Canon 24-105 f/4 L IS vs. Tamron 24-70 f/2.8 IS vs. Canon 24-70 f/2.8 L II

I bought 2 Tamrons a few years ago...

Never again... for me once shame on you, fool me twice shame on me, fool me three times I totally deserve it!!!

yeah once was enough for me I wasn't going back for seconds of that dish!

I had the Tamron rented 2 weeks ago. Liked it, the vignetting was a little strong IMO at 2.8 though.
It took sharp images, but my copy appeared to have the 6D issue with VC. Apparently the newer Tamron 24-70 VC's function perfectly with the 6D.

I receive the Canon 24-70 f/4 IS tomorrow night for a week long trial as well. I will report my results here.

I had the 24-105mm before, but the Tamron blew it away if you don't need those last 35mm.

I own both the 24-105 and 24-70II
I bought the 24-70II even though i own the 24-105 for 1 reason, sharpness at f2.8. That's also a big reason why many other buy this lens isn't it?
Depending on what you shoot, for me, it's 90% portraits, 10% events and for both, i don't need IS.
What i need is a sharp lens.
If possible, most times i'll use my primes but there are situations where a good zoom is essential and this is where the 24-70II really shines..it's almost as sharp as my primes for portraitures..

+1 I ended up selling my 24-105. Not nearly as sharp. The extra stop of light comes in handy too.
