Excerpt: This highly anticipated lens from Tamron covers the popular 24-70mm range with a fast constant aperture of f/2.8. It is one of Tamron's 'SP' lenses, which denotes that it should be able to produce professional quality results.
Excerpt: With smooth bokeh and a versatile zooming range, both Nikon and Canon full-frame shooters (e.g. Nikon D700 and Canon 5D Mk II) have continually relied on their respective 24-70mm f/2.8 lenses. The only problem?
Summary: The Tamron SP 24-70mm F/2.8 Di VC USD is the first fast standard zoom for full frame cameras to feature optical image stabilization. Its combination of impressive optics, effective autofocus and image stabilization systems, and drip-proof construction makes it a compelling alternative to the much...
Pros: Extremely good optics, Highly effective image stabilization, Silent, accurate focusing, Impressive flare resistance, Very good build quality including sealing, Competitive price compared to camera manufacturers' equivalents
Cons: Unpleasant vignetting at F2.8 on full frame at the telephoto end, Slightly less-fast autofocus than Canon or Nikon equivalents (but far from slow), AF and VC switches rather stiff, difficult to change quickly
Excerpt: The announcement of the Tamron 24-70mm f/2.8 Di VC USD Lens raised more than a few eyebrows. For many years, photographers (including me) have been requesting a full frame compatible 24-70mm f/2.8 lens with optical image stabilization.
Tamron SP 24-70mm F/2.8 Di VC USD: A Constant Aperture “Full Frame” Zoom
1 May 2006
Summary: Okay, I would have preferred the lens to accept 77mm instead of 82mm filters, since my accessories top out at 77mm, and large glass circular polarizers are an expensive proposition, but that’s the price you pay for fast glass. That said, I never once felt at cross-purposes with the lens.
Summary: Image stabilisation is deemed surplus by many in a lens like this, but I find it useful for low-light work as it increases the versatility of this high-quality, general-purpose optic. Build quality is good, although I would like to see a couple of tweaks to the handling, such as a wider focus ring.
Conclusion: The Tamron SP 24–70mm f/2.8 Di VC USD lens does what its big-name competitors can’t do. It allows you to take sharper handheld photographs in all lighting conditions without compromising quality.
Pros: Sharp, Image-stabilized, Well built, Dependable
Excerpt: The Tamron SP 24-70mm F/2.8 Di VC USD features a USD (Ultrasonic Silent Drive) that allows near-silent auto-focusing. Importantly, this solution allows instant manual override even when the focus mode switch is in the AF position.

Conclusion: 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.
