TAMRON SP 70-300mm f/4-5.6 Di VC USD

A005S

Dynamic shots require dynamic lenses.

With an XLD lens element to deliver high resolution, image stabilization and a turbo speed silent autofocus, Tamron's new telephoto zoom makes it easy to capture the most difficult shots. Introducing the new SP 70-300mm F/4-5.6 Di VC USD.

The new optical design of Tamron's advanced telephoto zoom lens delivers a whole new world of possibilities. It allows the photographer to draw the subject close and separate them from their background, creating photographs with spectacular contrast and depth.

This lens also boasts Tamron's USD (Ultrasonic Silent Drive) and proprietary VC (Vibration Compensation) image stabilization. It gives the photographer the ability to capture fast moving subjects without blurring even in low light, and its optical design that employs an XLD (eXtra Low Dispersion) lens element made with specialized glass delivers crisp, clear images with sharp contrast.

Specialized XLD lens elements for extreme high resolution

This lens' optical design employs a sophisticated XLD lens element made from specialized glass that has lower dispersive properties than standard LD (Low Dispersion) lenses (where refraction causes thedispersion of white light into spectral hues).

The dispersive properties of the XLD lens are at a level similar to fluorite, and in combination with LD elements make for an optimal optical design that delivers best-in-class resolution with advanced axial chromatic and magnification aberration correction - major inhibitors of image quality enhancement. The resultis a lens that delivers sharp contrast and better descriptiveperformance throughout the entire zoom range.

Fast focusing USD, the ultrasonic autofocus drive

(Ultrasonic Silent Drive). It achieves faster focusing making this

telephoto lens

perfect for photography of sports, vehicles, and other fast-movingsubjects. With advanced motor technology and software, Tamron's USD

delivers precise and noiseless focusing at turbo speed.

USD is an autofocus motor technology, converting ultrasonic waves into torque to quietly deliver a new level of focusing precision and speed. Because it's still built on a rotor its full time manual focus is as easy as ever; allowing the photographer smooth manual focusing without having to fumble with a switch. This feature helps the lens produce impressive results even in telephoto situations where the depth of field is narrow. With advanced motor technology and newly developed software, Tamron's USD delivers a practical, precise, noiseless photographic experience at turbo speed For those dynamic sports shots, moving vehicles, or fast moving subjects, there has never been a better option.

Equipped with Tamron's VC image stabilization

The SP 70-300mm The SP 70-300mm F5-5.6 Di VC USD (Model A030) employs Tamron's esteemed image stabilization mechanism-VC (Vibration Compensation).

VC is an abbreviation of Vibration Compensation. With VC, the photographer has the freedom to shoot at a shutter speed an extra four stops slower without having to worry about blurring. This makes capturing handheld, evening, night, and interior shots much easier.

The actuator and algorithms, developed in-house at Tamron, provide the power that gives VC it's excellent tracking performance and smooth, stable viewfinder image.

Tamron's VC mechanism employs a three-coil system, whereby the three driving coils activate the shake-compensating VC lens groups 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, helping to eliminate the blur from camera shake for clean shots at night or indoors, or in macro and telephoto photography situations. Handheld was never this easy.

Fluorine Coating for protection and safe cleaning

The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.

Cleaner, crisper images without flare or ghosting.

reflection and dispersion that cause ghosting and flare. The coatings

enhance light transmission in both the short and long wavelength ranges, ensuring excellent performance in all photographic conditions.

Additionally, internal surface coatings are applied to cemented surfacesof all lens elements to deliver sharp, high-contrast images and

flawless color reproduction.
