Zoom Into The World Of Telephoto. The World's Smallest & Lightest Telephoto Zoom Lens For Sony Full-Frame E-Mount Mirrorless Cameras. 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. A High-Resolution Telephoto Zoom Lens For Sony E-Mount Mirrorless Cameras That Is Powerful, Portable, & Fun. To make the 300mm telephoto focal length more fun and accessible, Tamron focused intently on designing a telephoto zoom lens that's both small and lightweight. Turning the conventional concept of a telephoto lens on its head, the 70-300mm F4.5-6.3 is only 148mm (5.8 in) in length with a maximum diameter of 77mm and a weight of just 545g (19.2 oz). Achieves The Ultimate Combination Of Lightweight & Outstanding Optical Performance. The 70-300mm F4.5-6.3 zoom's optical design was refined via thorough simulations utilizing the latest technologies. With high priority on reduced size and weight, Tamron selected the aperture of F6.3 for the telephoto end to achieve a slim lens barrel and outstanding lightness. High Performance Autofocus System Means You'll Own Every Shot. The AF drive on the 70-300mm F4.5-6.3 includes an RXD motor unit to help you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that precisely detects the position of the lens enables high-speed and accurate AF, which is ideal when shooting continually moving subjects or recording video. Features A telephoto zoom so compact you want to carry around everyday Tamron has adopted a dedicated design for mirrorless cameras and achieved a compact size once again by fixing the aperture at F6.3 at the telephoto end. The maximum diameter is 77mm. Measuring just 148mm (5.8 in) and weighing a mere 545g (19.2 oz), this 70-300mm F4.5-6.3 is the world's smallest and lightest telephoto zoom lens for full-frame mirrorless cameras. Compatible with Sony's popular E-mount cameras, it has been developed with the concept of enabling photographers to more easily experience the universe of full-scale, full-frame 300mm telephoto photography. In addition, the AF drive system incorporates the exceptionally quiet RXD (Rapid eXtra-silent stepping Drive) stepping motor. Because this lens is compatible with Sony camera features, including in body image stabilization and Eye AF, you can enjoy comfortable, high-speed, high precision telephoto photography, even handheld. Experience the excitement of bringing distant subjects closer as well as the perspective flattering characteristics achieved by full-scale telephoto photography more easily than ever before. For landscapes, sports, birds and wildlife as well as closer subjects such as portraits and street scenes, this lens expands the range of telephoto photography. Superior optical performance and supreme lightweight portability Pursuing lightweight design as a top priority, Tamron has created a compact 70-300mm F4.5-6.3 zoom lens that makes 300mm telephoto shooting easy and fun. The superb optical design is based on a rigorous simulation process using state-of-the-art design technologies. As a result, Tamron has successfully struck a balance between extreme lightness (545g / 19.2 oz) and compactness, incorporating a slim lens barrel with a maximum diameter of 77mm without sacrificing high image quality. The optical design includes 15 elements in 10 groups, with an LD (Low Dispersion) lens element precisely arranged to suppress axial chromatic and other aberrations that are likely to happen with telephoto zoom lenses. At 300mm, a commonly used telephoto zoom focal length, the design delivers excellent resolution from edge-to-edge. Overall, the efficient optical construction (which also contributes to its light weight) plus Tamron's BBAR (Broad-Band Anti-Reflection) Coating with its well-established reputation for anti-reflection properties, combine to enable the photographer to capture extremely clear, crisp images across the entire zoom range.
