Im very surprised with the quality of this lens, im using this lens for video and is awesome!! very Robust, excellent build quality, the image quality is great!! super sharp and bright.

The price is enormous high for the qualilty of images. I compared this lens with my old cheap soligor 3,5-4,5/28-70. Contures of the old one are real sharp in the corners and CA's are very low, but not this lens. I regret:: this is a p o r t r a i t lens.

at such a high price I expect high sharpness still with open lens up to the corners of image; But even with f 4,5 you get not real sharp corners on 28mm; Like the concurring product of Sigma double contures in the corners and too much CA's.

nice colors,quite good sharpnes in the center; high contrast

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; Bokeh can be objectionable in some situations

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.

As the only 24-70mm f/2.8 currently on the market that has image stabilization (VC as Tamron calls it, or VR in Nikon parlance) this lens is a no-brainer as the best choice for DSLR video. Value is unmatched compared to Nikon's version which is $500 more expensive WITHOUT image stabilization.

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

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.

The difference between a "constant" aperture zoom and other standard zooms is that when you increase the focal length on the standard zoom the maximum aperture narrows. This might make the difference between being able to hand hold or not when zooming in, and may indeed force the use of higher ISOs.

Bought this Ripper Lens this morning and was shooting this afternoon at my kids sports event. I'm very happy with my choice of lens. After deliberating and watching many comparisons I just had to get this lens for the special price CD's had it at with the 2yr warranty.

This Tamron lens is more than suitable as an alternative to Canon's flagship 24-70 f/2.8 II. The lens is solid, well built, tack sharp, and has the benefit of IS! Images produced have wonderful color and clarity.

Wonderful color; Tack sharp; Nice Solid Build

Zoom ring a little stiff
