The Tamron 24-70mm f2.8 Di VC USD SP Lens is a high-speed, standard zoom, Super Performance (SP) Lens with built-in Vibration Compensation (VC) and Ultrasonic Silent Drive (USD). Tamron’s VC enables you to shoot hand-held in dimly lit conditions and use speeds up to four stops slower than normal. This compact, lightweight lens incorporates special high-grade glass in three LD elements, three glass molded aspherical lenses, one hybrid aspherical lens and two Extra Refractive (XR) elements to deliver exceptional images. The USD provides quick AF (Auto Focus) that’s quiet, together with full-time manual focus override. Along with its moisture-resistant construction, the Tamron 24-70mm f2.8 Di VC USD SP Lens is equipped with a fast maximum aperture of f2.8 to ensure natural out-of-focus areas with a shallow depth of field.

February 2013 - Tamron have given photographers another choice to consider when looking at a standard zoom. But can its specifications on paper live up to the hype and be a viable alternative to the industry standard 24-70mm zooms out there whilst maintaining a similar size and weight and all at a very competitive price point? That’s a tall order.Read the Tamron 24-70mm review on the Wex Blog... »
VC (Vibration Compensation)
VC (Vibration Compensation) is Tamron’s proprietary image stabilization system. Tamron’s VC is a three-coil system, whereby three driving coils activate the shake-compensating VC lens group electromagnetically via three steel balls. The VC lens elements are held in place only by contact with the steel balls, achieving smooth movement with little friction. This provides a stable viewfinder image with excellent tracking performance. And as the VC lens may be moved in parallel using only the motorized control, the mechanical structure has been simplified, enabling the creation of a more compact lens.
New VC system (moving coil method)
Tamron’s original VC image stabilization mechanism utilized a moving magnet system whereby a heavy magnet was positioned near the moving VC lens element. In the new VC unit the positions of the magnet and the coil are reversed, because of this the VC optical lens element is attached to the coil. The new VC mechanism employs a moving coil mechanism with a lightweight coil, and the lighter coil reduces the load on the drive system. Thus, the lighter, more compact new VC unit contributes to the lens’s overall light weight and compact size.
Because the 24-70 mm F/2.8 Di VC USD is a high-speed zoom lens with maximum aperture of F/2.8, its VC system must drive a lens that is larger and heavier than other zooms. Therefore, the shape, size and layout of the drive coils are all designed to obtain sufficient thrust. The result is a full-size, high-speed zoom that provides the same high level of compensation effect.
Digitally Integrated Design - A Generation of lenses designed for optimized use with digital SLR cameras (APS-C format and full-frame) by means of superior designs and multi-coating techniques. The same outstanding performance is also achieved with conventional cameras.
USD ( Ultrasonic Silent Drive)
Tamron’s USD works with high-frequency ultrasonic vibrations which are produced by a ring called a ‘stator’. Energy from the vibrations is used to rotate an attached metallic ring known as a ‘rotor’. Piezoelectric ceramic, an element that produces ultrasonic vibrations when voltage of a specific frequency is applied is arranged in a ring formation on the stator. This electrode configuration of piezoelectric ceramic causes two ultrasonic vibrations to occur in the stator. By effectively combining these two ultrasonic vibrations, it is possible to convert the energy from the vibrations that produced simple motion into energy known as ‘deflective traveling waves’, which then moves around the circumference (rotation direction) of the ring. With the USD, the friction between these deflective traveling waves created on the metallic surface of the stator and the surface of the rotor produce force, causing the rotor to rotate. The focusing ring of the lens, which is linked to the rotor, is thus moved, creating a fast and smooth auto-focus drive.

Only niggle is the size of the filters the lense takes. Sharp. Balances the 6D nicely. Fast.

As a general all purpose lens this is hard to beat, almost half the price of it's nearest rivals.

Read reports on the quality of the lens before I brought and haven't been disappointed using it
Excellent for an independent make.
By Race bike Steve
Brillient lens in most repects, focus may be slower than Canons L series but not by much. Zoom control does not have the smooth feel of Canons L series.

I have been wanting to upgrade to a faster / large aperture lens for some time. As a hobbyist, the cost has been prohibitive though. "Luckily," my kit lens has recently given up on me, providing the push I needed to upgrade.The Canon offering was outside my budget, leaving this lens and a Sigma equivalent (which was £200 cheaper, but without stabilisation) to choose from. Reading several internet reviews rapidly excluded the Sigma from my (very!) short-list.Although it is a large and bulky lens, this is not a problem in use (although it can be difficult to squeeze into my camera bag).The focal range is perfect for normal use. Lens background blur is excellent and the low light performance seems good.Focus is quick and silent and there is even an included lens hood and a five year guarantee.Although pricey, this lens is really great value, when compared to the price of the Canon equivalent. I really can not fault it!

Great, natural, low light photographs
About Me Casual user
I use a 60d, I already have a prime 50mm and a prime 85mm lens and was not sure I would find this lens up to much so I'm really pleased to find that I love it. I think it's the zoom element for framing that makes it so much better than a fixed prime. The f2.8 using spot metering is great for natural indoor low light shots of fast moving children. So far, I have only used it at f2.8 and so slightly disappointed with sharpness but that may well be more to do with my skills than the lens. It returns some great colour and I love the results. For me, it was fast enough to lock on and focus in AI mode and at 70mm the background blur effect is really special.
