Tamron is rumored to announce a new 24-70mm f/2.8 Di VC USD G2 lens before the end of the year. The new version will be a replacement for the current Tamron 24-70mm f/2.8 model.
This is the next logical step after Tamron already refreshed their 70-200mm f/2.8 lens in early 2017.
Sigma, Tokina and Nikon also recently refreshed their 24-70mm f/2.8 lenses.
