70mm is not that useful. There's a reason why you don't have a 70mm prime lens. It's close to the portrait range but not quite there.

I totally agree on the weight issue. But I'm highly skeptical of the idea that 85mm is infinitely more useful or practical than 70mm. It may be that people have unwittingly gravitated toward a convention. But I can't imagine there is anything inherently better about 50mm or 85mm, except that they are evenly spaced from other lenses in a lineup, and photographers have based their shooting around these ultimately arbitrary lengths.

85mm instead of just 70mm makes not a big difference, but enough, to me, to make sense. At 85mm you have that little bit shallower dof and that little extra reach (along with a "flatter" perspective) that can come in handy in a walkaround lens. That's actually what I miss most using my 24-70/2,8.
A 24-50mm, in my opinion, wouldn't be much popular, unless it is very fast and has an outstanding IQ. I once had a Pentax 24-50/4, but I always preferred to carry around three primes, which were much faster and had a much better IQ, since I had anyway to switch lens quite often, with such a small focal range zoom.

Erm... Bring the 70-200 f/2 too and damn I'll buy those two preciousssssssssssssssssssssssssssssssss
Doable, I guess, big and heavy for sure, and a filter size of 105mm+. Similar to size/weight of 120-300mm f/2.8 or 200-400mm f/4. Betting now the price will not be less than Canon 70-200mm II if it ever materializes.

Less than the 70-200/2.8?  The 200/2 is $5k+ so a 70-200/2 would be more costly and very heavy.
Sorry, I should have been more clear, I know what I said was a huge understatement. I was trying to show that if this lens ends up becoming a reality, AND costs less than the Canon 2.8 lens it will be awesome, but the idea that an equivalent telephoto f/2 lens for the same relatively bargain price does not seem feasible.

I think Sigma has hired a witch.  I think witchcraft is the only explanation for being able to bend light this well.

witches the illuminati and probably some reptilians are behind this.

24-70mm 2.8 lenses are already huge as it is. A 24-70mm 2.0 would be stupid big for a general all-purpose lens.

To be fair that's pretty much what they've come up with for ASPC users, a 28-55mm lens with excellent image quality wide open.

What I would question though is whether the appeal on FF would be as great, for one thing I'd say this range is better catered for with primes already and for another f/2 on FF is going to be a shallower DOF than f/1.8 on ASPC for the equivalent angle of view. Personally speaking I'd be interested in such a lens as I like to take landscape shots with shallow DOF but I think something like a 35-70mm f/2 might have a wider audience.

"Feasibility" in this case is relative to supply/production cost (no one knows for sure) but also demand, and looking at all the drooling CR members in this thread Sigma would be Nikon-crazy to sell something unique like this for anything less than $3000 if the iq & af is really good.

APS-C users are for sure more willing to buy such a short range zoom, to get a more "FF style" look in terms of dof. FF users... whole different story. What's more, a zoom like that for a FF, to have a good IQ, would still have to be quite big and expensive, I guess that few people would prefer it over a 24-70/2,8. Definetely, not people who are looking for a walkaround lens. Even people who shoot landscapes would probably prefer a 16-35/2,8...

I'd kill for a (very) fast 35-85. Much better than 24-50 imho as 35 can already do pretty good lanscape but 50 is out of the butter zone for portraits.

The size mostly depends on the longer focal range, so a 24-70 would be smaller than a 35-85, I guess. I'm still not convinced that a 24-70 f2 would be too big. A 35mm aperture-caliber is nothing impossible... a simple 50 f1.4 has a bigger apperture. Maybe the OS/IS would make some differences and that could be the reason why canon choosed to make a 24-70LII without IS.

I think Sigma could make it without getting bigger than the current 24-70II, new patents and engineers arrived... and everything seemed impossible until someone actually made it.

18-35 f1.8? No way... no one can make this! ;)

It will be heavy, It will be big but at that point who cares? F/2.8 lenses are already heavy enough, might as well make them F/2.
