At the same time, it also announced an updated version of its 28-75mm lens (also for Sony full frame) the Tamron 28-75mm f/2.8 Di III VXD G2. Both lenses are "expected" to launch this year.

While mirrorless f/2 zoom lenses aren't new, with the ridiculously good Canon RF 28-70mm f/2L USM being the first one to hit the market, the Tamron 35-150mm f/2-2.8 Di III VXD is the first one to hit Sony systems – and possesses a much more all-purpose focal length and form factor.
Ideal as a walkabout lens, and especially for shooting travel photography, the 35-150mm will undoubtedly prove popular for those seeking a one-size-fits-all optic – particularly with its minimum object distance of 0.33m at the wide end.
Tamron promises that its VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism "features a very high-speed and high-precision autofocus for a fast-aperture lens."
The G2 retains the compact size (and 67mm filter thread) of its predecessor, but boasts a new and improved optical formula to "based on a design that has been revamped to enhance imaging performance and its features are compatible with the latest model digital cameras that offer increased resolution."
It likewise features Tamron's VXD autofocus drive for fast and precise AF. It also has a minimum object distance of 0.18m at the wide end, with a maximum magnification ratio of 1:2.7, again making it a go-to optic for creative close-up shooting.
Again, Tamron says that it expects both lenses to ship in 2021 – though release dates are obviously a bit of a moving target, between pandemic issues and the global component and chip shortages.
