I truly hope the price will be more in the 600 euro range rather than 800 to 900. The current 50mm of Sigma is around 440 euro. The 35mm Art went down to around 730 euro.

That would be good, but knowing myself I will sooner or later be tempted by this new offering, especially of the price drops below that of the 35 ;)

Sharpness seems to be very similar to the 35mm. Probably better bokeh.

What didn't you like, specifically? I'm actually having even more fun with this lens on the MkIII than on the MkII although it's harder to check critical sharpness on the Mk III at wide apertures (my Mk II has a precision matte focusing screen). On the Mk II I use manual override to tweak the sharpness at wide apertures, on the Mk III I've set AFMA +8 for this lens.

FYI, I got a matte focusing screen for my MKIII from this site and it works great:
http://www.focusingscreen.com/product_info.php?cPath=21_134&products_id=1193

Thanks for the link! I've bookmarked it for reference if I decide to go that direction. How does your 5D Mk III meter with this screen?

I haven't noticed any metering abnormalities.  I usually shoot in Av with evaluative metering and occasionally bump to +1/3 EV to expose to the right, which is pretty much what I was doing before on a 5Dc with Canon's matte EE-S screen.

And lest anyone consider this off-topic, in my opinion, an upgraded focusing screen is pretty much a requirement if you plan on doing manual focusing with the fast 50's being discussed :)

Moreover, just looking at lens in EF-mount, the Zeiss 50mm f/2 clearly beats the EF 50mm f/1.4 at f/2.

Where are you seeing this?  How does the $1,283 Zeiss beat the Canon 50/1.4?  Here are the numbers at f/2 according to LensRentals:
Canon 50/1.4 = 790 center, 660 average
Zeiss 50/2 = 760 center, 620 average
http://www.lensrentals.com/blog/2012/01/the-great-50mm-shootout

They are close, but the Canon 50/1.4 scored higher.  The Zeiss is arguably better according to charts over at The-Digital-Picture, but again they are close.  Of course, the Zeiss should be better, being 3X or 4X more expensive.

I am seeing this on the MTF graphs and reviews of lenstip and photozone. They are, from my expirence at least, trusted sources. Also, the fact that it is more expensive doesn't affect the fact that it is, according to the graphs, sharper; I haven't talked about value, but only image quality.

The f/2.5mm is a Macro lens it is not a general purpose lens. The 40mm f/2.8 was Canon's entry into a super cheap STM prime for their STM initiative, the 50mm f/1.8 was just a super cheap lens to promote entry level photography with primes, and the 50mm L prime is horrible. The last version was so bad at f/1.0 that they dropped the entire idea, and the new version is equally horrible. At f/1.2 it has lower picture resolution than an iPhone 5. It also has image quality that has to be compared to lensbaby, a plastic lens made to be extremely horrible on purpose for visual effects. The 50mm f/1.2L is one of the worst lenses made by any manufacturer period.

Canon's only non-gimicky 50mm is the 50mm f/1.4. And actually it's a pretty decent 50mm, it actually has more resolution at f/2 than any other 50mm lens in the world released, prior to 2013. It is extremely hard to make a 50mm lens that is fast and most deliver extremely poor image quality. The Canon 50mm 1.4 actually beat out every other 50mm lens on the market at f/2, delivering what I would consider the fastest 50mm aperture with an average resolution of 2400 LPPH or more (which is the minimum resolution I consider acceptable), but it was disappointing to see such a poor focusing mechanism and such poor coatings because it wasn't updated for an extremely long time.

Just because you don't personally use or like a lens doesn't make it "gimmicky". 

The original 50/1.0 lens, which you call "horrible", was almost unique in its time and still makes beautiful photos at f/1.0:  http://www.jessicaclaire.net/index.cfm/postID/263

The 50/2.5 macro is for any purpose you want to use it, not just macro.  It's cheap and sharp, though it has the old buzzy AF motor.  Cheap + sharp + 1:2 macro = a good combination.

The 40/2.8 is a wonderful pancake lens and is a cheap way of shrinking your big dslr and still having really sharp photos.  Brilliant and a joy to use.  Cheap + sharp + very small = a good combination

You're right, the 50/1.8 is "just" a super cheap lens to promote entry level photography with primes.  But wait, that's a good thing.  What's wrong with that?  That actually makes some people very happy.

