The miserable onion bokeh on the portrait shot was all I needed to see to wait for the Canon II instead. Though the 24-105L serves me very well and has IS...

That being said, the guy who reviewed the Tamron in the review you are referring to, says in the comments-section that the onion bokeh was due to water droplets on the front element as it was raining. I’d wait to see some more tests before I write it off.

Any news on the "onion bokeh"? The LenRentals review didn't change, and I just saw that the Sigma 50/1.4 suffers from it (, too?): http://mansurovs.com/nikon-50mm-f1-8g-review ... Does anyone have the Sigma and feel that it's bokeh is bad due to this effect?

Check this thread.  Many people posted Tamron 24-70mm samples here.  Looks the lens do have onion bokeh effect.  The poster say that's okay.  However, I will just wait for more information.

This lens might change your mind.  In many forums people love this lens and are selling their Canon 24-70mm MK1.  I actually are waiting for three things.
1. The price drop.  The price of third party lenses usually drops in 6 months after they are released.
2. Self improvement.  All first shipment of new products are not perfect.  In few month they will have new internal reversion.
3. More reviews.  This will be the key to make me switch to this lens from my MK1.

Me too :-) ... but:

1. Is this really likely to happen given the demand? The 24-70ii is so much more expensive and hasn't got IS I doubt there will be the usual drop. And the 24-70i brick doesn't work well on crop and thus doesn't qualify as a "stepping up lens" for me.

2. There might be more production variance in the first samples, but are there really usually new "revisions" like in cpu designs? Looking at the current reviews, apart from the "onion" bokeh that is due to the design there doesn't seem to be any shortcomings.

3. More reviews won't tell me how much the "onion" bokeh affects my pictures, I guess I'll have to try it myself.

Although this lens won't affect the new MKII, it could throw a wrench in the used MKI market.
I only have a very old Sigma 24-70 that I almost never use so that might get me to update to a MKI. It doesn't make sense in my case to spend too much on a lens that I'd still use only rarely, so a bottoming out of the MKI market will work nicely.

I had a Tamron. I sold my Tamron. Would take a lot of great reviews for me to go back to a Tamron.
+1 I'm in the same boat once bitten twice shy, I am looking forward to seeing how the 24-70L II is going to perform

For me this comparison shows that the Tamron 24-70mm does not even come close to the MK I not even speaking about the MKII if it can deliver what the MTFs show ...

I'm pretty sure he got a bad Tamron sample and will re-test (he got another 70-300L for the same reason) because the iso chart shots contradict everything else said/written about this lens. The sharpness falloff should not be that bad.

But I really hope people will stomp the Tamron into the ground, because then it'll drop in price faster than usual and I can get one :-) ... the only drawbacks to me are really the "onion" bokeh and that its no Canon lens (ie. no cps).

Tamron gives you 6 years warranty and you can return it in 30 days if you purchase it from Amazon.  What I don't understand is why people don't return the lens if they get a bad copy.  By the way, Do you really think Canon 24-70mm Mark I is better than Tamron?  I believe many people get a bad copy of Canon 24-70mm L.

I returned the tamron lens i had after 2 days

I have never been really happy with the canon 24-70 mk1 so i dont own one as when i have tested it I wasnt impressed (I know lots of owners are happy though) I would say the mk1 has a stellar track record in this regard. so currelty I use the 16-35 or the 24-105 or primes dependign what i am doing
I am lokoing forward to testing the canon 24-70 mk2 though to see how it stacks up :)
I would be pretty happy if sigma released an IS one with the same build and quality of their 85 1.4 which I love

We'll see. It did better on the LensRentals tests and on a test some european magazine carried out.
For whatever reason, my results often don't match TDP and he seems to often have Tamron stuff test out poorly, for whatever reason.

I've never tried a Tamron lens but I've had sigma and my overall impression is bad. AF-motors froze, AF is slow and extremely noisy, no constant manual focus, poorly built and they do not last and they freak out in moist conditions. The only Canon lens I've had break was a 50 1.8. I have a working 16-35 2.8 from 2001  and a working 70-200 2.8 from 1996-ish, they do tend to last, at least the old ones did, the newer I'm not so sure, the overall build quality seems more flimsy and they have too much plastic on them.

The main reason I want this lens is for f/2.8 with stabilization. I WISH Canon had something like this. Either I loose the 2.8 or I loose the IS with a Canon product. If Tamron can do this with the IQ of the Canon 24-70 f/2.8 at a price that is $300 cheaper, it is tough to say no. I'm looking for a lens that stays on my camera 80% of the time. My 70-200 f/2.8 IS II is the best lens I own but it is really heavy, large, and too long for indoors. But I love shooting at 2.8 and the IS is great to have for stills and just about mandatory for handheld video. I'm sure most of us wouldn't even be talking about this lens if Canon offered one. Even if it was $2000
