Tamron announced today that it’s developing a new Tamron 100-400mm f/4.5-6.3 Di VC USD lens. Weighing it at just 39.3 ounces (~1.11kg), the lens will be the lightest in its class (the ultra-telephoto zoom lens category).
The lens has an “advanced optical design,” including 3 low dispersion lens elements which give “greater aberration reduction.” It uses magnesium in key areas of the barrel, which improves weight reduction, strength, and portability.
It also comes with Tamron’s original eBAND Coating, which Tamron says provides superior anti-reflection performance to reduce ghosting.
“The Model A035 delivers fast and precise autofocus performance and consistently powerful vibration compensation benefits,” said Tamron. “This is thanks to the high-speed Dual MPU control system found in the latest Tamron lenses.”
The new lens will be fully compatible with Tamron’s 1.4x teleconverter, as well as the Tamron TAP-in Console. There will be an optional accessory of an Arca Swiss compatible tripod mount, too.
“This combination of features and optional accessories join to create a lens that photographers everywhere will enjoy using in various shooting situations,” said Tamron.
Other features and specs include a minimum focus distance of 59 inches (~1.5m), a maximum magnification ratio of 1:3.6, moisture resistance, and a fluorine coating for weather protection.
The Tamron 100-400mm f/4.5-6.3 Di VC USD lens lens will be launched at the end of 2017, available in both Canon and Nikon mounts.
