This super-telephoto zoom lens delivers sharp images thanks to its uncompromising optical design and high-speed, high-precision AF drive. This zoom lens covers the 400mm super-telephoto range required for sports and wildlife photography. It not only delivers sharp images, but also boasts a high-speed, high-precision AF drive that ensures you never miss a decisive moment, further expanding your shooting horizons. Designed with mobility, reliability, and ease of use in mind, it meets the demands of professionals across a wide range of photography genres. A new optical design that meets the high standards of G Master achieves high resolution performance across the entire zoom and focus range. Super ED (extra-low dispersion) glass and ED glass are strategically placed to suppress axial chromatic aberration, which often occurs with telephoto lenses, and magnification chromatic aberration, which can lead to reduced resolution at the edges of the image. Furthermore, Sony's proprietary Nano AR coating minimizes unwanted light reflection, making it less susceptible to sunlight even when shooting outdoors, ensuring clear images all the way to the edges. Beautiful bokeh, a G Master lens. The optical design, which focuses on bokeh, and optimally adjusts spherical aberration during the manufacturing process, delivers smooth, beautiful bokeh that complements sharp images. The floating mechanism achieves a minimum focusing distance of 0.98m and a maximum magnification of 0.35x. Sharp images of close subjects. The floating mechanism effectively corrects aberrations when focusing at close distances. Despite being an ultra-telephoto zoom lens, it achieves a minimum focusing distance of 0.98m and a maximum magnification of 0.35x. Its excellent close-up shooting capabilities enable sharp depictions of both distant and nearby subjects. The lens features a direct-drive SSM (DDSSM) front motor and a double linear motor rear motor for quiet, high-precision focus lens operation. This lens not only delivers excellent close-up shooting capabilities, but also boasts high-speed, highly responsive AF. The double linear motor in the main motor enables quick focus lens operation, enabling precise focusing on even the most fleeting movements, perfect for sports and wildlife photography. Weighing approximately 1,395g (excluding tripod mount), the lightweight E-mount body and excellent balance support stable shooting. The use of magnesium alloy parts and innovative design features make this lens the lightest ultra-telephoto zoom lens in its class, weighing approximately 1,395g (excluding tripod mount). This lightweight design meets the expectations of many ultra-telephoto lens users. This maximizes the benefits of compact, lightweight E-mount cameras, reducing portability and enabling stable shooting when handheld shooting is required, such as for wildlife photography, by easily balancing the camera with a lightweight E-mount camera.
Superior operability for field work: The camera is equipped with a focus hold button that locks the focus even in continuous AF mode. The focus hold button can be assigned a desired function via body customization. Other features include a focus range limiter that pre-defines the focus range for quick focusing, a hood with a retractable operation window for easy access to PL filters, and a hood lock switch that prevents the hood from coming off or rotating during shooting or transport, providing excellent operability for field work.
The camera is equipped with optical image stabilization (OIS) for convenient handheld shooting. MODE 2 is also available for effective panning shots. The built-in OIS ensures sharp subject capture even when handheld. It quickly and precisely corrects camera shake, even in sports photography where the framing is constantly changing. MODE 2, convenient for panning shots, is also available, providing a dynamic sense of movement. Furthermore, when mounted on an α body equipped with 5-axis in-body image stabilization, it compensates for camera shake in all five directions, providing powerful support for your photography. The zoom operation feel adjustment ring allows you to adjust the resistance of the zoom ring. By rotating the adjustment ring, you can mechanically adjust the rotational torque of the zoom ring. Whether you want quick zoom movements or want to prevent the zoom position from changing unexpectedly, you can achieve the operation feel you desire depending on the application and scene. The detachable tripod mount allows you to quickly switch from a tripod-mounted lens to handheld shooting. It features a revolving mechanism that allows for easy changes to portrait and landscape compositions, and a locking function to prevent the lens from falling off. Furthermore, the tripod mount's protrusions can be detached, improving storage and portability.
