Tamron has announced the development of a 70-300mm F4.5-6.3 lens that it designed for full-frame mirrorless cameras. Tamron is touting it as being the world’s smallest and lightest 70-300mm zoom lens. It is 14.8cm (5.8 in) long, and it weighs in at 545g (19.2 oz).
The lens features a moisture-resistant construction and it shares the same 67mm filter diameter common to all members of Tamron’s lens series for full-frame mirrorless cameras. The lens can take advantage of in-camera features, including Sony’s Fast Hybrid AF and Eye AF.
The 70-300mm F4.5-6.3 is being targeted as a low-cost, lightweight telephoto lens that is suitable for landscape, sports, and other athletic events, wildlife, and portraits.
Tamron already makes an SP 70-300mm f/4-5.6 Di VC USD Telephoto Zoom Lens for Canon and Nikon DSLR cameras. This new lens will probably take some of its design cues from the older lens.
The lens is scheduled to start shipping sometime in the northern hemisphere fall. There is currently no indication of pricing.
