Sony states that autofocus is up to approximately 3x faster, with approximately 50% improved subject tracking when mounted on the Alpha 9 III under Sony test conditions. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 data-end=\"1506\" data-start=\"1476\" data-section-id=\"1qy7z7z\"\u003eLooking Glass Photo’s Take:\u003c\/h2\u003e\n\u003cp data-end=\"1733\" data-start=\"1508\"\u003eThe big story here is not simply that Sony made a new 100-400mm lens.

That changes the character of the lens.\u003c\/p\u003e\n\u003cp data-end=\"2177\" data-start=\"1735\"\u003eThe original FE 100-400mm F4.5-5.6 GM OSS has been a trusted choice for wildlife, sports, travel, and outdoor photography because it offers excellent reach in a relatively manageable package. The new FE 100-400mm F4.5 GM OSS is more ambitious. It is larger, heavier, and more expensive, but it gives photographers a brighter long-end aperture, steadier balance while zooming, faster AF performance, and more professional control in the field.\u003c\/p\u003e\n\u003cp data-end=\"2457\" data-start=\"2179\"\u003eFor casual travel or hiking, the older 100-400mm may still make more sense. For serious birding, wildlife, field sports, motorsports, outdoor events, and high-end Sony Alpha work, the new f\/4.5 version is the one built to keep up with faster cameras and more demanding subjects.\u003c\/p\u003e\n\u003ch2 data-end=\"2523\" data-start=\"2459\" data-section-id=\"n7tzbb\"\u003eWhy photographers will like the Sony FE 100-400mm F4.5 GM OSS\u003c\/h2\u003e\n\u003cul data-end=\"4618\" data-start=\"2525\"\u003e\n\u003cli data-end=\"2722\" data-start=\"2525\" data-section-id=\"1ggnu2i\"\u003e\n\u003cstrong data-end=\"2580\" data-start=\"2527\"\u003eConstant f\/4.5 aperture throughout the zoom range\u003c\/strong\u003e — Maintains the same maximum aperture from 100mm to 400mm, helping avoid exposure shifts while zooming. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2973\" data-start=\"2724\" data-section-id=\"1qkwbja\"\u003e\n\u003cstrong data-end=\"2753\" data-start=\"2726\"\u003eG Master optical design\u003c\/strong\u003e — Uses a newly developed ED XA element, one XA element, two Super ED elements, and three ED glass elements to help control chromatic and spherical aberrations across the zoom range. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"3261\" data-start=\"2975\" data-section-id=\"17m4heb\"\u003e\n\u003cstrong data-end=\"3006\" data-start=\"2977\"\u003eFast autofocus for action\u003c\/strong\u003e — Four custom-optimized XD Linear Motors, a floating focus mechanism, and updated AF algorithms deliver autofocus speeds up to approximately 3x faster than the FE 100-400mm F4.5-5.6 GM OSS under Sony test conditions. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"3463\" data-start=\"3263\" data-section-id=\"1csnf7u\"\u003e\n\u003cstrong data-end=\"3294\" data-start=\"3265\"\u003eImproved subject tracking\u003c\/strong\u003e — Sony states approximately 50% improved subject tracking compared with the previous 100-400mm GM when mounted on the Alpha 9 III. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"3689\" data-start=\"3465\" data-section-id=\"d50nwd\"\u003e\n\u003cstrong data-end=\"3491\" data-start=\"3467\"\u003eInternal zoom design\u003c\/strong\u003e — The lens maintains a constant length and stable center of gravity throughout the zoom range, making it easier to track fast subjects and keep framing steady. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"3882\" data-start=\"3691\" data-section-id=\"ouclt8\"\u003e\n\u003cstrong data-end=\"3729\" data-start=\"3693\"\u003eOptical SteadyShot stabilization\u003c\/strong\u003e — Built-in stabilization supports Active Mode and coordinated stabilization control with compatible camera bodies. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"4079\" data-start=\"3884\" data-section-id=\"ljal1s\"\u003e\n\u003cstrong data-end=\"3917\" data-start=\"3886\"\u003eProfessional field controls\u003c\/strong\u003e — Four focus hold buttons and a dedicated function ring give photographers more ways to customize operation while shooting. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"4330\" data-start=\"4081\" data-section-id=\"h38gj3\"\u003e\n\u003cstrong data-end=\"4114\" data-start=\"4083\"\u003eTeleconverter compatibility\u003c\/strong\u003e — Compatible with Sony’s 1.4x and 2x teleconverters, giving photographers the ability to reach up to 800mm, or up to 1200mm equivalent in APS-C mode with the 2x teleconverter. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"4618\" data-start=\"4332\" data-section-id=\"1eij3qc\"\u003e\n\u003cstrong data-end=\"4360\" data-start=\"4334\"\u003eBuilt for outdoor work\u003c\/strong\u003e — Dust- and moisture-resistant design, plus a fluorine coating on the front element, helps the lens hold up in challenging field conditions.
