Tamron Developing 90mm Macro

SP 90mm F/2.8 Di VC USD for Canon, Nikon and Sony mounts

[1] VC (Vibration Compensation) is Tamron's proprietary image stabilization mechanism.
[2] USD (Ultrasonic Silent Drive) is Tamron's proprietary ultrasonic motor drive.
[3] The Sony mount does not include VC, as Sony digital SLR bodies include image stabilization functionality. The Sony lens is designated as "SP 70-200mm F/2.8 Di USD"
[4] This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.
[5] The XLD (Extra Low Dispersion) glass is made from specialized high-grade glass, which offers greater chromatic aberration correction properties than LD (Low Dispersion) elements.
[6] The eBAND (Extended Bandwidth & Angular-Dependency) Coating is a new nanotechnology-based coating technique developed by Tamron to reduce unwanted reflection.
[7] From 3m, the benefits of VC (Vibration Compensation) gradually decrease as the focus distance becomes closer.
[8] Length, entire length and weight values given are for the Nikon mount.
[9] Entire length is the distance between the tip of the lens and the tip of the protrusion.
[10] Length, entire length and weight values given are for the Nikon mount.
[11] Coupler system refers to a system that uses a shaft to harness the AF motor built into the camera body to operate the lens.

About Tamron
Tamron is a recognized leader in the manufacture of precision optics offering a broad selection of meticulously engineered interchangeable lenses for professional photographers and photo enthusiasts. Founded in 1950, Tamron's passion for innovation brought forth the ground-breaking development of mass-produced hybrid Aspherical elements, giving way to enormously popular compact, wide-range zoom lenses. Dynamic research and development , committed to advanced optical engineering, has produced a stream of award-winning Tamron lenses and defined the All-in-One zoom lens category, exemplified by 2010's 18-270mm Di II VC PZD. Astonishingly compact and lightweight, this 15X zoom features proprietary VC (Vibration Compensation) technology, effectively counteracting image-degrading blur caused by camera shake along with a fast, quiet PZD (Piezo Drive) autofocus mechanism. Tamron lenses deliver a superb fusion of performance and value, enabling today's high-resolution digital SLR cameras to perform at their peak. Tamron's lenses have received numerous prestigious awards from around the world, including 14 EISA (European Imaging & Sound Association) awards, 7 of which were awarded consecutively since 2006.
