It looks like Tamron is set to announce a second lens ahead of CP+ alongside the 70-210mm f/4 VC.
The second lens will be a Tamron 28-75mm f/2.8 Di III RXD, no further specifications have leaked at this time.
As noted on the forum, this is likely for full frame mirrorless cameras, which would be just Sony at the moment.
