Tamron's second-generation 16-30mm F/2.8 Di III VXD G2 completes what reviewers have started calling the brand's fast-zoom "trinity" for full-frame mirrorless — a matched set of wide, standard, and telephoto f/2.8 zooms built to an internal-zoom design that keeps a constant length while zooming. This wide-angle entry adds a new VXD voice-coil autofocus motor for substantially faster focusing than its predecessor, along with full weather sealing.
At roughly 440 grams, it stays compact and lightweight for a fast ultra-wide zoom, delivering excellent center sharpness and strong corner performance that reviewers say holds up against Sony's own significantly pricier options. The value case is stark: where Sony's 16-35mm F2.8 GM II runs around $2,498, Tamron's G2 delivers comparable optical performance for well under half that price — the kind of gap that's made it one of the most recommended wide-angle zooms for Sony and Nikon shooters alike.
