With an optical construction of 18 elements in 13 groups, inclusive of XGM (eXpanded Glass Molded Aspherical) element placed at the front group and several LD (Low Dispersion) glass elements in the system, aberrations such as geometrical distortion and lateral color are efficiently compensated for...

A very impressive lens, producing a high quality image wide open at all focal lengths. The lens appears to be a bit sharper at shorter focal lengths than at the long end, but the difference is minor.

The Tamron SP 15-30mm f/2.8 Di VC USD is the first fast ultrawide zoom lens for full frame cameras to offer built-in image stabilization. It's slightly wider than the closest offerings from Canon (16-35/2.8) and Nikon (17-35/2.8) but not quite as long when zoomed out.

This ultra-wide angle lens from Tamron sports a fast constant aperture of f/2.8 and as it is one of Tamron's 'SP' lenses, it sports rugged build quality and a dust and weather sealed construction.
