<b>A new masterwork lens in the 90mm Macro, which features beautiful blur effects and sharp images while inheriting the Tamron tradition</b>
Tamron's classic 90mm Macro lens is reborn with Vibration Compensation (VC) image stabilization, Ultrasonic Silent Drive (USD) motor, and new advanced optical design. It uses two Extra Low Dispersion (XLD) glass elements made from specialized, high-grade glass and one Low Dispersion (LD) element, which are combined to ensure sharp images by thoroughly correcting any aberration. In addition, its new advanced optical design and a rounded diaphragm have enabled this lens to achieve spectacular blur effects. The new eBAND (Extended Bandwidth & Angular-Dependency) Coating yields significant anti-reflection properties, efficiently reducing undesired flare and ghosting to an absolute minimum to deliver sharp, crisp images. The lens also boasts improved operability enabled by the Internal Focusing (IF) system, which focuses without protruding the lens group, as well as full-time manual focus that enables fine focus adjustments. The lens also comes in a moisture-resistant construction that helps prevent moisture from penetrating the lens.
