{"product_id":"sony-fe-400mm-f4-5-gm-oss","title":"Sony FE 400mm F4.5 GM OSS","description":"\u003cp\u003e\u003cem\u003eBright 400mm reach in a lens made to move.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe Sony FE 400mm F4.5 GM OSS combines serious super-telephoto performance with a remarkably lightweight, handheld-friendly design. At just 2.2 pounds without its tripod mount, it gives wildlife, bird, sports, and action photographers the reach and subject separation of a 400mm prime without the size and weight normally associated with a professional super-telephoto lens.\u003c\/p\u003e\n\u003cp\u003eIts f\/4.5 maximum aperture supports fast shutter speeds and strong background separation, while G Master optics, responsive autofocus, and built-in Optical SteadyShot help deliver sharp, detailed images in demanding situations. Compatibility with Sony’s optional teleconverters extends the lens to 560mm or 800mm when additional reach is needed.\u003c\/p\u003e\n\u003ch3\u003eThe Looking Glass Take\u003c\/h3\u003e\n\u003cp\u003eThe FE 400mm F4.5 GM OSS may be one of the most practical super-telephoto primes Sony has made. It is fast enough for challenging light, long enough for birds, wildlife, field sports, and aviation, yet light enough to carry and use handheld for extended periods.\u003c\/p\u003e\n\u003cp\u003eCompared with a telephoto zoom, the fixed 400mm focal length gives up framing flexibility. In return, you get an f\/4.5 maximum aperture, G Master image quality, fast autofocus, and a lens that weighs less than many professional telephoto zooms. It also pairs especially well with Sony’s teleconverters, becoming a 560mm f\/6.3 or 800mm f\/9 without requiring a second large lens.\u003c\/p\u003e\n\u003cp\u003eFor photographers deciding between Sony’s new 400mm and 600mm primes, the 400mm is the more versatile choice. Its brighter aperture is useful in lower light and for fast action, while its native focal length makes it easier to locate and track moving subjects. The 600mm remains the stronger choice when maximum reach is the priority.\u003c\/p\u003e\n\u003ch3\u003eLightweight 400mm Performance\u003c\/h3\u003e\n\u003cp\u003eThe FE 400mm F4.5 GM OSS weighs only 994 grams, or 35.1 ounces, excluding its removable tripod mount. Its center of gravity is positioned closer to the camera body, improving balance while following birds in flight, panning with athletes, or holding a composition for an extended period.\u003c\/p\u003e\n\u003cp\u003eAt approximately 9.5 inches long, the lens fits more easily into a practical field kit than a traditional large-aperture super-telephoto. Internal focusing keeps its physical length and balance consistent as focus changes.\u003c\/p\u003e\n\u003ch3\u003eG Master Detail and Bokeh\u003c\/h3\u003e\n\u003cp\u003eThree Super ED elements and one ED element help suppress chromatic aberration and maintain fine detail across the frame. Sony’s Nano AR Coating II reduces flare and ghosting, preserving clarity and contrast when photographing backlit wildlife, sports, or outdoor subjects.\u003c\/p\u003e\n\u003cp\u003eAn 11-blade circular aperture and carefully controlled spherical aberration produce smooth, natural-looking bokeh. Combined with the 400mm focal length and f\/4.5 maximum aperture, this helps separate a subject from busy or distant backgrounds.\u003c\/p\u003e\n\u003ch3\u003eFast, Precise Autofocus\u003c\/h3\u003e\n\u003cp\u003eTwo XD Linear Motors provide fast, accurate, and quiet autofocus with responsive subject tracking. The lens is designed to follow unpredictable birds, wildlife, and athletes, including continuous shooting at up to 120 frames per second with the Sony α9 III.\u003c\/p\u003e\n\u003cp\u003eFull-time DMF allows immediate manual focus adjustment without first changing focus modes. A focus-range limiter can restrict focusing to distant subjects, reducing unnecessary focus travel when photographing action.\u003c\/p\u003e\n\u003ch3\u003eOptical SteadyShot Stabilization\u003c\/h3\u003e\n\u003cp\u003eBuilt-in Optical SteadyShot helps reduce camera shake and provides a steadier viewfinder image when shooting handheld at 400mm. Multiple stabilization modes support general photography, panning, and the tracking of fast or erratically moving subjects.\u003c\/p\u003e\n\u003cp\u003eCompatible Sony camera bodies can coordinate their in-body stabilization with the lens for improved handheld performance.\u003c\/p\u003e\n\u003ch3\u003eExtend Your Reach\u003c\/h3\u003e\n\u003cp\u003eThe lens is compatible with Sony’s optional 1.4x and 2.0x teleconverters:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eWith the 1.4x teleconverter: 560mm f\/6.3\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWith the 2.0x teleconverter: 800mm f\/9\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOn an APS-C Sony camera, the lens provides a field of view equivalent to 600mm on full frame before adding a teleconverter.\u003c\/p\u003e\n\u003ch3\u003eDesigned for Field Use\u003c\/h3\u003e\n\u003cp\u003eFour customizable focus-hold buttons are positioned around the lens barrel for easy access in horizontal or vertical orientations.

The dust- and moisture-resistant construction is designed for outdoor use, while a fluorine-coated front element helps resist moisture, fingerprints, and debris.\u003c\/p\u003e\n\u003cp\u003eThe lens also supports breathing compensation on compatible Sony camera bodies, making it useful for filmmakers who need long reach with smooth, controlled focus transitions.\u003c\/p\u003e\n\u003ch3\u003eKey
