Last month, Tamron announced the development of a new 35-150mm f/2-2.8 Di III VXD zoom lens for Sony E-Mount. They claimed it to be the “world’s first mirrorless zoom lens with a maximum wide-open aperture of f/2”. Of course, it’s not and came with caveats, which seems to be the way with Sony stuff. Along with this lens, Tamron also announced the development of a 28-75mm f/2.8 zoom.
Both lenses are expected to be announced on October 28th, according to Nokishita. But that’s not all they said. They also posted all of the images and complete specs brochures for both lenses.
