How does MTF compare to Canon 24-70 2.8 II ?
alex_m_is_back said: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.

alex_m_is_back said: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.

AvTvM said: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....

Actually maybe Canon did not had the adequate tech or the IS f2.8 mechanism was flawed and they needed time to perfect it.AvTvM said:... and yes, by all means, Canon should have added IS already when they launched the current version "II". *stupid* Canon.

Or it could be that they can pretty much sell the lens range multiple times.AvTvM said:Diko said:Actually maybe Canon did not had the adequate tech or the IS f2.8 mechanism was flawed and they needed time to perfect it.AvTvM said:... and yes, by all means, Canon should have added IS already when they launched the current version "II". *stupid* Canon.
