We now know that Tamron’s new stabilized 85mm f/1.8 Di VC USD lens retails for $749 and will be available by the end of this month for Canon and Nikon DSLRs. A Sony A-mount option is also coming along shortly but won’t feature the internal image stabilization since A-mount cameras offer sensor-based stabilization.
You can pre-order the new Tamron SP 85mm f/1.8 Di VC USD lens for each of the mount options here at B&H Photo.
