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. A Full-Time Manual Focus Makes Fine Tuning Easy All Tamron lenses have high auto focus precision and are designed to capture subjects easily and in almost any situation, yet sometimes a photographer wants to fine-tune and make adjustments on the fly.

The integration of a full-time manual focus offers just that: instead of fumbling with switches, photographers can from auto-focus to manual-focus by simply adjusting the focus ring. This feature helps the lens produce impressive results even in telephoto situations where the depth of field is narrow.

Cleaner Crisper Images without Flare or Ghosting The new BBAR (Broad-Band Anti-Reflection) reduce the lens reflection and dispersion that cause ghosting and flare. The coating enhances 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 re-production. Vibration Compensation (VC) Mechanism-Making Telephoto & 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 provides 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 shakes for clean shots night or indoors, or in macro and telephoto situations, hand held has never been this easy.

Speed is Nothing if not Stable Fast and accurate without so much as a whisper. The SP 70-300mm F4-5.

6 Di VC USD is the first to boast Tamron's new Ultra Silent Drive (USD). USD is Tamron's latest autofocus motor technology rotor, converting, converting ultrasonic waves into torque to quietly deliver a new level of focus precision and speed.

Because it's still built on a rotor it's 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. Extra Low Dispersion (XLD) Lens Extra Low Dispersion (XLD) lens elements made from specialized ultra-high-grade glass allow Tamron lens designers to achieve much greater control over chromatic aberration (color fringing) and magnification aberrations, the two major factors that inhibit image quality enhancement.

In combination with LD elements, XLD elements are used to achieve sophisticated lenses that deliver the highest possible contrast, the finest detail, and superior imaging performance throughout the entire zoom range. Full Frame Sensor for Ulitmate Versatility The SP 70-300mm F/4-5.

6 DI VC USD is one of Tamron's Digitally Integrated (Di) designs. The Di series is the mark of Tamron lenses that are format-versatile since they can be used on Digital APS-C, full-frame and 35mm SLR cameras.

Auto-focus/Manual-focus (AF/MF) Switch Mechanism on the Focus Ring The ability to switch quickly between auto-focus (AF) and manual-focus (MF) is a great asset in many types of shooting, especially sports and nature photography. This is easily accomplished with Tamron’s ingenious AF/MF system.

By simply sliding the focus ring back and forth between the two positions you can select either the AF or MF focusing position. In manual-focus mode Tamron lenses provide smooth, precise manual focusing by turning their wide, well-textured focusing rings.

Current as of December 2010. (Source: Tamron).

PZD (Piezo Drive) is a standing wave ultrasonic motor system developed by Tamron. The motor is faster and quieter than DC motors when the AF drive is operated, and compared with ring type ultrasonic motors, it has an actuator that facilitates lens design and reduced size.

The Sony mount is not equipped with the VC image stabilization mechanism, as the body of Sony's digital SLR cameras has a built-in image stabilization function. Consequently, the lens with a Sony mount is referred to as the 18-270mm F/3.

5-6.3 Di II PZD and does not include the VC description.

PZD (Piezo Drive) Ultrasonic motors are divided into two categories depending on the principle that generates the energy to move the drive: traveling wave motors and standing wave motors. Traveling wave motors include the ring type ultrasonic motor used in the recently launched 70-300mm F/4-5.

6 VC USD as well as other lenses, but this lens employs a newer technology, the PZD (Piezo Drive), which functions on the standing wave principle. A standing wave ultrasonic motor utilizes high-frequency voltage to extend and turn the piezoelectric (piezoceramic) element, thus moving the entire element in a standing wave movement.

The metal tip is the contact point of the element to the rotor, and moves in an elliptic motion from the swiveling motion of the moving element, and the friction from this motion turns the rotor. Standing wave ultrasonic motors have the distinct advantage of being smaller than their traveling wave counterparts, and therefore allow a more compact SLR lens size.

VC (Vibration Compensation) Tamron's VC mechanism employs a three-coil system, whereby three driving coils 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 little friction.

This provides a stable viewfinder image with excellent tracking performance that eliminates the blur from handheld shots for cleaner, crisper shots. New VC mechanism (moving coil method) Tamron's original VC image stabilization mechanism utilized a moving magnet system whereby a heavy magnet was positioned near the moving VC lens element.

In the new VC unit the positions of the magnet and the coil are reversed, because of this the VC optical lens element is attached to the coil. The new VC mechanism employs a moving coil mechanism with a lightweight coil, and the lighter coil reduces the load on the drive system.

Thus, the lighter, more compact new VC unit contributes to the lens's overall light weight and compact size. Notice of Classification Code Change for Nikon Mounts Since the introduction by Tamron of the first Nikon mount lens featuring an internal AF motor, the AF28-300mm F/3.

5-6.3 XR Di VC (Model A20), all Nikon mount lenses with the internal AF motor had used the classification code “N II.

” Lenses using a coupler system* without an internal AF motor were designated as “N.” As future lens introductions for Nikon will have the internal AF motor as a standard feature, Tamron has decided to simplify the designation and consolidate all Nikon mount lenses as “N,” eliminating the “N II” designation for future models.

This classification code change will be effective from the 18-270mm F/3.5-6.
