This is one of the best standard zoom lens that every serious full frame DSLR owner should have. And if you already have a full frame body, you should be a serious photographer. This is the most used zoom range for landscapes, indoors and parties.

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Nice Bokeh

This Lens isn't light but what do you expect from a 2.8 right Lens arrived super fast which was great and compliments my D610 very well. The picture quality from this lens is fantastic, I saw videos on youtube comparing this to the nikon, I was a little skeptical but now seeing it in action its...

Walk-around, portrait, and indoor lens with fast f/2.8 capability. Replaced (returned) the Sony Zeiss 28-70 f/2.8 for this lens because (a) it cost $ more, and (b) it was 'sloppy' when attached to my Sony SLT A99 at the lens/body interface...it moved at the extreme focal length ranges..

I took an egg away for the somewhat slow AF and lower image quality (Compared to the Canon). Don't get me wrong though: If you use stabilization a lot this is an excellent choice and bargain! The image quality honestly is quite good (just not as good as the Canon).

Vibration Compensation works great Fast 2.8 Accurate Auto-Focus (on my Canon T3i

Not as good image quality as the Canon 24-70 2.8L II (but close; I think it is at least as good as the Mark I) Auto-Focus seems slow, and not accurate good in AI Servo $1000 or so less than the Canon

Great build, feels strong, and weather sealing is good addition. VR is great for low light situation. Autofocus is slow in low light however, and image quality is not as crisp as the nikon.

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.
