Dynamic shots require high-perfomance telephoto zoom 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 new optical design that employs an XLD (Extra Low Dispersion) lens element made with highly specialized glass delivers crisp, clear images with sharp contrast.
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 focusing USD (Ultrasonic Silent Drive), the ultrasonic autofocus drive
The lens is equipped with Tamron's first-ever ultrasonic autofocus drive USD (Ultrasonic Silent Drive). It achieves faster focusing making this telephoto lens perfect for photography of sports, vehicles, and other fast-moving subjects. With advanced motor technology and newly developed software, Tamron's USD delivers precise and noiseless focusing at turbo speed.
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.
Equipped with Tamron's VC (Vibration Compensation) image stabilization
The SP 70-300mm F5-5.6 Di VC USD employs Tamron's esteemed image stabilization mechanism-VC (Vibration Compensation) for upto 4.0 stops benefit (CIPA Standard). 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 (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.
Cleaner, crisper images without flare or ghosting.
The BBAR (Broad-Band Anti-Reflection) coatings reduce the lens 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 surfaces of all lens elements to deliver sharp, high-contrast images and flawless color reproduction.
Developed for industrial optics, fluorine coating offers long-lasting oil and water resistance to the lens. Moisture and smudges wipe away, making it easy to keep your lens clean.

MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.
The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.
Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.
Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance.
