Roger at LensRentals impression of 24-70 II

To me the numbers make a strong argument for the Tamron. People have sworn by the Canon 24-70 Mk I, yet the Tamron beats it in resolution and adds IS.
I don't own a 24-70, but am looking for a faster alternative to my 24-105. Hmm... My concerns would be AF speed and build quality.

I'm afraid that Tamron's glass glue isn't going to cut it in many photographers' work environments —bchernicoff said:

And the original Canon 24-70 was sometimes a lens to swear at rather than swear by —

Much better than I expected. I guess I'll have to finally bite the bullet. After five poor mark one lenses, there is finally one worth having.
The Tamron breaking down so early in its life does not bode well for being able to count on it when needed. using three dabs of glue to hold a large diameter element in place is really cutting corners. I'd expect them to be failing in droves before they are a year old, and as the adhesive dries out a little more.

Worse distortion at 24? 
The new Hood design makes it non-working at 70mm, bumps go straight to the barrel when extended.
Strange to me...
Equally strange is that it outresolves the ts24, that makes no sense in a great way!!
I'm very happy for those needing a 24-70 it's by far the best standard zoom ever. For me it must have been made differently to appeal..

I certainly hope so, but so far, they have been silent. They don't have a good record of acting quickly to such issues. Those who use the lens in temperature extremes where expansion / contraction is prevelant might be affected the most.bchernicoff said:

I believe they will. However, how soon? 6 months or 1 year? The good thing is Tamron give 6 year warranty. For normal users, they shouldn't worry about the glue issue. If the glue is not strong enough, the glass should fall down in 6 year. Tamron will repair that and you also can ask Tamron do adjustment for your lens at the same time.
However, for PROs you cannot afford two weeks without a 24-70mm lens because that's your tools to make money.
I believe Tamron is good enough for non-PRO, and a PRO should get Canon 24-70mm MK2. My 2 cents.

Yeah, the difference isn't much, but the old one wasn't very good in this respect, so worse is quite bad distortion.
