SP 15-30mm F/2.8 Di VC USD - Nikon
Tamron aims for the highest standards with the SP (Super Performance) lens series – and the 15-30mm F/2.8 full-frame ultra-wide-angle zoom is a worthy addition.
This high-performance zoom lens equals the performance of fixed focal length lenses from 15mm to 30mm, an unprecedented achievement made possible by the development of its unique XGM (eXpanded Glass Molded Aspherical) lens element that effectively controls aberrations and enhances sharpness. The Tamron 15-30mm is the first zoom* to combine such a wide range of coverage, a fast f/2.8 aperture and image stabilisation.
<b>Superior new coating for wide-angle image quality</b>
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 optimised for ultra-wide angles of view. Together, they effectively correct ghosting and flare, yielding vivid images of extraordinary clarity.
<b>Vibration Compensation enhances photo opportunities</b>
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 stabilisation. The result is a lens able to capture sharp images even when shooting handheld under low light conditions.
<b>Soft-focus backgrounds at wide-angle settings</b>
The large f/2.8 aperture lets you soften the foreground or background to dramatically emphasise the subject. A minimum focusing distance of 0.28m over its entire range of focal lengths allows wide-macro effects.
<b>Fluorine coated front element</b>
As the large, convex front element cannot be protected by a filter, it has been given a fluorine coating that repels water and dirt, and makes it much easier to remove smudges as well.
<b>Resistant to the elements</b>
Moisture-resistant construction helps prevent moisture from penetrating the lens.
<b>Ultrasonic Silent Drive for precise, quiet autofocus</b>
The quiet high-torque USD motor ensures autofocusing with precision.
