Will this lens offer image stabilization? I'm guessing, no. crucial for hand held video work~

You'll probably be very interested in Canon's 50 1.8 IS offering that should be out in 2014.

May finally be a good year for Canon 50 mm primes :)

I have made a simple synopsis of the sequence of lenses/lens groups and their type (divergent/convergent).
+ means a convergent lens, - a divergent lens, lens sequences without blanks mean lens groups

                  +- -+ Doppelgauß type
                + +- -+ + Planar type
            + + - -+ -+ +  EF1.2 50
        + - +-+ + +- -+ +- + Sigma 1.4 50 Art
        - - + + + +- -+ - + + Zeiss OTUS 1.4 55
         + - + - + - + - + +   EF 2.8 24 as another retrofocus design with positive first element


Sigma and Zeiss are similar in their complexity and roughly in the number of lens elements. I expect that the Sigma is much more comparable to the Zeiss OTUS in terms of IQ. But the Zeiss might have an advantage because it uses 6(?) lenses made from different special glass types while the Sigma has only 4 LD glass lenses perhaps of the same glass type. But this might result in a marginally better IQ compared to the Sigma.

But ... truly let's see real images to discuss the IQ!
TOOLS: EF-S 10-22 | 60 || EF 2.8/24 | 2.8/40* | 2.8 100 Macro* |2.0/100 | 4.0/70-200* | 5.6/400* || 2 x 40D | 600D | EOS M  [* most used lenses]

I loved my 50mm f1.8 but I was ambivalent to the f1.4.  I wanted to love it.. but I just couldn't. 

If the sigma is amazing, I'm in.  35 is too wide for me and 85otoo long.  Goldie locks.... don't care... but I will wait a year or two for the  50 to come down in price the was the 35 has.  699 New... on sale... thank you very much.

Great news even if they fall short of this ambitious target. I will settle for 50L-type resolution :) Just hope the AF is up to the task. My first 35 Art had erratic AF and a faulty AF motor that died in a couple of days.

If the 35 1.4 Art, 50 1.4 Art, and 18-35 1.8 Art wont put some pressure on Canon's lens developers, then I don't know what will. :P

Well I guess it's like how Sony's Exmor sensor doesn't put pressure on them.

Canon likes to think they exist in isolation.

I hated the 50 1.8, and find the 50 1.4 much better. But I am hoping for a new sharp-wide-open 50 1.4 with IS. I'd settle for a well-made sharp 50 1.8 IS.

my gut feelings predict that 2014 is going to be a revolutionary year within photographic equipment. I am ABSOLUTELY sure that Canon will surprise us soon, but will the surprise be as "reasonable" as Sigma? It remains to be seen.

Based on the reports so far, and my experience with the 35mm 1.4 Art, I'm looking forward to giving this lens a good working over when it comes out. 

I have had my Canon 50 1.4 since the mid 90's, and loved it in the film and early digital days.  But over the years, as my L lens inventory grew, I used it less and less.  It's sharp enough in the mid apertures, but wide open never has really satisfied me, especially in the last few years when the 5D II and 5D III showed its weaknesses.  When I got my 35 1.4L around the turn of the century, the 50 1.4 has pretty much sat in my bag, with a 28-70 and then 24-70 L zoom handling the focal range at mid apertures. 

I like the 35 1.4 Art so well that I'm seriously considering giving up my 35 1.4 L.  I'm keeping the Canon for another year or so while I see what Canon does for an encore, and while I see what the long-term reliability is for the Sigma.  Right now, I'm really pleased with every other aspect of the lens, including all AF-related areas of performance.

Again, if this 50mm 1.4 from Sigma is anything like the 35, I'll be a happy camper.  For sure the Canon 50 1.4 will be gone in an instant.  It is a necessary evil at this point, even though I love a large aperture 50mm from an artistic standpoint.

How about this... I love my f1.8 compared to the kit 18-55 is, the 75-300, and the 55-250.  When I got around to getting the f1.4, i had a 24-105, a 100m L and I'm drawing a blank on what else. But it wasn't add impressive by comparison.

Any one know what the MSRP on this lens is going to be? Don't want to get excited over a lens I can't afford.  :-\

Certainly sounds excitingly promising. Although setting the bar THAT high may be a dangerous game. It can easily lead to expectations not met, that otherwise may have been well met. But it certainly sounds like the 50 1.4 and 50 1.2L and all the rest, other than the Otus, will have nothing on it.

Did someone say Leica X Vario?  It was over-hyped to hell and while it turned out to be a decent camera (based on the reviews I've read) by the time the announcement was over no one was interested.

Then again, Zeiss wasn't exactly humble about the Otus, but it certainly lived up to the hype and then some.  I think much of the hype will disappear if it streets north of $1,000 and/or has poor bokeh or other shortcomings.

That will be good enough for me. My first 50mm lens!

Been wanting one for ages, but didn't want to deal with the shortcomings of the current offerings.
