How does MTF compare to Canon 24-70 2.8 II ?

hard to say as Sigma use a proprietary tech to produce their MTFs. it would not be fair, apples to apples, comparison.
our best shot at this stage is The Digital Picture and/or Lensrental reviews. Lenstip also tends to get their reviews early on but I would see what The Digital Picture had to say first.

Question: Has the new Sigma hypersonic AF motor with 1.3x more torque features in the new 85mm Art shown us the AF issues reported by some users was not software incompatibility but simple underpowered hardware all along?

Will this lens with that new HSM motor be a good focused?

Alex_M was banned from the forum for offering a "personalised, in person entertainment session" to a forum member that for some strange reason kept insulting him on forum pages. Alex_M asked that forum member very politely to remove the insulting posts from the forum and that was also reported to forum admin. What happened is that, Admin has banned Alex_M from the forum for posting "threatening message". Nice and easy :)
Apparently, this is how it is. Alex_M sent a message to forum admin and asked to reconsider his decision. No response received so far.

Hope Admin will reinstate you. Alex_M was a nice guy! :)

time for Canon to add IS to the 24-70mm f/2,8L III?
::)

yes. it will just be called EF 24-70/2.8 L IS ... not "III" ... and yes, by all means, Canon should have added IS already when they launched the current version "II". *stupid* Canon.

let's see how good the new Sigma really is ... and pricing ... and when it will become available ... remember the delays with sigma 24-105/4 Art? ,-)

opps. My bad.
Maybe Canon should look into In-Body-Image-Stabilisation... Like Sony, Olympus, etc etc....

also YES! But not for DSLRs - too late, no point any longer. But for a mirrorless FF system Canon should include in-body stabilization. ;) 8)

Actually maybe Canon did not had the adequate tech or the IS f2.8 mechanism was flawed and they needed time to perfect it.

not possible! Canon is innovative, capable and perfect! :P ;D
Or it could be that they can pretty much sell the lens range multiple times.

Looks good. A stabilized 2.8 24-70 with a zoom ring that turns the right way.

Maybe the next gap for Sigma to fill: 16-35 2.8 OS, so stabilized, accepts filters, less massive than Tamron's 15-30 2.8 VC and also (unlike their 12-24 and Tamron's 15-30), turns the Canon way.
