One of the lenses on the Tamron teaser I posted about few days ago will be a new SP 85mm f/1.8 Di VC USD and will be available in Nikon, Canon and Sony mounts (via Digicame-info). There is already a patent for a Tamron SP 85mm f/1.4 Di VC USD lens. The second lens that will be announced on February 22nd will probably be wide angle, since Tamron already has 35mm and 45mm SP lenses.
Update: the second Tamron lens will be a SP 90mm f/2.8 Di MACRO 1: 1 VC USD (Model F017) for Canon, Nikon and Sony mounts (no VC for Sony).
