Tamron announced the development of a 17-50mm f/4 Di III VXD (Model A068) fixed aperture standard zoom lens for full-frame Sony E-mount cameras. This internal zoom lens will surely be a good alternative to lenses such as the Sony Vario-Tessar T FE 16-35mm F4 ZA OSS, and even the faster Sony FE 16-35mm F2.8 GM.
