Tamron SP 70-300mm f/4-5.6 Di VC USD Full Frame Lens For Canon - AFA005C-700
The Tamron SP designation is reserved for lenses developed with special emphasis on extraordinary photographic performance. Engineers are free to innovate in an uncommon atmosphere where optical performance comes before price, resulting in lenses that satisfy the demands of discerning photographers.
Fast becoming a benchmark for this category, the SP 70-300mm F/4-5.6 Di VC is an ideal choice for a two-zoom system—complimenting a wide-to-moderate-tele zoom perfectly. Delivering class-leading sharpness, brilliant color and striking contrast, discriminative APS-C and full-frame digital SLR photographers alike are quick to laud its performance. The first lens to feature Tamron's USD (Ultrasonic Silent Drive) auto-focus drive mechanism and VC (Vibration Compensation)* image stabilization, these proprietary technologies are teamed with XLD (Extra Low Dispersion) and LD (Low Dispersion) glass in a 17 element, 12 group formula. APS-C-sensor photographers will enjoy extreme telephoto subject magnification, with a resulting picture angle range approximating a 109-465mm lens on a 35mm film or full-frame DSLR. Sharpness, enhanced by Tamron's exclusive tri-axial VC image stabilization is amazing. Combating blur from camera shake, Tamron VC enables shooting handheld at as many as four shutter speeds slower than would be possible otherwise. Full-time manual focus makes fine tuning easy.
- 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 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.
- Tamron's 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. Tamron's exclusive new Vibration Compensation (VC) system that's 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.
- Ultrasonic 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, 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 'deflective traveling waves', 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.
- Extra Low Dispersion
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.
- Full Time Manual Focus
makes fine tuning easy
All Tamron lenses have high autofocus precision and are designed to capture subjects easily in almost any situation, yet sometimes a photographer wants to fine tune and make adjustments on the fly. The integration of full time manual focus offers just that: instead of fumbling with switches, photographers can switch from autofocus 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.
