Product Overview

• Style: Canon

From the Manufacturer In the pursuit to achieve the most outstanding image
resolution in the 70-300mm class, Tamron’s Anniversary lens - the SP
AF70-300mm F4-5.6 Di VC USD - utilizes an advanced optical design that
features an LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element
made from specialized materials that prevent chromatic aberration. As a
result, the SP AF70-300mm F4-5.6 Di VC USD (Model A005) boasts sharper
contrast and greater descriptive performance than all others in its class. In
addition, it is the first Tamron lens sporting a USD (Ultra Silent Drive),
Tamron’s very own auto-focus drive mechanism This USD mechanism delivers fast,
making it a perfect telephoto zoom choice for photographing sports, racing, or
other fast-moving subjects. The lens also boasts Tamron’s proprietary VC
(Vibration Compensation) image stabilization to assist in handheld
photography, not only at long focal length ranges where blurring is common,
but also under low-lit conditions, dramatically enhancing photographic
freedom. This combination of best in class image resolution, Ultra Silent
Drive and Vibration Compensation is a new achievement of Tamron technology
culminating in the production of a premium 70-300mm lens. Tamron SP AF

Discriminating Shooters 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. 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. Technical
