Unparalleled optical performance in a
fast-focusing, steady telephoto zoom lens

This full-size premium telephoto zoom with Extra Low Dispersion (XLD) element delivers best-in-class resolution, while Tamron’s own Ultrasonic Silent Drive (USD) and Vibration Compensation (VC) make the lens fast, quiet and easy to use.

Designed for digital SLR cameras, it can be used with both full-frame sensor and AF 35mm cameras for a zoom range of 70-300mm. With APS-C sensor cameras the angle of view will change the zoom range to an equivalent of 109-465mm*.

* Tamron’s conversion 1.55x.

Aspiring to the most outstanding image resolution in the 70-300mm class, this lens utilises an advanced optical design featuring an LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element made from specialised materials that prevent chromatic aberration. As a result, it boasts sharper contrast and greater descriptive performance than all others in its class.

It's also the first Tamron lens sporting a USD (Ultrasonic Silent Drive), Tamron’s very own ultrasonic autofocus drive mechanism. This USD mechanism delivers fast focusing, making it a perfect telephoto zoom choice for photographing sports, racing and other fast-moving subjects.

The lens also boasts Tamron’s proprietary VC (Vibration Compensation) image stabilisation to assist in handheld photography, not only at long focal length ranges where blurring is more common, but also under low-lit conditions, dramatically enhancing photographic freedom.

This combination of best-in-class image resolution, Ultrasonic Silent Drive and Vibration Compensation takes Tamron technology to a new level.

MAIN FEATURES

1. A new optical system optimised for digital cameras achieves top resolution in the 70-300mm class with specialised glass elements

The advanced optical design employs a sophisticated XLD (Extra Low Dispersion) lens element made from a special high-grade glass that has dispersive properties (i.e. where refraction causes the dispersion of white light into spectral hues) even lower than standard LD lenses. The dispersive properties of the XLD lens are similar to those of fluorite; in combination with the LD elements, these 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.

2. 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, motor racing and other fast-moving subjects. With advanced motor technology and newly developed software, Tamron's USD delivers precise, noiseless focusing at turbo speed.

3. Equipped with Tamron’s VC (Vibration Compensation) image stabilisation

The SP AF70-300mm F/4-5.6 Di VC USD employs Tamron’s renowned image stabilisation mechanism – the VC (Vibration Compensation) seen in both the AF18-270mm Di II VC (Model B003) and SP AF17-50mm F/2.8 XR Di II VC (Model B005). With VC, the photographer has the freedom to shoot at a shutter speed that is an extra four stops slower without having to worry about image blurring. This makes handheld capture of evening, night and interior shots much more spontaneous, as a sharp image can be obtained more easily without having to mount the camera on a tripod.

4. Full-time manual focus at your fingertips

Autofocus has many benefits but sometimes the photographer needs the control of manual focus. Full-time manual offers just that: the crossover from auto-focus to manual focus by simply adjusting the focus ring, allowing the photographer to make adjustments on the fly. This feature helps the lens produce impressive results even in telephoto situations where the depth of field is shallow.

5. Internal focusing provides better balance and consistent length

When focusing, the internal elements of the lens move and the lens’ external size does not change. This offers better balance and easier telephoto shots. Moreover, the barrel is not subject to stray light entering from external helicoids that can adversely affect image quality. And because the external elements do not move, it makes it easier to utilise filters such as polarisers and the supplied flower-shape lens hood to control the amounts and angles of light entering the lens.

6. Enjoyable photography for a wide range of enthusiasts using all types of SLRs

With a full-frame digital or 35mm SLR, portrait and medium telephoto shots can be achieved on the wider 70mm end of the range and spectacular telephoto shots at the longer 300mm. When using an APS-C sensor camera the angle of view narrows, giving it the equivalent range of 109-465mm* for bold ultra-telephoto shots. And with its maximum magnification ratio 1:4, the lens can be used to explore the realm of semi-macro photography.

7. Uncompromising countermeasures to reduce ghosting and flare

Digital photography requires extreme precision, which is why Tamron incorporates new BBAR (Broad-Band Anti Reflection) multilayer coatings that reduce reflection into the lens elements. This ensures excellent performance in all photographic conditions and enhances light transmission on both long and short wavelengths. Also, Tamron applies internal surface coatings on cemented surfaces of lens elements to make images sharper with better colour balance and reproduction.

8. Simple yet attractive exterior design

For this lens Tamron has adopted a streamlined silhouette to ensure that this lens looks good with a variety of SLR cameras. The subtle texture of the paint gives a well-crafted finish to the exterior.

9. Flower-shaped hood with excellent stray light shielding properties as a supplied accessory

The Flower-shaped Lens Hood is designed to block out damaging light rays, ensuring clear, sharp images.

SPSuper Performance series

Tamron SP (Super Performance) series is a line of ultra-high-performance lenses designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. In creating SP lenses Tamron’s optical designers put their foremost priority on achieving superior performance parameters – they are all designed to a higher standard with little regard for cost constraints. As a result, Tamron lenses bearing the SP designation feature impressive and innovative designs that have established an enviable reputation for excellence among those knowledgeable photographers that demand the very best.

VCVibration Compensation

Tamron's unique VC mechanism uses a proprietary actuator and algorithms to deliver an extremely stable viewfinder image with excellent tracking. The mechanism employs three driving coils which activate the shake-compensating VC lens group electromagnetically via three steel balls. The VC lens elements are held in place only by contact with the steel balls, achieving smooth movement with minimal friction. The simplicity of this mechanical structure is also one of the secrets of Tamron's compact lens sizes.

Vibration Compensation mechanism in Tamron lenses

USD Ultrasonic Silent DriveUltrasonic Silent Drive

Tamron’s USD works with the high-frequency ultrasonic vibrations that are produced by a ring called a ‘stator’. Energy from the vibrations is used to rotate an attached metallic ring known as the ‘rotor’. Piezoelectric ceramic is a material that produces ultrasonic vibrations when voltage of a specific frequency is applied is arranged in a ring formation on the stator. This electrode configuration of piezoelectric ceramic causes two ultrasonic vibrations to occur in the stator. By effectively combining these two ultrasonic vibrations, it is possible to convert the energy from the vibrations that produce simple motion into energy known as ‘deflective travelling waves’, which move around the circumference of the ring. The friction between these deflective travelling waves created on the metallic surface of the stator and the surface of the rotor produces force, causing the rotor to rotate. Attached to the rotor is the focusing lens, which is given a fast, smooth autofocus movement.