The "horrible" 50/1.2L which you compare to a plastic Lensbaby has been used for a tremendous amount of professional work.  It is good enough for David Burnett, Sebastiao Salgado and Mario Sorrenti, but not good enough for you?  And this guy seems to make decent photos with it:  http://www.flickr.com/photos/petezelewski/ ... not bad for using what you say is "one of the worst lenses made by any manufacturer period."

As for the Canon 50mm f/1.4 having more resolution at f/2 than any other 50mm lens in the world released prior to 2013 ... not exactly.  That would easily have been the Leica 50/1.4 Summiluxhttp://www.lensrentals.com/blog/2012/01/the-great-50mm-shootout

In the Lensrentals "Great 50mm Shootout", you'll note that both Canon 50/1.4 and 50/1.2L scored higher in resolution than any of the 50's from Nikon, Sigma or Zeiss.  That's pretty good for lenses you consider gimmicky or not good.  Leica scored higher, but Leica is in a much higher price category.

Moreover, just looking at lens in EF-mount, the Zeiss 50mm f/2 clearly beats the EF 50mm f/1.4 at f/2.

... which is a $1200 manual focus f/2 macro lens. Lensrentals clearly shows that Nikkor 50/1.4 beats all of it's price category rivals and Sigma is the sharpest in the center, while the good old plastic-fantastic 50/1.8II would put all them to shame, for the price that is :).
I'm not a pixel-peeper, but I do prefer sharp-cropping over soft-zooming. Any decent lens can produce perfectly good and sharp snapshots. Actually, you don't need a DSLR for that (or anything with a big sensor, you can make bokeh in photoshop these days :) ). 50L is not my dream fifty, nor is the 50/1.4USM. If the new Sigma 50/1.4 is anything like their 35Art, then I'm getting one, but for now - nothing beats my 40.

Of course, I haven't talked about value, but only sharpness. Of course, the Ef f/1.4 is faster, cheaper and have AF, while the Zeiss 50 f/2 MP is sharper, have 1:2 magnification and have a much better build quality and focus ring for MF. They are very diffent produces for different needs and different photographers.

I can only agree with you though; if the Sigma 50mm Art is anything like the 35mm Art, I am also getting one!  ;D

I can confirm that. My manual focus experience since I got the 5D (back in the dark ages) was almost exclusively limited to tripod mounted tilt&shift with live view (and some macro), until I got the Otus 55. With my eyesight, which is not great anymore, but far from blind, it is absolutely paramount to have a better focusing screen to get sharp shots at f1.4. It would really be a shame if I only used this lens at f4 and upwards, because I was not able to focus.

So Canon; Please listen; Make us happy and give us the proper focusing screens for the 1DX and all its unborn relatives.

+1 this is exactly why I hold onto my 5DII with super precision matte focusing screen.  This despite LiveView and AF...I like to SEE that my lens is in focus, especially with the f/1.2 lenses :)

What I do love about this anouncement is the audacity! Sigma is shameless. They should be content with their inferior position in the market place, but no, - for the couple of last years they have gone hunting :) It reminds me of a classic ad for a US car rental company in the eighties... "We know we are number two, therefore we try harder"

Good one!  And let's not forget that Canon used to be number two, to Nikon.  It was their audacious move to the auto-focus EF mount that catapulted them to number one.   :)

That, the fluorite elements and being cheaper (though it seems hard to believe today).

All the rumors are pointing to Canon releasing a 50mm f/1.8 IS to replace the current 50mm f/1.4. I have no interest in image stabalization at the 50mm focal length so I am inclined to go with the Sigma and if it is as good as the Sigma 35mm, it may have better IQ than the new Canon 50mm.

I think Sigma scored a home run with this lens

I love the 50 1.4 when it doesn't miss focus and it's at f/2 or higher. If the Sigma is better and priced at around $600-700 (or less) I would seriously consider it. It can't be less durable than a Canons 50 1.4. I've had to get it repaired once and always use a lens hood since (I set my bag down too hard and knocked something loose).  I'm just glad there is some competition.

You are not wrong.  As beaten to death earlier in this thread, some folks value IS and others value speed. 

I think Canon and Sigma's new 50mm lenses will be both be hits... just with different groups of people.

Sharpness, MTF curves - these are not the most important things for a 50mm lens.
Colour, contrast and clarity are far more important.
This is why the 50mm 1.2L is so loved by those that use it often.
If you can't get sharp photos with a 1.2L, then YOUR technique is not right for this lens.

I'd love to try this new Sigma lens, as the recent Sigma's I've bought are really very good indeed and should give a bit of a hurry up to Canon and Nikon.
