The world’s smallest and lightest1 telephoto zoom lens for Sony full-frame E-mount mirrorless cameras

The 70-300mm F/4.5-6.3 Di III RXD (Model A047) for Sony full-frame E-mount mirrorless cameras is a telephoto zoom lens designed and created so photographers of all skill levels can enjoy high quality images comfortably. Tamron’s new 70-300mm F4.5-6.3 covers a broad telephoto zoom range yet is the world’s smallest size and lightest weight, coming in at 148mm (5.8 in) long with a maximum diameter of 77mm, and weighing just 545g (19.2 oz). With special emphasis on resolving power, Tamron has deployed special lens elements appropriately arranged to correct chromatic aberration, generally very strong in a telephoto lens, as well as other aberrations. Users can enjoy high-resolution images combined with the stunning bokeh qualities that are achievable only with a telephoto lens. The lens also incorporates the RXD (Rapid eXtra-silent stepping Drive) stepping motor unit, a high-speed precision AF drive system that is remarkably quiet. Tamron’s Moisture-Resistant Construction provides extra protection, while various features that are built into Sony mirrorless cameras, including “Eye AF,” are supported. The 70-300mm F4.5-6.3 is a versatile lens for photographing landscapes, sports and other action, pets and wildlife and more. The lens also demonstrates its potential for portrait shooting, casual snapshots and scenarios that require you to be mobile and shoot handheld, like sporting events. The apparent image compression and the close-up effects characteristic of telephoto lenses naturally amplify photographic expression. Zooming in on distant objects and making them appear closer is one of the joys of telephoto shooting. This zoom lens provides an entryway into that new world.
