Tamron's latest zoom lens covers the popular 24-70mm focal length span with a fast maximum aperture that remains at f/2.8 throughout the range. The SP 24-70mm f/2.8 Di VC USD is designed primarily for cameras with 36 x 24 mm sensors but, being a 'Di' lens, it is usable with APS-C camera bodies.

The Tamron lens, with an f2.8 constant maximum aperture, is in the category of "standard" zoom for a full frame DSLR. It can be used on a reduced sensor APS camera, where the focal lengths then become 36–105mm.

A fast, sharp, image-stablized 24–70mm zoom lens is just what serious photographers have been crying out for but so far the major camera manufacturers have not answered their pleas.

Sharp; Image-stabilized; Well built; Dependable

Rear focus ring hinders; steadiness

I saw this lens reviewed and advertised and it seems to be the only alternative to the Nikon 24-70 f 2.8. I really want/need VC (VR), but I doubted that the Tamron optical quality would be acceptable. Up till now, I have only bought Canon or Nikon lenses (not including my view camera lenses).

Simply Better than the Nikon 24-70 f2.8 and much less expensive; Better center sharpness, better corner sharpness, better resistance to flare, better micro-contrast, better color, and of course it has VC as a bonus

Image quality unacceptable in corners, needs to be better; I need better image quality, even if I have to pay more to get it.

I bought this on the strength of various reviews in magazines. At the time I already owned the more expensive Nikon 24-70 f/2.8 lens, however I felt my Nikon 24-70 lens gave slightly underexposed results.

Consistent Output; Durable; Easily Interchangeable; Image Stabilization; Lightweight; Quick Focus; Rugged; Sharp Focus; Strong Construction

Nowhere on the website does it say it's a grey import. do not expect proper warranty cover!

The Tamron SP 24-70mm F/2.8 Di VC USD is distinguished by being the first fast standard zoom for full frame cameras to include optical image stabilization. The fact that it does so in a design that includes a ring-type ultrasonic motor for fast, silent autofocus and a degree of weathersealing...

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

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

After one year of regular usage the wide rubber band, the one you spin to zoom, stretched and became loose and now moves along the lens so I need to pull it back, where it should be, every 30 min. It does not affect good image quality but I would never buy a Tamron lens again.

Simply put, you won't find a better 24-70 on the Nikon side for this little. Sigma may have theirs, but the image stabilization isn't NEARLY as effective.

Great sharp lens. I bought it because it was cheaper than the Nikon equivalent, but this also has VC which no other 24-70mm has on the market.
