Just a nitpick, but wouldn't a 24-70 f2 fall under their "CONTEMPORARY" line and not ART?

A 24-70/2 OS is the only one of these that would excite me.  The 18-35/1.8 seems to indicate Sigma could go this way.  As long as it were around 70-200/2.8 size or smaller, that would be fine.

If the Canon 24-70/2.8 had IS, I might have considered it.  But without IS, all of them are non-starters for me.  I'll just keep my 24-105 in that case, which is exactly what IvI've done.
You mean as they DID, all too often, not do. The AF issues with Sigma 35 and 50 are in line with any lens, including that of your precious Canon lenses.
Might be fine...if Sigma doesn't botch the reverse-engineering of the Canon AF system as they do all too often.

The 24-105L is a decent lens, actually quite good if you can shoot in the f/8-f/11 range, but not as good at apertures wider than f/5.6.  For me, a standard zoom is usually used for people or on a tripod, so IS is essentially useless...I'm quite happy with the stellar IQ of the 24-70/2.8L II.

hmmmmm...I rather like the sound of a 24-70mm f/2 DG ART....  :D

that sucker might be size of the 300 2.8 IS!  :o

They could make the 24-70 F2 with a little hook to the rear, that way when your arms fall off trying to shoot with it you can hang it on your light stand and use it as a sand bag.

Definitely Art, definitely not their lower spec / price Contemporary range.

I'm still unclear whether there is any substance in the 24-70mm f/2 rumour or whether it's based wholly on that photoshopped fake pic that did the rounds a while ago. Sigma considered 18-35mm the broadest zoom range they could do on a high quality f/1.8 AP-S lens. How realistic is it to suppose Sigma now has an optical formula promising similar quality in a full-frame f/2 2.9x wide-to-telephoto zoom?

My missing Art lens list is:
Sigma 12mm f/2.8 DG ART
Sigma 20mm f/1.8 DG ART
Sigma 24mm f/1.4 DG MACRO (1:3-ish) ART
Sigma 85mm f/1.4 DG ART
Sigma 135mm f/1.8 DG OS ART
Sigma 100-300 f/4 DG OS ART

+1 to all of the above. My picks would be 20mm f/1.8 and 135mm OS, only because they'd fill the gaps in my current prime collection.

Sigma's previous 100-300mm f/4 was, by most accounts, a superb lens, and much smaller, lighter and easier to handle than the 120-300 f/2.8. I'd love to see the 100-300mm f/4 given Sigma's Global Vision treatment.

The cost of new "white glass" is beyond most of us now.  Sigma has proven it can make a competing lens in the lower prime and zoom range.  Cost versus performance is the key to success here.  The market for under 200mm is flooded with options.  Sigma needs to go big and fast if they want to capture the market. Attacking the longer lens market makes good marketing sense.  A competing lens for Canon's 200-400 would be a smart move.  Quality has to be the #1 objective to break into this "deep pockets" territory.  Personally, I think they should not attempt going past 500mm at the top end due to f stop considerations.  I think that's why Canon stopped at 400mm.  If you can deal with the light loss of an extender, Canon's flip in 1.4x makes perfect sense.  If Sigma wants to deliver a knock-out punch, The perfect range would look more like 150-300mm f2.8-f4 with a flip in 2x converter resulting in a 300-600mm.
If Sigma could produce that lens at the quality/cost breakaway point, they would break into a huge market.

I don't like the IQ degradation with extenders. Yes they work ok, but you're far better off without.

I think the 200-400 and Sigma 300-600 are in different markets. One is sports shooter's dream, the other is a wildlife lens with added flexibility.
If they want to compete with the 200-400 they should make a 200-400. Of course what I really want from Sigma is a 600mm prime, but apparently zoom sells so I'll just have to suck it up (if the new Canon 800mm is over $15K I'm going to cry).

A 300-600 f/4 would be huge. An f/4.5 slightly smaller but might create problems when used with TC's, especially the 2X, i.e., 600-1200 f/9 wouldn't be usable with 1Dx AF while a 600-1200 f/8 would. A 300-600 f/5.6 wouldn't be usable at all with a 2X TC. The problems are even worse with camera bodies that only AF with lenses f/5.6 or faster.

So, at the risk of repeating myself yet again, why not a 200-500 f/2.8-4, that holds f/2.8 max aperture from 200mm to 350mm? And why not a 300-800 f/4-5.6 that holds f/4 from 300mm to 560mm?

The two I'm most hoping for are the 24mm f/1.4 and 135mm f/1.8/2 OS. The 85mm would be welcome but I have a Vivitar (Rokinon/Samyang) 85mm f/1.4 that I'm extremely happy with (which is strange, as its contrast is pretty bad and flare control non-existent, but I just love the aesthetic it gives; very filmic). I'd also love a 24-70 f/2, and I wouldn't care how heavy or big it is. However, I'd still be stoked if they put out a 24-70 f/2.8 OS offering, as I do video a lot.

Additionally, if any of you checked out sigma-rumors they also have this exciting lens listed:
  • 16-20mm f/2 DG Art - listed as "60%" likely.

I would LOVE a fast uwa zoom like that. I shoot concerts a lot from the pit and I need the fastest glass I can get. They did list other focal lengths as possible (16-24, 14-20) but with a f/2 constant aperture I imagine they'd have to keep the zoom range short. 16-24 would be ideal for me. Wouldn't have to get a 24mm f/1.4 in that case!

I am looking for some halfway affordable longer zoom for occasional birding/wildlife/airshow shooting. The Tamron 150-600 almost had me convinced, but at least on APS-C the long end seems to be bad enough that one should probably use it as an 150-500. That puts me off and the fact that it is on backorder everywhere in .de.  ::)
If Sigma had something in that range (200-600mm?) with better IQ at the long end than the Tamron while keeping the price at a reasonable level (<2000), I might be tempted. I wouldn't even mind f6.3 at the long end if wide-open performance was acceptable.

I was hoping for some primes to compete with Canon's 400/500/600mm primes.  A 300-600 would be interesting, but it likely won't be f/4 throughout; probably something like the Tamron instead as the weight would get too significant.  Ah well; I can still hope for something in the future.

I'm sure they are coming, although I doubt they will deisng a 400mm f2.8.
Their 500mm f4.5 is a well regarded lens and one which seriously do with an update. An IS unit, opening up to f4 and the ability to take teleconverters without Af issues and weather sealed should do the trick.

The current Sigma big primes are over-heavy, over-priced (£4799 for the 500 f/4.5 and £5499 for the 800/5.6) under-perform in MTF and lack IS. To compete with Canon they will have to improve hugely and keep the price really down. When you want the ultimate, a £1000 here or there in £5000-8000 is not usually a deal breaker. I would like an ultra-light very sharp 400, 500 or 600 f/5.6 at a competitive price and leave the f/2.8 and f/4 to Canon.
