Superb corner-to-corner image quality from an ultra-wide-angle zoom.
aims for the highest standards with the SP (Super Performance) lens
series. And the new 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. In addition, the 15-30mm is the
first zoom to combine such a wide range of coverage, a fast F/2.8
aperture, and to offer image stabilization, further proof of Tamron's
commitment to innovation and excellence.
XGM lens element for exquisite images.
A large diameter XGM (eXpanded Glass Molded
Aspherical) lens element is placed in the first lens
group of a system that also includes several LD (Low
Dispersion) elements in its 18-element, 13-group
optical design. This combination
effectively controls distortion and
chromatic aberrations that typically affect
eBAND and BBAR Coating.
Tamronʼs 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
dramatically emphasize the subject.
And with a minimum focusing
distance of 0.28m over its entire
focal-length range, it can capture
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.
Ultrasonic Silent Drive for precise, and quiet autofocus.
