Anyone seen any reviews of this lens???? The only reason I am looking into it...( I own no Tamron products)...is because of the delay of the CAnon 24-70 f/2.8 II.....(which, truly I know I will wait for...LOL!)...but I just wanted to see what reviewers thought of the Tamron lens...I am guessing the usual caveats....I doubt it will give the new Canon a run for it's money in the IQ dept., which is all that really matters to me.
 
Looking at the pictures, it appears that, yet again, Tamron didn't bother to make the focus and zoom rings turn the correct direction. Do they not realize that the primary customer for this lens is going to be a professional who owns lenses such as the 70-200L and 17-40L?

This is a serious usability flaw, and a dealbreaker for me. A consistent user interface is critical, and Tamron has broken it here. They finally graduated to the late 20th century and added USM and IS to their lenses; would it kill them to make Canon-mount lenses that behave like Canon's own lenses?

The backwards zoom was an instant deal breaker for me too. At least Sigma are a bit better, they do get it right on some but not all lenses. Puts me off the 8-16 though that I'd now rather get the Canon fisheye zoom instead of it.

Anyway, I can kinda see Tamron's view though. Bear in mind they're part owned by Sony who also turn the other way. That is by default their standard, and Nikon users wouldn't complain either. Guess they're not big enough to consider designing the two versions of mechanics to allow it to go the right way for the system.

I own and use lenses from all three vendors (Canon, Sigma, Tamron) and usually turn the wrong way once before I remember that I switched lenses - I guess I don't see it as that big of a deal.

Personally I cannot wait for this lens - I am so hopeful that the reviews are good because if they are my 24-105 f/4L is going up for sale so I can pick up this lens.

Who cares as long as it has stunning image quality? This is going to be Tamron's biggest issue by far. Every single one of their lenses, except for the 18-270mm & 60mm Macro, has performance that matches Canon lenses from the late 80's to early 90's for a price that's usually not much lower than the current ones. Some of their lenses besides the 18-270mm and 60mm are decent, yes BUT so were Canon's equivalent lenses from the 80's. Their lenses perform decently on paper but if you look at any comparisons on the-digital-picture.com they have extreme issues with hazing and soft corners, often to the point of being comically terrible.

The focus and zoom rings could be made of paper mache if the image quality is decent and it would still be a major acheivement as a lens and a major acheivement for Tamron. We'll have to see.

WOW! Thanks ...I love this site...I did not know that ...definite no for me right there.... I have an MFT lens that zooms backwards .... it so puts me off...the lens is sooo small and light with long reach that I decided to keep it...
but I agree with you...I am not including a backwards zoom in my FF kit....NO WAY!!!!!

No no no.

Canons zoom in the wrong direction. Nikons and Tamrons zoom correctly.

And yes you British and Aussies and Japanese drive on the wrong side of the road ;)

......but...but....YOU can't say that on a Canon Rumors Blog Site....?????????? LOL!
Maybe if you are in the Southern Hemisphere Nikons and Tamrons Zoom in the PROPER direction!?!?
...but I think the IQ is not that great in either hemisphere! :-X

Does anyone know if MTF charts are available for this lens yet?

I like the price and the VC but it will have to be sharper in the corners with less distortion than the 24-70L I to attract many/ if-any canon users.

Comparing the MTF charts from the Tamron to the 24-70L I it looks like the Canon is going to have better sharpness. And for nearly the same price, I'd take the robustness of the Canon over the IS and future compatibility issues of the Tamron.

One area where this lens is sure to shine is in terms of bokeh. To my eye the meridonial and sagital lines are extremely close together across focal lengths and from center to edge. Looks like in terms of sharpness it loses out handily to the Canon L v2, but it beats it in terms of bokeh.

It does have nine blades. You might not be able to see the contents of your model's every pore edge to edge, but it should make for some fairly pleasing portraits.

You forgot the Tamron 17-50/2.8 non-VC version that optically perform comparably to the EF-S 17-55/2.8 USM IS (i.e. excellent) for a fraction of the price.

That's not a very encouraging MTF chart.

Whaaat? I don't know how you read the MTF charts, but looking at the ones provided by dilbert (thanks), wide open the Tamron will generally be similar or superior to be mark I (in particular in the corners and at 70mm). The bokeh is also poised to be great (as smirkypants pointed out), but we will have to wait for actual samples to be definitive.

If there are no AF issues, with VC I'd say we have a clear winner here (compared to the mark I). Compared to the mark II the story is different, but I could still see the Tamron be attractive, not the least because of the price and the VC. If build quality or the zoom/focus ring directions are of critical importance, then no, the Canon will clearly be the lens for you.

Especially compared to the II from Canon... Though some people have been clamouring for IS... Though not sure is IS is all that great if the image is soft to begin with. I would prefer tack sharp with some misses than a peak of muddied across the board
