New SP 24-70mm f/2.8 Di VC USD lens from Tamron

For the CP+ show in Japan Tamron announced a new SP 24-70mm f/2.8 Di VC USD lens that will be offered in Canon, Nikon and Sony mounts (Sony's version is without vibration compensation).

Press release:

Tamron develops full-size, high-speed standard zoom with built-in image stabilization – SP 24-70mm F/2.8 Di VC USD (Model A007)

February 6th, 2012, Saitama, Japan - Tamron Co., Ltd., a leading manufacturer of optical equipment, announced the development of the SP 24-70mm F/2.8 Di VC USD (Model A007), a full-size high-speed standard zoom lens equipped with VC ( Vibration Compensation) image stabilization and USD ( Ultrasonic Silent Drive), with resolution at the top of its class.

The price and availability of the SP 24-70mm will be announced at a later date.

Product Features

1. A full-size, high-speed standard zoom with built-in VC ( Vibration Compensation). Even when shooting in low-light conditions with a slow shutter speed to render sharpness, Tamron’s acclaimed VC allows for stable handheld camera work, to more fully enjoy the benefits of this high-speed zoom lens.

2. Uses special high-grade glass in the three LD elements, three glass molded aspherical lenses, one hybrid aspherical lens and two XR (Extra Refractive Index) glasses, delivering top-of-the-class quality images suited to this high-grade lens. Using a rounded diaphragm, the lens achieves gorgeous blur effects. This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.

3. Features Tamron proprietary USD ( Ultrasonic Silent Drive) to power a speedy AF drive together with a continuous manual mechanism.

4. This high-speed standard zoom lens has a wide-end focal length of 24mm that expands the photographic area.

5. The lens adopts the new technology including the latest optical design, VC ( Vibration Compensation) image stabilization and USD ( Ultrasonic Silent Drive), all in a lighter and more compact package.

6. Moisture-resistant construction helps prevent water from penetrating the lens.

* Length, entire length and weight values given are for the Nikon mount.
* Entire length is the distance between the tip of the lens and the tip of the protrusion.
* The Sony mount does not include VC, because the body of Sony digital SLR cameras includes image stabilization functionality. The product name for Sony cameras is “SP 24-70mm F/2.8 Di USD” without the VC designation.

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.

About the ultrasonic motor
In the ultrasonic motor, a piezoelectric element arranged in a ring formation generates ultrasonic vibrations in a metallic ring stator, and the vibration energy is used to rotate a metallic ring rotor that is attached to the stator. The rotation energy is in turn transferred from the metallic ring rotor to operate the focus lens.

    wow

  • jason

    I may take the risk to sell my Nikon 24-70 ! This is tempting!

    Wonder what would be response from Nikon

  • blueget

    Now that’s interesting… especially for Canonists, especially regarding the year-long rumors of a EF 24-70 L IS/II.

  • fujiwara

    If this is better than the 28-75 that they have then i will buy it

  • Rasmus Zetter

    I’m guessing that this will not replace their 28-75, but rather fill a quite obvious market gap. It will probably also be priced thereafter, I’m guessing around 900-1000 USD.

  • Kevin

    This is the Canon lens I have been waiting for. I want to see the test results first.
    Also I want to see the mk II 24-70. It reportedly is still missing IS/VC.

  • Camaman

    !Out of the blue!

    Why don’t we get any Tamron rumors…?

  • fants

    Wow – so the first company to make a 24-70 2.8 IS is Tamron. Hopefully it doesn’t have the same corner softness as their 28-75, but rather the incredible quality of the 17-50!

  • Zeusman

    This looks like it will be my first non-L lens purchase. Very Cool!

  • FMJ

    to add a VC in the 24-70 range, this will sell pretty well for Canon & Nikon shooter, especially their own 24-70 has no IS/VR.

    but i prefer the 28-75 range more since its a bit closer to the portrait range, + this use a massive 82mm diameter filter, this will probably kill some purchase.

    i would prefer they add a silent motor to the 28-75

    • Rover

      More and more lenses are coming out in 82 mm filter size (Canon’s 16-35 II, 24 TS-E II, now 24-70 II; Tokina’s 17-35 and more). It looks inevitable so there’s no use fretting over filter sizes.

      This lens looks very interesting. I believe that if the IQ is up there (and I don’t see why not) it’ll sell like hotcakes to those who don’t feel like red ring is the only worthy thing on the planet. Especially since Tamron upstaged Canon by putting stabilization in their lens while Canon only releases a refreshed version of the same lens and the improvement in IQ is not yet made obvious.

    Definitely worth it!

    I cant wait for them to make the 70-200 f2.8 range or this caliber. I dont mind if they make the hebrew trinty tamron style! Im the first one to have that for sure! More power tamron!

  • ken

    No Pentax version again? What’s going on Tamron???
    This looks like a worthy replacement of the 28-75 if the optics are as good…

  • No Love For Pentax

    Looks like Tamron has dropped support for Pentax as well. A shame, really. First Zeiss drops their excellent ZK line of manual focus primes and now this. It must have been due to poor sales figures. Heck, they are producing a version for Sony without VC, seems like they could (easily?) do similar in a K-mount. It’s too bad, as this is a lens which would compliment the existing Pentax line of DA* zooms nicely.

  • an onymous

    Wow, looks good on paper so far!

    Considering the optical quality of Tamron’s 70-200/f2.8 which is sharpest already at f4 with a nice bokeh and very good chromatic aberration control which even Nikkor VRII equivalent can be jealous of, this is a lens to watch out for, that is when the real world picture samples will show its real qualities!

    I really hope Tamron have sorted out the AF problems CONSIDERABLY!! as their 70-200/f2.8 is very hesitating and often out of focus starting already at slight dim light conditions, hopefully Tamron will soon upgrade their 70-200 as well.

    • Rover

      Actually I hope they’ll get to updating their 70-200 (and some other lenses) with USD (and VC where appropriate). Their second lens with ultrasonic motors means they’re serious about this – the 70-300 looked more like they were testing the waters. The list is endless – 17-50, 60/90/180 macros, 200-500, 17-35…

    Wonder when DP will do a test on this thing. Looks freaking Yummy!
