Took the plunge and pre-ordered the Tamron AFA011N700 SP 150-600mm F/5-6.3 Di VC lens from Amazon. A zoom in this range from Nikon is simply not affordable to casual photographers like myself.Â The $1000 price tag of this Tamron is much easier to justify. Having had wonderful results with the super inexpensive Tamron SP 70-300MM F/4-5.6 Di VC USD did not give me much concern for quality. Third party lenses have come a long way. The only risk with these lenses is forward compatibility with newer bodies. That will remain an issue until all lenses include a means to upgrade the firmware. Anyhow all that is a discussion for another day. I eagerly await the lens to arrive in my hands shortly. For now you can read more about it and view sample images at the Tamron website.
Zoom up to 600mm for images that soar Capture the power and beauty of wildlife, birds, travel destinations, and exciting sports action close-ups with this high-performance 150-600mm long-range zoom. VC (Vibration Compensation) and USD (Ultrasonic Silent Drive) enable you to shoot crisp images of fast-moving, distant subjects handheld, while proprietary Tamron optical technology, including eBAND Coating, works to suppress flare and ghosting for impressively clear, vibrant images.
Advanced Optical Technology Three LD (Low Dispersion) elements are effectively deployed to correct chromatic aberrations, a challenging problem when shooting at long distances and at long focal-length settings. Tamron’s eBAND Coating and BBAR (Broad-Band Anti-Reflection) Coating help suppress flare and ghosting for class-leading image quality.
VC (Vibration Compensation) VC (Vibration Compensation) is Tamron’s proprietary image stabilization system. Tamron’s VC is a three-coil system, whereby three driving coils activate the shake-compensating VC lens group electromagnetically via three ceramic ball bearings. The VC lens elements are held in place by contact with the ceramic ball bearings, achieving smooth movement with little friction. And since the VC mechanism is moved in parallel using only the motorized control, the mechanical structure has been simplified, enabling the development of a more compact lens.
USD (Ultrasonic Silent Drive) The quiet high-torque USD motor ensures a speedy and accurate autofocus response.
New eBAND (Extended Bandwidth & Angular-Dependency) Coating This new coating technique developed by Tamron deploys a nano-structured layer (1 nm = 1/1,000,000mm) of ultra-low refractive index, with dimensions smaller than the wavelengths of visible rays of light. This nano-structured layer coupled with the sophisticated multiple layer coatings underneath, yields significant anti-reflection properties, efficiently reducing undesired flare and ghosting to an absolute minimum to deliver sharp, crisp images.
Compact and Stylish While covering a very wide range of focal lengths, this lens is remarkably compact and accepts 95mm filters. Its stylish design with signature Tamron tungsten silver finish and elegant brand ring incorporates a sturdy tripod mount to enhance both stability and ease of use.

Tamron Di lenses designed for digital SLR cameras.
Super Performance for 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 Tamronâs optical designers put their foremost priority on achieving superior performance parametersâthey 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.
Vibration Compensation Tamronâs Unique State-of-the-Art In-Lens Image Stabilization System: Handheld camera shake is the leading cause of blurry and unsharp pictures. Several leading companies now make lenses with built-in optical image-stabilization systems that sense the amplitude and direction of the shake and compensate by moving optical groups within the lens. Tamronâs exclusive new Vibration Compensation (VC) system thatâs built into the Tamron AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) Macro and the Tamron AF18-270mm F/3.5-6.3 Di-II VC LD Aspherical (IF) Macro lenses performs a similar function, but it executes it much more effectively due to its innovative breakthrough design.
While other image-stabilization systems can only correct the effects of camera shake in horizontal or vertical planes, Tamronâs VC system uses a tri-axial configuration that employs three pairs of driving coils and low-friction ball bearings placed around the shake-compensating optical group to produce, in effect, a free-floating shake compensator. This simple, elegant system is able to compensate for camera shake that occurs in diagonal direction as well as for up-and-down and side-to-side movements. Furthermore, due to its simple, low-friction design it is more responsive and durable than previous systems. The Tamron 28-300mm VC and 18-270mm VC lenses incorporate a highly sensitive and accurate gyro sensor for detecting even the slightest hand shake, and that,combined with a 32-bit RISC CPU and Tamronâs proprietary Algorithms and actuator, provides unequalled real-world performance. The bottom line: Tamron VC provides up to a 4-stop advantage in shooting sharp handheld pictures at slower shutter speeds along with a smooth, stable viewfinder image that is the envy of other shake-control systems. You can expect to see the VC feature built into more Tamron lenses in the future.
Ultrasonic Silent Drive Tamronâs USD works with the high-frequency ultrasonic vibrations that are produced by a ring called a âstatorâ. Energy from the vibrations is used to rotate an attached metallic ring known as the ârotorâ. Piezoelectric ceramic, an element 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 produced simple motion into energy known as âdeflective traveling wavesâ, which then moves around the circumference (rotation direction) of the ring.
With the USD, the friction between these deflective traveling waves created on the metallic surface of the stator and the surface of the rotor produce force, causing the rotor to rotate. The focusing ring lens, which is linked to the rotor, is thus moved, creating a fast and smooth auto-focus drive.
Low Dispersion (LD) Glass for Greater Lens Sharpness Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)
Rounded (Circular) Diaphragm Using a rounded (circular) diaphragm, this lens achieves spectacular blur effects. By distinctively blurring backgrounds and foregrounds this high-speed lens creates images that bring your subject into focus, thus to life.
