Commack, NY—Tamron USA, Inc., announced the development of the ultra-telephoto Tamron 100-400mm f/4.5-6.3 Di VC USD zoom lens for full-frame DSLR cameras. The advanced optical design of model A035 includes three LD (low dispersion) lens elements for greater aberration reduction. In addition, Tamron’s original eBAND (extended bandwidth & angular-dependency) antireflection coating aids in eliminating flare and ghosting, to provides clear images.
Weighing in at 39.3 ounces, Tamron claims the new lens is currently the lightest weight in its class for 35mm full-frame DSLR cameras. It also features magnesium material in key areas of the lens barrel “to improve weight reduction, strength and portability.”
Model A035 is engineered to deliver fast and precise autofocus performance and consistent VC (vibration compensation) benefits. This is due to the high-speed dual MPU (micro-processing unit) control system found in Tamron’s latest lenses.
Moreover, the new ultra-telephoto lens is fully compatible with Tamron’s 1.4x teleconverter and the Tamron TAP-in Console. This optional accessory enables lens customizations for focus adjustments, VC mechanism adjustments and other functions.
An Arca Swiss-compatible tripod mount also is available as an optional accessory. “This combination of features and optional accessories join to create a lens that photographers everywhere will enjoy using in various shooting situations, including low-light conditions that require handheld operation as well as those where convenient attachment to a tripod is preferred,” Tamron announced.

The lens’s three LD elements effectively compensate for axial chromatic and other aberrations. These aberrations are a potential issue for ultra-telephoto lenses. The ultra-telephoto zoom also has a MOD (minimum object distance) of 59 inches and a maximum magnification ratio of 1:3.6.
The Tamron 100–400mm f/4.5–6.3 Di VC USD zoom lens will be released by the end of 2017 in Canon and Nikon mounts. tamron-usa.com
