Tamron 70-300mm F/4.5-6.3 Di III RXD for Full-Frame and APS-C Sony Mirrorless Cameras (Model A047)

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. It achieves the world's smallest size and lightest weight, coming in at 5.8 in. long with a maximum diameter of 77mm, and weighing just 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) unit, a high-speed precision AF drive system that is remarkably quiet. The 70-300mm 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. Designed for full-frame, the lens is at home on APS-C mirrorless cameras and provides a 105-450mm equivalent field-of-view.

High quality images with beautiful, dreamy bokeh

The lens is made up of 15 elements in 10 groups with an appropriate arrangement of Low Dispersion (LD) lens elements. Aberrations such as axial chromatic aberration have been corrected. The 300mm end, which receives particularly frequent use in a telephoto zoom, provides excellent high-resolution performance from the center of the image all the way to the corners. Stunning bokeh (intentional background blur qualities) are another remarkable feature of this new les.

Superb Auto Focus keeps it sharp and quiet

The auto focus drive incorporates an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit. RXD uses an actuator that is able to precisely control the rotational angle of the motor allowing it to drive the focusing lens with out passing through a reduction gear. The addition of a sensor that detects the position of the lens to a high degree of accuracy enables high-speed and precise auto focus, which allows you to maintain razor-sharp focus when shooting continual moving subjects or filling video. The lens is also remarkably quiet, eliminating the concerns of a drive sounds being picked up while shooting video.

Tamron offers a unified system of lenses with 67mm filter size

Combine the 70-300mm F4.5-6.3 with other members of Tamron's lineup of 67mm filter size lenses and cover an even wider range of scenes. The shared 67mm filter size enables efficiency in filter use. So the same polarizer filters or other filters and lens caps can be shared between models.
