Tamron SP AF 70300mm f/45.6 Di VC Open Box Lens
A New Benchmark in Telephoto Zoom Lens Design
This premium, state-of-the-art, telephoto zoom lens is the culmination of decades of outstanding innovation in ultra-long-range zoom optics by Tamron. It provides professional and enthusiast users of full-frame and APS-C format digital SLR cameras with the ultimate in image quality and handling in the telephoto zoom class. Built to exacting SP (Superior Performance) standards, it delivers ultra-high resolution across the image field at all focal lengths, along with the first-ever USD (Ultrasonic Silent Drive) for extraordinary auto-focusing speed and responsiveness. To assure razor sharp imaging when shooting handheld, the SP 70-300mm incorporates VC (Vibration Compensation), Tamron's exclusive low-friction tri-axial image stabilization system acclaimed for its unsurpassed anti-shake performance.
Description
Highly specialized XLD lens elements for extreme high resolution.
This lens' advanced optical design employs a sophisticated XLD (Extra Low Dispersion) lens element made from specialized high-grade glass that has lower dispersive properties than standard LD lenses (where refraction causes the dispersion 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 result is a lens that delivers sharp contrast and better descriptive performance throughout the entire zoom range.
Fast and accurate, without so much as a whisper.
USD is Tamron's latest 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.
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.
Making telephoto and low light a new medium.
The actuator and algorithms, developed in-house at Tamron, provide the power that gives VC (Vibration Compensation) 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.
