Touted as the most compact lens in its class, the Tamron SP 70-200mm f/2.8 Di VC USD includes four low-dispersion elements and an extra low dispersion lens.
It measures 196.7×85.8mm (length x diameter).
The 90mm f/2.8 Di Macro 1:1 VC USD is a redesigned version of Tamron’s original 90mm macro lens, incorporating Vibration Compensation and an Ultrasonic Silent Drive.
It features Extended Bandwith & Angular-Dependency coating (eBAND) which aims to improve anti-reflection performance, to help reduce flare and ghosting.
Both lenses will be available in Canon, Sony and Nikon mounts.
