If this lens retail for less than $1000, Sigma lens production staffs will be on overtimes for years ::)

They formally updated the weight on the web page, btw.  It's been AWOL since it was listed the very first announcement day and then it was unceremoniously yanked.

But it's official:  815 g / 28.7 oz 

- A

you should better refer to the companys page

Weight     815g/ 28.7 oz !!!

But IMHO aceptable for this optical design (13 elements / 8 groups / 77 mm filter thread).

Even the old 50 mm 1.4 DG HSM was at 505g / 17.8oz. Unbelievable the new one would be lighter.

If more reviews come out like SLR Gear's, will Canon and Nikon step up their game or will they just admit defeat? Sigma is making it really difficult it even consider a 35mm or 50mm from another manufacturer.

949 is definitely in my buy it now price range... but I'll wait.  I at least will wait until a 2nd generation just in case the first batch has something stupid going on with it... like the 5d mkiii with their light leak issue.

Good price vs performance ... will wait till the hype settles a bit to see if it really lives up to its hype ... the Sony a6000 also had great hype built up to it, but so far the results aren't as promising.

I jumped in line as well earlier this morning, but I'm still not sure I'll keep the pre-order or keep the lens once I get it.  While the 50L has some issues, I still love the lens and don't know if this lens will be a big improvement for my uses of the 50 prime.  I took another look at the imaging resource samples last night and while the bokeh looks nice, especially compared to many of the previous Sigmas, it's not as smooth as the 50 & 85L.  Now that's being pretty picky and looking at it at 100% magnification, so I'm not sure that's relevant for prints, but the bokeh is one of the main reasons I love the 50L. 

Edit: just found these samples on CNet (http://www.cnet.com/pictures/sigma-50mm-f14-photo-samples/3/) and this one shows some LoCA.  Definitely not APO like Otus, but still not horrendous.

Hrm . . . if the 7Dmk2 comes out, I could be in trouble though.

LOL, I don't think so.  What a bomb for Nikon.  Also, just found more samples of the Sigma - looks like flare resistance isn't quite as good as the 50L, but still not horrible: The Phoblographer (http://www.thephoblographer.com/2014/04/11/sample-images-sigma-50mm-f1-4-ii-art/#.U0f4HqJUhI0) - see 5th sample shot

Definitely going to get this one in 2014.  This will be wrapped under the Christmas tree this year waiting for me to open.  Had the Canon 50 f/1.4, but was not impressed.  Couldn't justified paying the huge price on Canon 50L, but at this price range, it's a definite "YES".

With the 7-year-old 50mmL going for $1600...the new Sigma is a no-brainer for someone wanting a quality 50mm.
I do not care about the size and weight...its going on a DSLR for God's sake. LOL! 
It is sooooo nice to see a normal focal length lens for a FF camera raised to this quality at this price point.  I will definitely be selling off my current Sigma 50mm and buying in on this one sometime this year.  I already really like my current 50mm (I have no AF issues)....so this Art lens should be very special!!!

Here is what I want to know.  How good is it compared to my 100L... does it have a magic bokeh.  I'm quite familiar with the focal range and I used to shooting at shallow depth of fields... but I might opt for the 85L mkii over this 50... I hate making these decisions.

You have and love the 50L, yet are open to switching if it's worth it.

What I really want to see is images that show some of the "drawing" ability of the 50L.  That wonderful delineation.  I would also really like to see some shots that show the transition bokeh.  I don't ever get why so many early product shots from review sites (of large aperture primes) are of either scenics or large objects 10 feet or so from the lens.  Show us some nice portrait type shots or more artistic narrow DOF shots - you know, the kind of shots that people actually buy lenses like this to take!!

Dustin, I agree and here are some slightly better examples from B&H's blog (http://www.bhphotovideo.com/explora/photography/news/unveiled-sigma-50mm-f14-dg-hsm-lens) - samples at the bottom.  The transition bokeh on the shot with the glasses isn't pretty, but I don't think we'll know until we can do a real-world side-by-side comparison, in the way you suggest.  I think it will be hard to top the 50L's bokeh.

If more reviews come out like SLR Gear's, will Canon and Nikon step up their game or will they just admit defeat? Sigma is making it really difficult it even consider a 35mm or 50mm from another manufacturer.

