Tamron’s New 100-400mm Lens Weighs Only 1.1 kg

Tamron has today launched a new ultra-telephoto zoom lens: the Tamron 100-400mm f/4.5-6.3 Di VC USD. Made for full-frame cameras in Canon and Nikon mounts, the lens is said to deliver “fast and precise AF performance” with “consisntently powerful” vibration compensation.

The Vibration Compensation provides 4 stops of benefit thanks to its high-speed Dual MPU (Micro-Processing Unit) control system, signature of the latest Tamron lenses.

The lens has three low dispersion elements which work to reduce aberration, and it has has Tamron’s eBAND Coating for “superior” anti-reflection performance, in particular for when shooting backlit images. Tamron says that this low number of elements allows for “crisp images with excellent contrast.”

Weighing just 1.1 kg (39.3 oz), this lens will be welcome amongst wildlife photography circles. In fact, this makes it the lightest weight in the ultra-telephoto class, and it’s only 7.7 inches long. This has been achieved by crafting the lens from magnesium alloy in “key areas of the lens barrel” to ensure both a lightweight product with the necessary strength for work outdoors.

The new 100-400mm lens is “moisture-resistant” and has a fluorine coating for enhanced weather protection. Sealant has been applied to all of the moving parts and joints of the lens to resist moisture intruding on the equipment.

It has a minimum focus distance of 1.5 metres (59 inches), with a filter thread size of 67mm. There are 9 aperture blades, and it is constructed of 17 elements in 11 groups.

The lens will be available 16th November 2017. More information, and sample photos, is available on the Tamron website.
