A popular lens choice for full-frame camera users is the 24-70mm f/2.8 optic, because its range covers general use and the fast aperture is constant throughout the entire focal range. Indeed, most camera retailers recommend it as the lens to buy with a full-frame camera as part of a kit.

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

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.

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 recently purchased this lens form Ted's. I will keep this review as simple as possible: Build quality: Very good. Compares to Canon 100 f/2.8 macro, and even feels a tad better built. Also comes with moisture sealing which is very important since the lens extends when zooming.

Easy to use

The Tamron SP 24–70mm f/2.8 Di VC lens is a fast lens designed to work with full-frame cameras (but it will work with smaller sensors, too). It's available for Canon, Nikon, and Sony; however, the Sony version doesn't include vibration compensation (VC) because Sony DSLRs already have that feature...

Image quality; VC; price

Very slight vignetting and barrel distortion

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.

At the time I bought this lens I needed a high quality 24-70mm f2.8 or faster, with vibration control. I shoot Canon products and read all the reviews. Canon came up short, and did not have a 24-70mm f2.8 with IS. Canon did have a f4 model, but I needed the extra stop.

The Tamron SP 24-70mm f/2.8 Di VC USD is a new 2.9x zoom that was announced April 2012 and is the first ever stabilized large-aperture standard-zoom compatible with full-frame DSLRs.

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?
