Tamron 90mm f/2.8 SP Di MACRO 1:1 VC USD Lens
features Vibration Compensation image-stabilization technology for limiting camera shake blur, and an Ultrasonic Silent Drive Motor for fast, smooth and quiet autofocus. Lens mounts are available to fit Canon, Nikon and Sony cameras
A continuous manual focus mechanism provides precise manual focus, especially important with this lens’ 1:1 macro capability. And an Internal Focusing system means the front lens elements do not rotate and the lens does not change length when focusing, also important for macro shooting. In addition to macro capability, this 90mm lens is also considered to be an ideal lens for portraiture.
Two extra-low dispersion elements and one low dispersion element reduce chromatic aberration and make for sharp, high resolution images. Newly developed eBAND hybrid lens coating combines conventional multi-coating with a layer of nano-structured coating for particularly uniform light transmission and minimal reflection. This reduces flares and ghosting in your images.
An extra large and ridged focus ring and moisture resistant construction give muscle to this optically impressive lens.
VC (Vibration Compensation) is Tamron’s proprietary image stabilization mechanism which reduces the effects of camera shake to deliver sharp images in low light and at slower shutter speeds. It is a newly developed three coil system that employs a lighter moving coil mechanism which contributes to its improved performance and overall compact design.
USD (Ultrasonic Silent Drive) Motor is the power for a fast and quiet autofocus drive that works in harmony with continuous manual focus mechanism.
The IF (Internal Focus) system focuses by moving only the internal lens group, rather than the front lens elements- therefore, the overall length of the lens does not change when focusing.
1:1 maximum reproduction ratio and 11.8″ (0.3 m) minimum focusing distance provide sharp close-up performance.
