Scheduled for local release in May, the new Tamron 70-180mm f/2.8 Di III VXD lens features a compact and light-weight design with a 67mm filter diameter, which is the same as Tamron’s 17-28mm f/2.8 (Model A046) and the 28-75mm f/2.8 (Model A036) lenses. Featuring two of Tamron’s new VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanisms and a floating system, it produces clear and sharp images of both near and distant subjects and supports camera-specific features including Fast Hybrid AF and Eye AF. Other features include Moisture-Resistant Construction for added weather protection and Fluorine Coating for easy maintenance.
The optical design consists of 19 elements in 14 groups and includes six XLD (eXtra Low Dispersion) and LD (Low Dispersion) lens elements plus three GM (GlassMoulded Aspherical) and hybrid aspherical lens elements. BBAR-G2 (Broad-Band Anti-Reflection Generation 2) coating minimises ghosting and flare. This lens has a minimum focusing distance of 85 cm, with a maximum magnification ratio of 1:4.6 at the 180mm telephoto end. It weighs 810 grams. It is due to go on sale in May at an RRP of AU$2399.
