Tamron SP 15-30mm F2.8 Di VC USD Nikon- mount lens review: Tempting option?

Introduction Specifications and FeaturesAnnounced at the tail-end of 2014, the Tamron SP 15-30mm f2.8 Di VC USD is not, as you might expect, intended for APS-C format models; instead, it’s an ultra-wide, full-frame, high-speed zoom targeting the 16-35mm f2.8 equivalent offerings from Canon, and Nikon. That makes it rather niche, but it has a number of attractive features, including a silent sonic-type motor, optical stabilization (what Tamron calls Vibration Compensation or VC), anti-ghosting nano-type (eBAND) and hydrophobic fluorine coatings. It also has a circular 9-bladed aperture, rendering rounded highlights and smooth transitions to areas of differential focus.Tamron
