The September release date for the Tamron indicates to me that marketing wanted to get their oar in the water along with the new Sigma before buy decisions were made. Perhaps now, a new Canon with IS will be leaked to the rumor mill.

I'm a big fan of Tamron and this new line of lenses. I owned two of their original 24-70 and a couple of the new series. So I'm pretty disappointed that the optical design wasn't improved. Yes, there may be some better performance created via coatings, better tolerances, etc., but I suspect this won't cut it when compared to the Sigma offering.

Keeping an open mind, but my expectations are lower now. (Especially relative to the price)

I won the current Tamron 24-70 2.8 VC for Canon and have been quite happy with it on my 6D, and I frequently use it with VC handheld and like the results. 

It does have one issue which drives me batty -- if I am shooting it on my tripod and forget to turn the VC switch off, it *destroys* the image.  I forget to switch off IS once in a while with my Canon lenses, but the quality impact on the final image is minimal to unnoticeable with those lenses.  The Tammy, however, will produce unusably blurred results -- it REALLY moves that VC system when you trigger the shutter if you have it on a tripod.   

Of course, that is pure user error, and I have gotten better about remembering mainly because of the Tamron, but it cost me a few big disappointments in fleeting light that, by the time I realized my mistake, I could not re-shoot.

Hopefully the new generation of the VC will refine that behavior out.

Same optical formula but that doesn't mean same performance. The first version was very sharp if you got lucky with a well aligned one.

I must have been one of the lucky ones, my 24-70 G1 is very sharp across the range.

That's the same with all IS systems, though. It just becomes more apparent when the IS is effectively-implemented, as IS which is capable of correcting stronger motion will result in even more blur and alignment issues when on a tripod.

As we move forward IS is going to be more and more standard for all lenses, so it's a good idea to get into the habit of always turning IS off when using a tripod or when mounting/unmounting the lens, no matter what brand it is.

So only 4 lenses left for tamron to upgrade 2 of which are macros. Eagerly waiting for the update to both those macros before 15-30mm and 17-50mm lenses.

I don't disagree that that switching the IS off while on a stationary mount is absolutely a necessary habit, and I regard not doing so as completely my error, but I will say that the Tamron, at least my copy, is in a class all by itself.  I have a Canon 70-200 IS 2.8L Mk II, a Canon 100-400 IS L Mk II, and a Canon 100 IS 2.8L Macro, (and back in my 7D days, a Canon 17-55 Canon IS) and I have been able to get away with very good results with all of those lenses even when forgetting to disable the IS.  My workflow is usually  ... mount the camera/lens on the tripod, manually set focus using Liveview 10X, then take a few frames for histogram exposure adjustments.  Then I remember to turn off IS if I am lucky before I take my final shots.  If  I forget with my Canons, I still get pretty nice usable results, sometimes very, very slightly blurred, and sometimes indistinguishable from after I switch the IS off.   This allowed me to form my bad habit.  But once I got the Tamron, I always get fantastically blurred results -- they are simply not usable at any size.   In fact, if I activate the shutter using a remote release on the Tamron while watching the LCD in Liveview, you see that that the lens engages in a single small but noticeable movement, seemingly always from the lower left to the upper right, and then stops.   I tried this with my Canon lenses and no movement is apparent.

Now I love the IS on all of my lenses so equipped when I am *not* shooting on a tripod; it was my reason for buying the Tamron over the Canon (I didn't win the Tamron -- that was a typo, I meant to type that I "own" the Tamron).  I don't find that the Tamron is in another world IS performance-wise; all of my lenses work quite well there.  But the Tamron does stand alone for blur on the tripod.

I used to get a massive amount of blur shooting with the Tamron 24-70 F2.8 VC handheld and VC activated at shutter speeds faster than 1/70s.
Therefore each time my shutter speed crossed into faster than 1/70s territory, I had to flick the VC switch off. Major inconvenience as in many situations shooting in Av mode I was getting poor keepers rate due to lens VC misbehaviour.
I spoke with Tamron support so many times and was advised that this issue cannot be fixed.
Onion ring bokeh was an another reason why I parted my ways with Tamron products for good.
My Canon 24-70 F2.8 L II serves me well in run and gun situations for now until the final judgement is in for the new Sigma 24-70 Art lens.

I don't buy Tamron for one reason - they permanently disable OS in their lenses for Sony A-mount which I was shooting ~5 years ago. I was so pissed when I got an A7r and wasn't able to comfortably shoot my 70-200 (via an adapter) because of this stupid decision. They also charge full price for the crippled A-mount lenses as for EF and Nikon which have OS. Old story, not relevant anymore, but still... :)

Interesting - Petapixel claims the onion bokeh is gone. No example shots that would show it though...

Sigma vs Canon vs Tamron 24-70mm...

Maybe Canon gonna introduce a mark III with IS
or
Canon gonna produce Sensor Stabilisation (SS?) for all future bodies.

SS + IS like in the case of Olympus?  ::)

The Petapixel review is impressive and my guess is that some shooters will go for this (over Canon) not only on price but on Vibration Compensation, which Canon surprisingly lacks. I am tempted myself as I sometimes miss not having f2.8 in my 24-70 (I have the f4L). However I love the sharpness of my f4L and the macro switch is unbelievably handy.
