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.
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.
