Maybe overshadowed a bit by the Nikon release and the 24-70 II there are two new slow wide primes from Canon.
A 24 and 28 f/2.8 with IS. While the predecessors were nothing to write home about I thought the inclusion of aspherics in such slow lenses is quite an interesting development. I obviously have no clue at how these will actually perform and if the stabilization is really the culprit for that effort.
But maybe those are the lenses quite a few have been waiting for. A lens for stopped down landscapes sharp into the very corners.
In any case you now have quite a list of lenses to consider if you want to get a 24mm lens for Canon with warranty.
What I can think of right now:
Zeiss:
25/2
25/2.8
Canon:
24/1.4
24/3.5 TS-E
24/2.8 IS
Samyang:
24/1.4
Glad to see Canon release an updated 28mm prime. It's shame it's not f/1.8 (or even f/2) like the EF 28/1.8. Maybe they'll around to coming out with a 28/1.4 That would certainly make me rethink my camera choices.
I'm excited about the 24mm with IS. Sounds pretty cool to me. I've always liked wide primes, they are my most favorite lenses to shoot with. I just hope it's not too much more than the current 24mm 2.8 (which I believe is a little under $400 new), I can't really justify spending $600+ on a lens like that seeing as I already have a 24-70 2.8... But, this one has IS

I thought about adding it but decided to put it into the more alternative bracket. How well does stopping down actually work with the G adapter?
It works fine except that it doesn't stop down to more than about f5.6, as relative to wide open by looking at shutter speed.
I am sure I could make a small change to the adapter so the aperture lever could travel a little longer to stop down further.
But since I have the ze 21 which I use for landscape instead, I usually shoot this lens wide open or stopped down a little.Also, the lens becomes sharp into the corners by 5.6 so It is still good for landscape if I need it. I agree it is pretty alternative.

It's $850 MSRP... sorry.
The thick lines are measurements taken at 10 LP/mm (low spatial frequency, or low resolution) and the thin lines are at 30 LP/mm, at higher frequency / higher resolution.
The black lines are measurements taken with the lens wide open, and the blue lines are with the lens at f/8.
The solid lines are meridonial while the dotted lines represent sagittal measurements.
Unfortunately it doesn't say what the curves represent.
Bare hyggelig!
What we know about the charts is that they are theoretical as Douglas said, and they ignore diffraction, and MichaD mentioned the line frequencies and apertures.
Here is what Canon say, in "Optical terminology and MTF characteristics"

MTFs from Canon should be taken with a grain of salt, because they're theoretical, so they aren't directly comparable to those from Zeiss, FWIW.
+1 yes a grain of salt because they are theoretical. But comparing them against other Canon lenses gives you a hint
