* Length, entire length and weight values given are for the Nikon mount.
*1: Length is the distance between the mount face and the tip of the lens.
*2: Entire length is the distance between the tip of the lens and the tip of the protrusion.
*3: This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.
*4: The Sony mount does not include VC, as Sony digital SLR bodies include image stabilization functionality.
High resolution with beautiful blur effects – Two XLD (Extra Low Dispersion) glass elements(*1) made from specialized, high-grade glass and one LD (Low Dispersion) element are combined to thoroughly correct aberration. Moreover, the latest optical design and rounded diaphragm(*2) deliver a spectacular blur effect. This macro lens maintains sharp focus on the subject together with soft natural blurring of foregrounds and backgrounds to achieve a richer, deeper feel in the image.
New eBAND (Extended Bandwidth & Angular-Dependency) Coating
This new coating technique developed by Tamron deploys a nano-structured layer (1nm = 1/1,000,000mm) of ultra-low refractive index, with dimensions smaller than the wavelengths of visible rays of light. This nano-structured layer coupled with the sophisticated multiple layer coatings underneath, yields significant anti-reflection properties, efficiently reducing undesired flare and ghosting to an absolute minimum to deliver sharp, crisp images.
VC (Vibration Compensation)(*3)
This macro lens is equipped with the VC mechanism that delivers sharp and vivid viewfinder images. Even in low-light situations, camera shake is reduced to enable stress-free hand-held photography.
1:1 Maximum magnification ratio
The maximum magnification ratio of the new 90mm Macro is 1:1, which lets you reproduce a life-size image of the subject on the image sensor. This lens is suited to close-up photography of small objects, enabling the photographer to capture the minute world that otherwise would be missed when viewed just by the naked eye.
The lens incorporates the IF system, which focuses by moving only the internal lens group. The overall length of the lens therefore does not change when focusing, thus ensuring a broad working distance. As a result, comfortable macro shooting is enabled.
Moisture-resistant construction helps prevent moisture from penetrating the lens.
USD（Ultrasonic Silent Drive）
The quiet high-torque USD motor ensures a speedy and accurate autofocus response.
Full-time manual focus
Fine focus adjustments using manual focus can be made during autofocus shooting, without the need to change focus mode.
*2 This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.
*3 From 3m, the benefits of VC gradually decrease as the focus distance becomes closer.
