Redefining the Sony G Series The farthest reaching Sony E-mount lens yet, the FE 400-800mm f/6.3-8 G OSS Lens from Sony is a super-telephoto powerhouse lens that's primed to be the dominant choice for capturing wildlife, nature, and sports. With this addition to the G Series, Sony continues to blur the lines between G and GM lenses, offering its users exceptional quality at a reduced cost. This lens features internal zoom for improved functionality as well as dual linear motors for smooth, quick AF performance. Optical SteadyShot stabilization includes three distinct modes, along with a focus limiter and three focus hold buttons for advanced control. For increased lens stability and sharper imagery, a fixed, rotating tripod foot is included on the lens. Unprecedented Range Not only is this the first Alpha zoom to reach 800mm, but its compatibility with 1.4x and 2x teleconverters extends the maximum focal length to 1120mm and 1600mm respectively, making this an elite choice for birding and wildlife as you'll be able to keep a safe distance from your subjects. Prioritizing Functionality & Usability Poised to outshine Sony's FE 200-600mm f/5.6-6.3 G OSS, this super-telephoto provides longer range and better overall lens performance while weighing just slightly more at 5.45 lb. Featuring a short rotational throw, this lens allows you to make swift focal adjustments while capturing. This zoom accepts screw-in filters on the front lens element, expanding your ability to create in various lighting conditions. Multiple function switches are built into the lens barrel that allow you to make rapid settings adjustments, including a switch for AF/MF, OSS, and focus limiting.
