Tamron has filed a new standard zoom lens patent in Japan. The application describes the Tamron 28-70mm f/3.5-5.6 VC lens designed for mirrorless cameras with full-frame image sensors.

Egami has spotted the file as the optic features a focal range between 28mm and 70mm along with a maximum aperture range of f/3.5-5.6. The standard zoom lens seems to feature built-in image stabilization technology.
