Tamron’s SP 24-70mm f/2.8 DI VC USD Lens for Nikon Cameras delivers a very useful range from 24mm true wide-angle to 70mm short telephoto, useful for landscapes, interiors, portraits, street photography and much more. The continuous maximum aperture of f/2.8 combined with built-in Vibration Compensation image stabilization make it possible to achieve stellar results in low-light situations, while the Ultrasonic Silent Drive (USD) gives you very quiet autofocus capabilities that are ideal for shooting video.
Its headline feature is indicated by the ‘VC’ in its name, which stands for ‘Vibration Control’; it’s the first and only optically-stabilized fast normal zoom for full frame cameras. As befits a premium SLR lens it also includes an ultrasonic-type autofocus motor for fast and silent focusing, and as an added bonus it features a degree of weathersealing (Tamron uses the term ‘drip proof’). Put together, this makes it the highest-specified 24-70mm lens currently on the market.
To achieve this feat, Tamron has employed an exotic optical formula that makes extensive use of special elements. It includes three Low Dispersion (LD) glass elements, two Extra Refractive Index (XR) glass elements, three glass molded aspheric elements, and one hybrid aspherical element in its 17 element / 12 group design. A 9-bladed aperture diaphragm uses curved blades for the attractive rendition of out-of-focus backgrounds.
