Tamron has filed a new patent for a 16-70mm f/4 full frame mirrorless lens. The 16-70mm is a very common lens in the APS-C world, but for full-frame cameras this focal length is quite unusual. However, this patented 16-70mm F4 has a wide wide-angle side and a wide telephoto side, and it seems to be very convenient because it is a lens that can completely cover two wide-angle zoom and standard zoom with one lens. If you can achieve reasonably good optical performance with this spec, it will be one of the popular Tamron lenses.
