Tamron SP 24-70mm f/2.8 Di VC USD verdict
The Tamron 24-70/2.8 VC delivers a pretty good overall performance - only the FX-corners disappoint especially at 35mm. On an unforgiving 36MP full-frame body you need to stop down to f5.6 to lift FX-corner performance to near good levels. Use it on a 12-16MP full frame/FX-body and you might be more satisfied with border/corner performance. Nonetheless the lens is a worthy (not to mention cheaper) alternative to the original manufacturers' offerings. On a DX-body it mostly delivers good to very good performance, even reaching excellent levels in the center (at 50-70mm from f4 onwards).
But there's one thing that definitely sets it apart from the competition: The first image stabilization ever in such a lens! That alone would be worth a recommendation. Canon and Nikon need to rethink their designs and see whether they could equip their professional work-horse zooms with image-stabilization too - or offer bodies with built-in sensor-based stabilization. Tamron's VC extends the useful range for their 24-70/2.8 lens 2-3 stops further into low-light shooting or simply help you avoid shake that could ruin an otherwise perfectly sharp shot - especially on sensors above 20MP (be it APS-C/DX or full-frame/FX). And this in a package that is much cheaper than a lens from Nikon or Canon.
On the other hand there's an even cheaper alternative - at least for Nikon shooters: The new AF-S 24-85/3.5-4.5G VR. It has 2/3 to 4/3 of a stop slower maximum aperture but 20% more reach on the long end. And it performed quite convincingly, as you can read in my Nikon AF-S 24-85/3.5-4.5G VR review, and earned a Recommended rating.
So there's no doubt that the Tamron earns a Recommended rating. But whether this should be upgrade to "Highly Recommended" will only become clear after my up-and-coming Nikon AF-S 24-70/2.8G review and my final 24-xx shootout.
For the time being I have listed the good and bad points of the Tamron 24-70/2.8 VC for you below.
Good to very good image quality in the APS-C/DX image-circle.
Quiet and fast AF operation.
Cheaper than the original manufacturers' 24-70mm f2.8 lenses.
Needs stopping down to f8 to produce good full-frame/FX-corners.
Flare and ghosting not
too well controlled on the long end.
