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.
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.
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.
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.
Moisture-resistant construction helps prevent moisture from penetrating the lens.
