Judging by this:

Sample variation at work above, but on sample 2 its slightly better on the Canon front.

Not much between them is there?

What are you talking about? The Canon looks much better than the Tamron in everything except the 70mm center frame, and it looks much better on corners period. The difference in the center is negligible. Detail will be far better on the Canon it looks like.

You're probably right, I was focusing on the centre. The Canon does still look great though. At f2.8 it rivals the 35L and the 24L at respective focal lengths.

There are few third party lenses (Zeiss and Leica R not included) that can match the corner sharpness of many Canon L lenses. The strange thing is that at 70mm even the version one looks to be sharper while being very slightly worse at 24mm. If that really is the case then I don't see the reason to upgrade at all.

Corner sharpness is again far better. Looking at test charts isn't the way to really evaluate the lens.

I don't have to look at the images to know that if I'm shooting at the extremes of shutter speed, the Tamron will be consistently sharper.

IS/OS/VS or whatever the company decides to call it is HUGE in the real world.

Judging by that website. the 70-200 mkii kicks both thier butts at 70mm 2,8. I think Canon could have done better TBH with this new lens. It's certainly not a prime killer like I was hoping.

Interesting because at lensrentals Roger's tests shows the 24-70II was better in the center and across the frame at 70mm than the 70-200II and the resolutions he was getting certainly put it in 'prime killer' category.

We're going to have to be patient and wait for the lens sample archive for the 24-70ii to pick up, 'cos at the moment that thread is looking pretty disappointing. Time will tell, I hope it does turn out to be a beauty.

IS/OS/VS or whatever the company decides to call it is HUGE in the real world.

ditto, my keeper rate compared to my 50L stopped down is a lot higher. I have no doubt that the mk2 exceeds the tamron when it comes to test charts or tripod shots, but I hardly use a tripod, so real world keeper rates would be significantly higher.

Anything close to 1/(2*FL) and the IS/VC/OS plays a significant role. When shooting with a non stabilized lens, my behavior changes a lot to cancel out basic motion blur. That results in light loss in some cases, and a full stop or two can definitely play a large role in the final output.

I am certain that a 24-70 IS L will come out, but tired of waiting for that mythical unicorn.

Go to the second copy of the 24-70 II and compare. Better at every FL and aperture.

I did find it weird when playing with these tests, that f/2.8 was sharper than f/4 on the sample lens sample and FL. At 35mm with copy II... Look here:

the first link shows that there is some backfocus on the new canon 24-70 at 24mm, and compared to 70mm, the canon 24-70 mk ii is correctly in focus. That is what my eye tells me.
