Superior, class leading imaging performance using an innovative XGM lens element
With an optical construction consisting of 18 elements in 13 groups, including, for the first time, an XGM (eXpanded Glass Molded Aspherical) lens element placed in the front group, and several Molded-Glass Aspherical elements and LD (Low Dispersion) elements used throughout the optical system, aberrations such as geometrical distortion and lateral color are efficiently corrected enabling the zoom lens to deliver outstanding image quality throughout its entire zoom range from corner to corner.
Enhanced sharpness with exclusive VC image stabilization when shooting handheld in low light or at night
In response to popular demand, Tamron has created the world’s first F/2.8 ultra-wide- angle zoom lens with VC (Vibration Compensation). The VC allows shooting at slow shutter speeds and in low light conditions, and effectively compensates for minor camera shake, whilst maintaining class leading optimal performance.
eBAND Coating provides superior anti-reflection properties
In addition to further optimizing Tamron’s acclaimed BBAR (Broad-Band Anti-Reflection) Coating, the eBAND (Extended Bandwidth & Angular-Dependency) Coating has also been employed in this lens. This combination offers superior anti-reflection properties especially important in ultra-wide-angle lenses which are particularly susceptible to flare and ghosting due to their wide angle of view, and provides superior quality and crystal-clear images by minimizing unwanted light reaching the sensor.
Fascinating background “bokeh” throughout the wide-angle range due to its fast constant F/2.8 aperture
Utilizing its shallow depth of field at F/2.8, it enables users to capture beautiful bokeh effects even at wide coverage angles. Its advanced optical formula and 9-bladed circular diaphragm are designed with defocused photography in mind - perfect for creating images where subjects stand out from their natural, blended backgrounds.
Proven fluorine coating utilizing Tamron's industrial lens expertise is used on the front element
Fluorine coating, with an established track record in Tamron's industrial lenses, such as those used in automotive cameras, has been applied to the front element. It repels water and dirt, and makes it easier to remove smudges.
Lens hood designed to prevent light from striking lens at all focal lengths
This unique lens hood provides effective shading of the front lens surface over the entire zoom range to minimize flare. It utilizes the unique characteristics of the optical system in which the front lens group recedes as you zoom in from 15 mm to 30 mm.
Double-hood structure provides additional strength
A double-hood structure has been incorporated into the lens design to improve the durability of the zoom mechanism.
