Superb corner-to-corner image quality from an ultra-wide-angle zoom
The new 15-30mm F/2.8 full-frame ultra-wide-angle zoom is a worthy addition to the Tamron SP (Super Performance) lens series, renowned for its highest standards. Thanks to the development of its unique XGM (eXpanded Glass Molded Aspherical) element, the high-performance zoom lens offers the same performance as would two fixed focal length lenses of 15mm and 30mm.
The unique XGM element responsible for this unprecedented achievement effectively controls aberrations and enhances sharpness.
Функции и характеристики
Because the large diameter and prominent convex profile of the front element does not allow the use of a protective filter, the front element of the lens has a fluorine coating. The coating repels water and dirt, and also makes it much easier to remove smudges.
The combination of a large diameter XGM (eXpanded Glass Molded Aspherical) with several LD elements in the first lens group of the 18-element, 13-group optical design effectively controls distortion and chromatic aberrations that typically affect wide-angle lenses.
A new generation of BBAR (Broad-Band Anti-Reflection) Coating has been optimized for ultra-wide angles of view. Together with Tamron’s proprietary eBAND (Extended Bandwidth & Angular-Dependency) Coating which suppresses tangential reflections, they effectively correct ghosting and flare, yielding vivid images of extraordinary clarity.
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
Thanks to its large F/2.8 aperture, this lens lets you soften the foreground or background to dramatically emphasize the subject. It can also capture wide-macro effects with its minimum focus distance of 0.28m over the entire focal-length range.
The quiet high-torque USD motor ensures autofocusing with precision.
