A while back, Tamron stated that they were working on a killer wide angle zoom lens in the form of the 15-30mm f2.8 lens. Today, the company has made it official. So what’s so special about this lens? Well according to reports, it’s supposed to be able to work with 50MP sensors. But that hasn’t proven yet. What we indeed do know is that it has an f2.8 constant aperture throughout the range.
The Tamron 15-30mm f2.8 Di VC USD lens has 18 elements in 13 groups, an XGM lens element at the front (eXpanded Glass Molded Aspherical), an eBAND coating to prevent reflections, nine aperture blades, and a fluorine coating on the front element.
