Tamron 15-30mm F/2.8 Di VC USD SP
Superb corner-to-corner image quality from an ultra-wide-angle zoom.
Tamron 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 wide-angle lenses.

*This circular diaphragm stays almost perfectly circular up to two stops down from maximum aperture.
**Length & Weight are based on figures for the Canon-mount & the Nikon-mount lens.
***Length is the distance from the front tip of the lens to the lens mount face.
****The Sony mount does not include the VC image stabilization functionality, as the body of the Sony digital SLR camera includes image stabilization functionality.
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 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.
Super Performance – Tamron’s Super Performance series delivers a range of lenses that meet the highest standards.
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.
Internal Focusing (IF) System – The extension length of the lens does not change during focussing and the close focussing distance is significantly reduced across the entire focusing range.
Zoom Lock (ZL) Mechanism – Protects against undesired extension of the lens barrel.