I'm hoping Canon can do a 50mm f1.4 (or even f2) IS, that would be both something new and highly desirable.

They were smart. They knew they needed to keep it under the psychological $1000 threshold, so it seems like a bargain and it is clearly less than the OEM.  But OTOH, they had a ton of built-up demand so they wanted to get close to $1000.   Brilliantly done.

I have no problem with Sigma milking this lens, I'm sure they could use a cash cow right now and if it means they will be better able to produce more fantastic lenses like it then I'm all for it.
Once their sales figures as a whole look a little more like Canon then we can get picky about price.

The allure of a "usable" F/1.4 is just too much.  My Canon 50 F/1.4 works for me, but it isn't crisp below F/2.8.  I've joined the pre-order.  Come on Sigma, don't disappoint me this time.

I read that earlier... Now it just comes down to pulling the trigger.  I think the worst thing in the world is that Amazon had the 35 art for 699 last christmas... so if I wait long enough, I can get the 50 art for 749 new... and that's going to drive me nuts. 

But it is only taking a loss on the lens if I ever decide to sell it... and I'm thinking it is hear to stay just like may 70-200 mkii and my 100L... and it would be nice to have a wide open sharp lens that isn't too long.  The 85 was practically useless indoors, and 35 feels too wide open for me... so 50mm is the goldielocks slice of perfection...

This lens sounds great, but i'm just a little surprised that nobody thinks the price is high at all.
I don't think it's crazy expensive, but it definitely doesn't strike me as the bargain that many people make it out to be.
What lenses are we comparing this with besides the Canon 1.2? Just a thought i'm having, I know the 50mm 1.4 Canon is old and poorly regarded but literally nobody is comparing these two lenses.
I had the old Sigma 50mm 1.4, and I LOVED it, the bokeh was awesome, and it was really sharp(I did have to return my first copy as it was very softttt.) But that lens was $400 new and worked fantastic for me for a couple years.
Is the new Sigma really twice as good as the old one?

What lenses are we comparing this with besides the Canon 1.2? Just a thought i'm having, I know the 50mm 1.4 Canon is old and poorly regarded but literally nobody is comparing these two lenses.
I had the old Sigma 50mm 1.4, and I LOVED it, the bokeh was awesome, and it was really sharp(I did have to return my first copy as it was very softttt.) But that lens was $400 new and worked fantastic for me for a couple years.
Is the new Sigma really twice as good as the old one?

The problem with the canon f/1.2 is that it was sharp enough in the middle... so if you follow the rule of thirds... then you are probably cropping a good deal after the fact.  Also... to have the lens be sharp, you had to stop down to around f/2.8 or so.  Yes it has a magic bokeh per reports... but I'm not going to go into that.

Then you have the sigma... which is sharp wide open giving you an addition 2 stops of light.  It may or may not have a magic bokeh yet... that remains to be seen... and no other lens in this price range or lower can quite compete with the color/contrast/sharpness/and distortion that the sigma is bringing to the table except for the $4000 otus... which after tax, let's say it is $4240. 

So far the only critiques of the lens is that there is some manageable chromatic abberation, it is a touch heavy, and it doesn't have IS. 

I contend that you really don't need IS if you are shooting at 50mm, f1.4, and with the current batch of canon full frame sensors 6400 iso is quite usable.  It isn't quite night vision... but it is solid.

As for being heavy... then go out and buy a 50mm f/1.8 mkii... it is light and it is widely mediocre... well... it is good for the money, but it feels like a toy and there are more than a few that say it fell apart in their hands.

No. The new Sigma is more than twice as good as the old one. 240% better specifically.

If you're asking these kinds questions though I don't think you understand how important this Sigma lens is.

Sigma says it is positioning this lens to not even be remotely in competition with any other 50mm lens on the market. And all reviews have pointed to them being right. What that means is this 50mm lens makes all other non-zeiss competitors obsolete. It's like comparing a Mercedes AMG versus a snail in a race, it's just a different class.

