From my short usage would say it is very well build and is very sharp in the centre and improved when stop down. Color is also well saturated and balanced. The best feature is the VC which really helped when I take short footage and long exposure handheld. From my non scientific testing, its sharpenss seems to match canon 50mm f1.4 @ f2.8. Make a guess which is which.
1st shot Canon 50, 2nd shot Tamron 24-70.

Hmm...got it wrong...lol
Am also interested to get this, but after some searching, there seems to be some issues with initial batches:
1) VC degrading IQ at high shutter speeds - apparently it's due to the delayed reaction of the VC mechanism kicking in (and it gets pronounced at high shutter speeds)
2) Miscalibrated aperture levers (this impacts the Nikon variant) - aperture is off by up to 1 stop.
The link is here if anyone's interested to read. Hope they can manage to fix these up.

I would say performance is pretty good for the price. It's a little bit soft at 2.8 but IMHO still acceptable. When stopped down to f/4, sharpness is improved a fair bit.
Did a quick shot the other day using my usual centre point focus. Did not focus and recompose though. Sorry for the mess. Focus was on the corner where the silver piping of the pouch is.
100% crop, no PP was done.
Pros:
- Good price
- Pretty good IQ (IMHO)
- Vibration Compensation (IS/VR)
- Pretty decent AF speed
- Some moisture sealing at the lens mount
- 5 year warranty
Cons:
- 82mm filter
- When you remove rear lens cap and look into rear element, the circuitry is exposed when zoom in (not an issue if you have lens mounted to camera body of course, just need to take care when changing lens)
- Zoom ring quite stiff but should get better over time.
- Heavy but not as bad as the Canon 24-70 mk1

Hey thanks for this.
Looks like the lens has good isolation capability and decent bokeh.
I'm just waiting for the Canon mk2 to come out and compare before deciding, but given that I have many primes covering this range, I'm not sure if I really need this zoom range.

Thanks for sharing. I think you really thought it out well before buying.
