Can't really do such comparisons.... we don't even know if the MTF are real or computer-generated.
From everything I've read, Zeiss, Hasselblad, (and maybe Leica and the other MF mfgs) are the only ones that use "real" MTF charts.

I'll be excited about this lens if it's as big a bargain as the 18-35 - i.e. less than the white box BigValueInc, etc. price of the Canon 24-105.

Sigma is notorious for missing their target dates. Take that however you want. Some might say it's an indicator of poor planning, others might say they don't want to release a lens until it's ready. You decide.

On the Sigma homepage I can't find anything about "weather sealing"... this sucks -.- .... would be a nice travel/bad weather zoom lens!!  :-\

Hiding  ;D.   :-[

Guess Sigma are going to bring the ubiquitous 24-105 to Nikon and Sony.

I presume they must be aiming at 24-70 f2.8 II image quality at a price below the 24-70 f4 IS. I don't see how they can match discounted EF 24-105's price let alone the used ones which are out there in their thousands.

The 24-70 f4 IS is a very different lens it would seem. Small and handy, goes well on an ungripped body whereas the Sigma looks like it's a beast.

That will depend on Canon's game plan. Is the 24-70IS a replacement for the 24-105, or just an additional lens choice? I would expect the Sigma to trounce the 24-105, and handily beat the 24-70 f/4. I doubt it will approach the 24-70II. They will pick that fight with their own 2.8 (or lower) offering. This Sigma will likely be the best single lens solution for folks that don't have the cash or incentive to buy the Tamron or the Canon 24-70 2.8. Naturally, until we see the price, this is all speculation. I would expect it to come in at around $900-1000, but who knows?

how do these charts compare to canon charts?

 my question exactly.   I'm really curious if this lens will warrant  paying more than 650  for the Canon version.
Upgrade  path.->means the former was sold for the latter.

XS->60D->5d Mkiii:18-55->24-105L:75-300->55-250->70-300->70-200 f4L USM->70-200 f/2.8L USM->70-200 f/2.8L IS Mkii:50 f/1.8->50 f/1.4->100L->85mm f/1.8 USM-> 8mm ->100L & 85L

Why is Sigma so opposed to adding weather sealing? This could be a top lens if it had weather sealing. Same goes for their other recent lenses.

if it handily beat the 24-70 f/4 IS it would absolutely approach the 24-70 II!

They will be lucky to manage to tie the 24-70 f/4 IS.

They absolutely need to beat the 24-105 IS, we will see, the MTF look unpromising, but I'm not too familiar with how sigma MTF play out in the real world.

Interesting, the link now gives a "Not Found" error message. I think Sigma would make waves with this if it was $600, but I may be dreaming.

This does not mean that the image is not 3D rendering, done by Sigma.

I'm more interested in the previously rumored 24-70/2 OS.  If it's at least smaller and cheaper than the 70-200/2.8L ISII then I'd consider getting rid of the 24-105.