The reason for this is that 50mm lenses have traditionally been of the double gauss (planar) design, which severely limits image quality at fast apertures. It's a very poor archaic design that results in around 4 times worse performance in every image clarity measurement. The reason for this is that to make a double gauss lens properly you would have to put elements inside of the mirror box to make the lens sharp. Because you can't put elements inside your mirror all 50mm lenses prior to 2014 for DSLRs have been soft.  The only upside to the double gauss design is a slightly more compact lens. There is literally no planar lens that performs even passably well wide open. The Zeiss Otus was the first retrofocal normal lens for full frame cameras and it showed there was a night and day difference compared to the double gauss design. The Sigma 50mm ART is the second.

Planar lenses have extremely poor performance wide open, lets use the lens rentals 50mm comparison as an example ( http://www.lensrentals.com/blog/2012/01/the-great-50mm-shootout (http://www.lensrentals.com/blog/2012/01/the-great-50mm-shootout)), which tested 23 planar normal lenses. At f/1.4 planar lenses achieved scores in the 300s and 400s in that test for average MTF50 resolution. For comparison the Zeiss Otus delivers average resolution of 800. That's just under 5 times more spacial resolution than the lens it supersedes, the Zeiss 1.4 Planar, @ f/1.4. (remember we have to square linear resolution data to get normal resolution)

If you look at other points of comparison you can see that planar 50mm lenses scored poorly in haziness/glowiness and purple fringing, and often scored poorly in chromatic aberration, usually by a factor of 3-5.

It doesn't take a genius to see why this is important. We just went from having the sharpest 50mm prime being literally the bottom of the barrel, delivering image quality so poor camera phones from several years ago beat them when they are wide open to having a lens that is one of the sharpest primes money can buy. It's like comparing unarmed chimpanzees with nuclear weapons. The lens doubles or triples everything we know about 50mm lenses at the least. This is the greatest improvement in image quality that has ever happened in DSLR photography.

So to get the single greatest improvement in a class of lenses for only $949 is the bargain of the century. Canon or Nikon would have charged you $3000 and still wouldn't be able to keep these in stock.

To summarise, if Canon want to come out with a killer 50/1.4 lens that will replace their current 50/1.4 (and maybe 50/1.8), it needs to be:
1) cost less than $949 so that it is cheaper than the Sigma 50/1.4 Art
2) deliver better quality images than the 50/1.2L
3) provide at least IS and possibly weather sealing

... wait, no it doesn't ... all that Canon's next 50/1.4 lens will need is this:

1) a red ring around the lens.

and people will buy it in preference to the Sigma, regardless of price or performance.

I think you're being too cynical. Time will tell, but most consumers (not CR forum members) chose what works best for them.
I am hoping I get the Amazon lightning deal for this one (or be blessed with whatever luck JD is blessed...). Although I have to say, CanonPriceWatch is the best thing to have happened (or the worst, depending on your PoV).

Thanks, JD, and I just found another review of sorts:
http://fstoppers.com/sigma-50mm-art-review (http://fstoppers.com/sigma-50mm-art-review)

I read that earlier... Now it just comes down to pulling the trigger.  I think the worst thing in the world is that Amazon had the 35 art for 699 last christmas... so if I wait long enough, I can get the 50 art for 749 new... and that's going to drive me nuts. 

But it is only taking a loss on the lens if I ever decide to sell it... and I'm thinking it is hear to stay just like may 70-200 mkii and my 100L... and it would be nice to have a wide open sharp lens that isn't too long.  The 85 was practically useless indoors, and 35 feels too wide open for me... so 50mm is the goldielocks slice of perfection...

I'm so glad to hear someone else pointing out that 50mm definitely has advantages over 85mm. Earlier I almost posted a rant about one of my (admittedly few) experiences trying to shoot 85mm indoors. Frustrating to say the least.

It depends on the amount of space indoors. But generally the 85mm would be more of a close-up portrait lens for indoors. You have to move around a lot unless you have studio space. The 50mm will allow you to add more than one person in your composition.  But this all may be different for each one of us. I was checking both focal lenghts and have decided that I will go for 50mm first. Looking forward to the Sigma release

I'd probably put it in the market now... I would presume that people will try and sell it once they get their hands on the sigma art and do their side by side comparisons... but WE know it is better... so the sooner you can ditch the f/1.4... the better.

