This ultra-wide-angle zoom lens delivers superior optical performance with excellent image quality. This is only possible with high brightness, rounded aperture blades and thanks to a new optical system specifically designed for Sony mirrorless cameras. The Tamron 17-28mm stimulates expressive and creative photography in a variety of scenarios, thanks in part to a unique minimum focusing distance of only 19cm in wide-angle and 26 cm in tele-mode. The overall length does not change when zooming in or when focusing, and therefor creating a stable, well-balanced operation and excellent portability. In addition, the Tamron 17-28mm has a filter size of only 67mm, which is very small for an ultra-wide-angle zoom lens. The usability and versatility inherent in compact Full-Frame mirrorless cameras is enhanced by the compact length and light weight of the Tamron 17-28mm, which is only 99mm and 420 gram.
