Tamron SKU: AFF004C-700 | Helix SKU: TRAFF004C700
Tamron's classic 90mm Macro lens is reborn with Vibration Compensation (VC) image stabilization(1), 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 (2) 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.
(1) The Sony mount does not include the VC image stabilization functionality, as Sony digital SLR camera bodies include image stabilization functionality. Consequently, the name of the Sony mount lens, SP 90mm F/2.8 Di MACRO 1:1 USD, does not include the VC description.
(2) This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.