I like to think that I know what goes on from the retail side of things with camera gear... and when the 35 art came out... I thought it would be a dagger for the 35L... but the 35L dipped in price a little and now it is back up to its all time high of $1479 US.  I know there will be rebates and the price will fluctuate... but I thought the 35 art would put some serious pressure on the 35L and I was wrong... ???

Even the resale value has held for the 35L... The resale for the 35 art hasn't plummeted... and it has remained around 780 +/-, but 1100 v. 780... a 300-400 difference for a lens that is supposed to outperform the more expensive one...

So I'm trying to apply what I learned about the above to the 50 art and the 50L.  But with the 35's... you can say the performance was comparable... so it was just another option available which is why the demand for either hasn't really changed much.  BUT the 50's are like night and day... which is why I am really curious about the art's bokeh.  If it can be described as magic... then that negates ALL of the 50L's claim to fame. 

As for the new Canon, it has to be in a different price range than the sigma 50... and that means they can still sell it at 499 and it will appeal to a different market than those looking to spend $1000 on a 50mm lens.

I look forward to your results.  I immediately eliminated the otus from consideration because of its pricetag... which is to say I can afford it... but it would have to be on my body 100% of the time to justify the cost.  And since I do a good deal of portraiture... ok... it would work... but the other good deal of my efforts are sports photography... and it wouldn't cause me to drop my 70-200 mkii in favor of it. 

But at $1000... I'm willing to not care about the percentages...

I had the 85 f/1.8 as my main portrait lens when my baby was born 7 months ago... the 3 ft minimum focusing distance is what annoyed me.  The lens was excellent wide open (maybe that is overstating it... it was very good)  but I kept bumping up against the MFD... and it wasn't as if she was filling the frame... so I'm glad I have my 100L again.  But that isn't really a walk around focal length... I think the 50 on a full frame... might just hit the spot and I can retire my 24-105 for those duties.

But the conclusion I've come to... is that Canon may cost more, but more often than not, it is well worth it. 

As long as Sigma has no choice but to reverse-engineer Canon's AF system, there always remain a chance that a Sigma lens may no longer work, or no longer work 100% (such as weird focus behavior in live view, etc, which I have experienced with some Sigma), with future Canon firmware updates or future Canon bodies in general. 

Having dealt with Sigma service before with headaches abound, I can understand those who stick with the Canon brand. 

In addition, unlike the Sigma 35 1.4 ART and Canon 35 1.4 situation, the 50 1.4 ART vs. Canon 50 1.2 L situation do not deal with the equivalent lens aperture class. I understand many here who will say the small stop of light advantage does not mean anything, especially since it's not sharp wide-open, etc, but the general public may feel differently in perception. 

Having said that, I will happily keep using my 50L for another year or so, as I do love the small size and rendition of 50L, then I will likely pick up a used 50 ART or on heavy sale in future.

Yes, and any future malfunctions of 3rd party lenses are most likely deliberately caused by Canon in hopes of forcing brand-loyalty. Sigma knows this, and is the reason they offer the USB dock. So when your lenses all of a sudden have issues, complain to the responsible party, not Sigma.

To summarise, if Canon want to come out with a killer 50/1.4 lens that will replace their current 50/1.4 (and maybe 50/1.8), it needs to be:
1) cost less than $949 so that it is cheaper than the Sigma 50/1.4 Art
2) deliver better quality images than the 50/1.2L
3) provide at least IS and possibly weather sealing

... wait, no it doesn't ... all that Canon's next 50/1.4 lens will need is this:

1) a red ring around the lens.

and people will buy it in preference to the Sigma, regardless of price or performance.

It also needs to autofocus consistently, something Sigma's 18-35mm f1.8 and older 50mm f1.4 can't claim to do.

Bokeh looks clinical, not as soft as the old 50mm f1.4. But clean... Kind of want this lens.

The F stoppers review of the 50mm ART rates it as having a much higher keeper rate than the slow focusing 50mm F/1.2 Canon L and as having excellent focusing. Keep in mind this isn't a review from an amateur, the guys who made this claim shoot every single day. That's a very good indication.

