This is a fantastic lens & I'm generally a canon L lens type of a guy. That been said I believe in using the best tool that gets the job done.Build quality is really solid & the addition of VC is great, it's f2.8 constant aperture on Full Frame & it's the only on in the world to date with...

VC works great Silent operation High quality finish Good weight; balances well on 5d Mk11 Amazing image quality

I reckon that the Tamron designers had some fun during the design of the lens. Unlike with the Tamron AF 28-75mm f/2.8 SP XR they were not so much restricted by pricing concerns and the positive effect on the results is obvious - the Tamron AF 24-70mm f/2.8 SP Di USD VC is an impressive lens.

A popular lens choice for full-frame camera users is the 24-70mm f/2.8 optic, because its range covers general use and the fast aperture is constant throughout the entire focal range. Indeed, most camera retailers recommend it as the lens to buy with a full-frame camera as part of a kit.

I recently purchased this lens form Ted's. I will keep this review as simple as possible: Build quality: Very good. Compares to Canon 100 f/2.8 macro, and even feels a tad better built. Also comes with moisture sealing which is very important since the lens extends when zooming.

Easy to use

The Tamron SP 24-70mm f/2.8 Di VC USD is a new 2.9x zoom that was announced April 2012 and is the first ever stabilized large-aperture standard-zoom compatible with full-frame DSLRs.
