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 more expensive offerings from Canon, Nikon and Sony.
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
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.
Image sharpness virtually matches the Canon equivalent optic, and the Tamron model is capable of some impressive results.
Tamron AF 24-70mm f/2.8 SP Di USD VC (Canon EOS) - Full Format Review / Lens Test
22 July 2012
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. It is capable of delivering very sharp results at medium aperture settings and at max. aperture the center quality is more than decent.
Tamron AF 24-70mm f/2.8 SP Di USD VC (Canon EOS) - APS-C Review / Lens Test
8 June 2012
Conclusion: The Tamron AF 24-70mm f/2.8 SP Di USD VC already delivered very good results in the full format scope so it's not a surprise that the APS-C results are even better! The resolution characteristic is almost flawless with an excellent center from f/2.8 up to f/8 and a very good outer image region. Lateral CAs are low which contributes to the high sharpness perception. Thanks to the sweet spot behavior on APS-C, the vignetting is nothing to worry about even at f/2.8.
