Tamron patent for 10-24mm f/3.5-4.5 DiII VC USD lens

Another rather interesting Tamron patent. This time we have a Tamron 10-24mm f/3.5-4.5 DI II VC USD ultra wide-angle lens for APS-C DSLRs. The patent appears to point to the replacement for the Tamron SP AF 10-24mm f/3.5-4.5 DI II lens, which doesn’t feature image stabilisation.
