It seems a bit unbelieveable but then again so did the 18-35 f/1.8 at the time.
That is for APS-C models so it has much less glass than it would have if it was an FF lens.

The first pic of this new lens has been posted on CW.  May very well be fake.

I think the new series of Sigma lens are amazing and they are so sharp it is scary!  However not sure if I was the only one experiencing this but after buying the Sigma 35mm 1.4 (their new one) I ended up returning it and taking the older Canon 35mm L 1.4 instead.  While the Canon is less sharp, I was always finding exposure to be weird with the sigma .  With the Canon 35mm however my exposure was always on the notch.

Anyone else experience "exposure" challenge with the new series of sigma lenses?
1DX, 24mm f1.4L II, 35mm f1.4L, 50mm f1.2L, 85mm f1.2L II, 135mm f2L, 24-70mm f2.8L II, 70-200mm f2.8L IS II :  D800, D4, and a whole bunch of Nikon lenses

Given that Sigma probably wants the price for this f/2 lens to come in under the Canon 24-70 f/2.8 ii, (and they might also want to keep the weight as low as they can)...it's possible that it will not have stabilization.

I think either way it has the promise of being a terrific lens.  Like others, I was planning on buying the Tamron at some point, but now it looks like there will be even more choices.

Q: The 28-70 mm f/2.8 class lenses have been superseded by 24-70 mm f/2.8 instruments. Taking into the account the success of the Sigma 18-35 mm are you already thinking about a full frame construction of that type or rather about e.g. a 28-70 mm f/2.0 or a 28-50 mm f/2.0 model?
A: We don’t have a very concrete idea at the moment, yet we will keep on considering designing large aperture zoom lenses.

not me...
sorry you had a bad experience...and your 35L is likely pretty good...however

me
I sold my 35L - actually in anticipation of a coming 35L II...I was not using it as much as I thought..maybe because wide open was not quite 'there'...liked it but was preparing for a coming Zeiss killer....

I did like to use the shorter 35L hood also on the 135L .........made a nice small kit...with just a little lens bag....and they shared filters too......but the CA and sharpness was one notch low...

but then ....Canon ran into the closet and shuddered...(it seems to me) ...with their current, unreleased - 35L II  at the appearance of the sigma 35 1.4...and its loved performance .....so I tried it...

it is a couple clicks off perfect (MAed to my 5D3)...and sharper wideopen than the canon was at f2 or f2.8
solid exposure, colors...very low CA/fringing....almost as fast to focus if not the same...and accurate
(I give credit to the 5D3 there)
if Canon puts OUT their revamped-but-struggling 35L II-b, then I will try it....
of course it will be $2000 or so....ha!

also canon better get busy replacing the 180mm macro with a f2.8 I.S. or maybe f4 I.S ...or I will just relent and dive into Sigma again...

well,
while I am on the subject...the 24-70 f2 rumor (with or without I.S.) may also take some of my money...

/////////
I am glad your 35L pleases you ......mine did not - fully ..... to answer your question

I love Canon but they need to get their board and engineers awakened... 
just how I see it

I recommend the sigma 35 ..... maybe try another one

I second that. Canon should get the engineering staff to start again working on great ideas. Normally 3rd Party Manufacturers should *see up* to the L-Line or Canons homebrewstuff, but at the moment we can just pray that new lenses will match the latest ones from Sigma. How's that coming?

However, we shouldn't forget that there are some points missing on the Sigma 35mm. The lense is not weathersealed which will keep it out for professional outdoor-use. The old Canon 35L isn't either, but the new one could be sealed. The Sigma is even a really heavy one, which is not the best spec for streetphotographie, so maybe the Canon 35 f2 IS is far more usefull if you don't need the Extra-Stop of light. In fact, on FF the DOF is quite good with f2, too... and I never heard anyone complaining about the qualities of the 35mm f2 IS.

Which leads us to the Sigma 24-70 f2 OS... I would love to see the results and I'm considering to buy it for a reasonable price, but I don't think it will be too much spread on professional photographs if it's not sealed, again.

I second that. Canon should get the engineering staff to start again working on great ideas.

It seems to me it's not about ideas, but about laws of physics - the innovative 200-400L is heavy for a reason, the same reason why they left IS out of the 24-70L2. And they are innovative with IS primes and hybrid af on the 24-70/4, while your request for just "updating" the traditional 35L with better iq contradicts the great ideas you seem to want.

One real innovation though will be the new line of DO lenses, there have been lots of patents on CR, but who knows when these will be released - probably only when they sold a non-DO prime to everyone so people have a reason to upgrade :-p

If Canon released a new line of DO lenses, I bet you would see a lot of people in forums like this, complaining that they don't have enough contrast...and wishing they would make a counterpart that did not use diffractive optics.  There's no shortage of people who like to complain.

More than 10 years have passed since the Canon introduced a DO lens. They should be able to make DO lenses with enough contrast by now...  ;D

Just wondering, how often do you (the readers) shot at 2.8 and want something faster?

...This will be a large 24-70 lens... Unless the IQ is significantly better than Canon's at mid apertures, I will skip this lens.

Yes, I shoot faster than f/2.8 (f/1.4-2.0) ALL THE TIME. So if this lens is real, I WANT IT:
1. I'm tired of swapping primes, and my 14 f/2.8, 35 f/1.4, 85 f/1.4 aren't enough, need 24mm too, OR... a 24-70 zoom.
2. I hate flash photography, and for available light indoor or night photography, I need a fast lens AND OS.
3. I'd GLADLY give up a stop of aperture (vs. f/1.4 primes) for 3-4 stops of OS; I was going to give up 2 stops with the Tamron 24-70. Zoom + OS = slam dunk. If the Sigma doesn't have OS, I will probably opt for the Tamron for the VC.

Many mention weight concerns. But if I can carry one 40 oz lens (1.1 kg) instead of 70 oz of primes (21, 23, 26 oz for 24, 35, 85mm f/1.4 primes), save minutes of lens swapping, and avoid missed shots swapping lenses, I'd do it in a heartbeat.

Or maybe DO was the wrong way. Physics don't change, even after 10 years ;)

They should also be able to make 1.6x sensors at least on par with those found in Nikon, but apparently they can't.

I did but not with the new ones - with the Sigma 15 (produced last year). The exposure was at least one stop brighter and inconsistent with my 5D2. I always thought that this was some oddity of the fisheye design that Canon knew how to deal with but Sigma did not.