The older 50mm f/1.4 was junk with focusing, I have the new 18-35mm though and have had zero problems with focusing

BUT the 50's are like night and day... which is why I am really curious about the art's bokeh.  If it can be described as magic... then that negates ALL of the 50L's claim to fame. 

The 50 Art actually used the 50L as a benchmark for bokeh, and in technical terms the Sigma has better bokeh than the 50L. The Sigma's circle of confusion, which is what defines bokeh is actually much creamier and less busy then the Canon, with fewer aberrations, softer edges and better texture. The Sigma is closer to what is considered ideal like what you get with the Canon 85mm f/1.2 L II. 50mm planar design lenses like the 50L are hard to tune for ideal bokeh so Canon actually had to compromise with their 50L lens on bokeh and the lens has several flaws, the 85L II is very forgiving design wise so you get much closer to the ideal, with no compromise, and a very soft circle of confusion.

I think that for most photographers who are trained on what looks "ideal" the Sigma definitely should be considered to best the Canon, they are both very similar to one another though.

There are a few schools of thought on bokeh though, some people don't like bokeh that is too creamy because it looks clinical. A lot of photographer want bokeh to have a hint of character and definition, while still being very creamy.

I pray that this is true.  I was thinking earlier today that I don't love my 24-105 that much... and maybe I'll get this as my lone lens for anything wider than 70mm... but that was just me thinking.

I am considering pre-ordering the lens because I would like to take it with me on my upcoming vacation. That means I need to receive it on May 1 at the latest.

But what does "expected availability: April 29 2014" means?
1 - they will ship all orders on April 29
2 - they will start shipping on April 29 following the order of pre-orders
3 - we will all receive the lens on April 29

I jumped in line as well earlier this morning, but I'm still not sure I'll keep the pre-order or keep the lens once I get it.  While the 50L has some issues, I still love the lens and don't know if this lens will be a big improvement for my uses of the 50 prime.  I took another look at the imaging resource samples last night and while the bokeh looks nice, especially compared to many of the previous Sigmas, it's not as smooth as the 50 & 85L.  Now that's being pretty picky and looking at it at 100% magnification, so I'm not sure that's relevant for prints, but the bokeh is one of the main reasons I love the 50L. 

Edit: just found these samples on CNet (http://www.cnet.com/pictures/sigma-50mm-f14-photo-samples/3/) and this one shows some LoCA.  Definitely not APO like Otus, but still not horrendous.

Hmm well I guess it's not APO!  :o ;D :'( :-\ :o :o :o

oh well. So it really can't take on the Otus from a pure optical standpoint. I guess that explains the radically lower price a bit. It appears to be a lot farther away from being APO than I had guessed it would be.

OTOH, sounds like it will be way sharper and have much better contrast near wide open than any 50mm other than Otus (where it sounds like it will be same ballpark, maybe a touch better in some ways, touch worse in others), but with the LoCA it ain't an Otus, oh well. It does have AF as well, which is actually kind nice to have at this focal length and it does cost rather a lot less than the Otus.

I wouldn't actually compare it to the Otus optically any more, one is a ground-breaking ultra-fast APO lens and one is not. However, compared to all the not Oti,it seems like one is a ground-breakingly sharp to the edges on FF and with strong contrast from f/1.4 design and the rest are not and it looks like the Sigma is the one to rule those all those others and with ease.

Anyway, ignoring the Otus, sounds like it will be all that and by a long shot.  :D
Compared to the Otus I wouldn't say it matches up at all because of radically more LoCA and LaCA. But the Otus does lack AF, which is a big minus at this length and costs a ton more which is a pretty hideous minus for most. So the best 100% modern-day practical 50mm by a long shot.

are they getting misfocus at f/1.4? it looks a bit dreamy and soft like the canon 50 1.4 no?

CNET images are sharp, so I take it you're referring to popphoto? I do think that the shot of the tree was mis-focused, even stopped down it looks soft. But, did you check the other shots at full-res? Most 100% crops at f/1.4 (especially the first shot of the sunglasses) look way better than any Canon 50mm I've used. Anyway, I don't think popphoto set of images was "shot properly" for our scrutiny; a lot at ISO 1600 and unnecessarily overexposed.

I think if you look at samples from a wide variety of source, you'll see it's living up to the hype.
