise for me turned to learning to embrace the chiaroscuro, and I learned alot about that from your nice shot and Stephen's nice render. So thanks to both of you for the inadvertent lesson for me!
 And I'm pleased as can be to know that I can shoot at this ridiculous ISO setting and there are at least two editors, probably more, that can deal with it to at least some useful degree. Pretty amazing tech.
There's actually a solution to that...avoid shooting moving subjects below EV -2 with a slow or long lens without a tripod, and you won't need to boost the ISO that high.
(EV -2 is much too dark to read, so it's not like this is a radical concept....)
Here's one I did when experimenting the camera when I first bought it. 24mm, 1/25, f/1.4, ISO 102000. All processing done with Lightroom. The light sources is from a street light about 150 feet outside the house. I could barely see her. The AF assist lamp from my 580EX solved the focus issue.
The Zeiss CP's are made in Germany from hand picked glass. The rejects go into the Zeiss Glass made by Cosina in Japan
It appears that your 5D3 has the same issue that mine does... in the far bottom right corner of the image it has a more purple hue than it should. It is more noticeable in your NR 25 image. On my 5D3 it is most noticeable at ISO 12,800 and above, but sometimes at ISO 6,400.
Yes, I see it in both CR2 raw files I uploaded as well (taken moments apart), but it mostly is gone when LR opens it with default settings...but I hadn't noticed that before...
Anyone else seeing these at very high ISO/low lighting?
Oh yes it does really look great...time to go LR for me. I did everything in DPP until now...That is quite a great RAW converter and denoise software as I can see.
