The 70-300mm F/4.5-6.3 Di III RXD (Model A047) for Sony E-mount and Nikon Z 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 5.9 in. long with a maximum diameter of 77mm, and weighing just 20.5 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. With the Nikon Z-mount version, users can employ
the dedicated TAMRON Lens Utility software. This feature enables users to easily update the
lens to the latest firmware themselves, without going through the camera . On the firmware
information screen, users can confirm that their lens has the latest version and perform an
update if newer firmware is available. Designed for full-frame, the lens is at home on APS-C
mirrorless cameras and provides a 105-450mm equivalent field-of-view.
