An all-new, high-speed standard zoom lens with image stabilization.
Photographic artists have been waiting for a full-featured, constant-aperture zoom lens. The wait is over. The A007 is a high-quality, highly functional, high-speed standard zoom lens covering the 24-70mm focal range*1. It includes both Tamron's proprietary VC (Vibration Compensation) image stabilization to reduce shake and its USD (Ultrasonic Silent Drive) motor, enabling speedy, silent autofocusing. This SP (Super Performance) series lens makes full use of specialized glass elements in its lens layout, designed with top priority on image quality, including three LD elements and two XR (Extra Refractive Index) glasses. Tamron has minimized all types of chromatic aberration in the A007, making it a lens at the top of its class whether you use it on a digital APS-C, full-frame, or 35mm SLR camera. The A007's F/2.8 aperture enables a balance between brilliant resolution and beautiful soft blur effects. This ideal lens makes full use of Tamron's rounded diaphragm*2 and the uncontrived, artistic blur that it provides. It is also Tamron's first lens to feature our new moisture-resistant construction. Portraits. Landscapes. Studio shoots. This is the lens for them all. Capture the finest details of your images in precisely the way you have always wanted to. Extend your art to the limits of your inspiration with the A007.
*1 With SLR cameras corresponding to APS-C, the angle of view based on 35mm equivalent focal length will range from 37mm to109mm.
*2 This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.
Technologies for Top-flight Definition, Ease of Use
The world's first* F/2.8 high-speed standard zoom lens with image stabilization. An all new VC (Vibration Compensation).
This F/2.8 high-speed lens is equipped with a VC (Vibration Compensation) system that provides a stable image that seems virtually pasted onto the viewfinder. Even under low-light conditions, handheld shooting without concern for camera shake is made possible. Tamron's VC is a three-coil system, whereby three driving coils activate the shake-compensating VC lens group electromagnetically via three ceramic balls. The VC lens elements are held in place only by contact with the ceramic balls, achieving smooth movement with little friction. This provides a stable viewfinder image with excellent tracking performance. 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.
VC is also available in the 17-50mm[B005], 18-200mm[B011], 18-270mm[B008], 28-300mm[A20], and 70-300mm[A005] models.

All Tamron lenses have high autofocus precision and are designed to capture subjects easily in almost any situation, yet sometimes a photographer wants to fine tune and make adjustments on the fly. The integration of full time manual focus offers just that: instead of fumbling with switches, photographers can switch from autofocus to manual focus by simply adjusting the focus ring. This feature helps the lens produce impressive results even in telephoto situations where the depth of field is narrow.
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. The result is a lens featuring low noise and high-torque, highly responsive, speedy focusing.
Moisture-resistant construction is added to help keep water from penetrating the lens. It's ideal for outdoor photography.
Strengths of the F/2.8 high-speed lens
High-speed lenses are bright, highly sensitive lenses that are able to take in a large amount of light. The high-speed Model A007 makes use of such brightness to deliver a number of different artistic advantages.
As high-speed lenses produce an extensive blurred effect in the areas outside of the focused field, the photographer can greatly blur the foreground and background and thus highlight the main subject in focus, to create an image with realistic depth. In developing this lens, attention was also paid to the shape of the diaphragm blades, which affects the form of the blur. The diaphragm blades maintain a near-perfect circular shape up to two stops down from the fully open state, the position frequently used for creating the blurred effect, adopted the rounded diaphragm to enable exquisite blurred-effect images.
Compared with slower-speed lenses, when high-speed lenses are used images may be taken at shutter speeds that are 1-2 stops faster. Moreover, Tamron's proprietary VC (Vibration Compensation) mechanism delivers anti-shake benefits of up to 4 shutter speed stops*. The combination of VC with the benefits of the high-speed lens enables hand-held photography even in cases where it normally would not have been possible without using a tripod.
* The compensating effects of VC will vary depending on photographer and photographic conditions.
Tamron's conversion value is 1.55 x.
The SP 24-70mm F/2.8 Di VC USD is one of Tamron's Di (Digitally Integrated) designs. The Di Series is the mark of Tamron lenses that are format-versatile since they can be used on digital APS-C, full-frame and 35mm SLR cameras.
