eBAND and BBAR Coating.
Tamron?s proprietary eBAND (Extended Bandwidth & Angular-Dependency) Coating suppresses tangential reflections, while a new generation of BBAR (Broad-Band Anti-Reflection) Coating has been optimized for ultra-wide angles of view. Together, they effectively correct ghosting and flare, yielding vivid images of extraordinary clarity.
Vibration Compensation enhances photo opportunities.
Responding to the demand for a wide-angle lens suited for handheld shooting at slow shutter speeds, Tamron has created the world??s first F/2 .8 ultra-wide-angle zoom lens with image stabilization. The result is a lens able to capture sharp images even when shooting handheld under low light conditions.
Soft-focus backgrounds at wide-angle settings.
Thanks to its large F/2.8 aperture, this lens lets you soften the foreground or background to dramaticall”emphasize the subject. And with a minimum focusing distance of 0.28m over its entire focal-length range, it can capture wide-macro effects.
Fluorine coated front element.
Since its large diameter and prominent convex profile prevents deployment of a protective filter, the front element of this lens has a fluorine coating that repels water and dirt, and makes it much easier to remove smudges as well.
Resistant to the elements.
Moisture-resistant construction helps prevent moisture from penetrating the lens.
Ultrasonic Silent Drive for precise, and quiet autofocus.
The quiet high-torque USD motor ensures autofocusing with precision.
VC (Vibration Compensation) ??The VC Image Stabilizer delivers sharp and shake-free images, as well as a smooth viewfinder image.

eBAND Coating??Nano-structured lens coating to protect against unwanted reflection and ghosting.
USD (Ultrasonic Silent Drive)???Powerful ultrasonic motor for quick and dynamic subjects. It is extremely quiet, precise and allows manual control at any time.
LD (Low Dispersion) ??Lens element for greater image sharpness and the correction of chromatic aberration.
