Sony FE 100-400mm f4.5 GM OSS Zoom

Sony FE 100-400mm f4.5 GM OSS Zoom
1/4
    Product Details

    The Sony FE 100-400mm f/4.5 GM OSS is a constant-aperture supertelephoto zoom built to the exacting standards of Sony's G Master series. Designed for wildlife, sports, and action photographers who refuse to compromise on optical performance or speed, this second-generation 100-400mm brings a completely redesigned internal zoom mechanism, dramatically faster autofocus, and upgraded optical stabilisation — all in a weather-sealed, carry-friendly package weighing under 2kg. Whether you're tracking birds in flight, freezing fast-moving athletes, or reaching for distant subjects on location, the 100-400mm f/4.5 GM delivers with authority.

    Key Highlights

    • 100–400mm constant f/4.5 maximum aperture supertelephoto zoom
    • Internal zoom mechanism for constant balance and barrel length
    • 4x XD Linear motors (2 per focus group) for class-leading AF speed
    • 3x faster focus speed vs. original 100-400mm GM
    • 50% improvement in AF tracking performance
    • Compatible with Sony 1.4x and 2x teleconverters
    • Optical SteadyShot (OSS) image stabilisation with selectable modes
    • 28 elements in 20 groups including ED, Super ED, XA, and ED XA elements
    • 11-blade circular aperture for smooth, natural bokeh
    • 95mm front filter thread + 40.5mm drop-in filter slot
    • Minimum focus distance: 0.64m (wide end), 0.24x maximum magnification
    • Dust and moisture resistant throughout, fluorine-coated front element
    • Built-in carry grip on tripod foot with security lock slot
    • Dimensions: 119.8 x 328mm | Weight: 1,840g

    Class-Leading Autofocus

    Four XD (extreme dynamic) Linear motors — two dedicated to each of the two focus groups — deliver the precise, rapid, and tenacious autofocus performance that advanced sports and wildlife photographers demand. Compared to the original 100-400mm f/4.5-5.6 GM, this new lens achieves a 3x improvement in focus speed and a 50% improvement in tracking performance, translating directly into a higher keeper rate after every shoot. Critically, this improved AF performance holds up in the most demanding conditions, including 120fps capture and focus acquisition during zoom actuation.

    Versatility Without Compromise

    The internal zoom design maintains a constant barrel length and centre of gravity throughout the zoom range, making the lens far more comfortable to handle and more predictable to balance on a gimbal or monopod. A broad, quarter-turn zoom throw lets you shift rapidly between 100mm and 400mm for quick subject acquisition and framing. Full compatibility with Sony's 1.4x and 2x teleconverters extends the reach further still, giving you an effective 560mm or 800mm when the situation demands it.

    Exceptional Optics

    The optical formula comprises 28 elements in 20 groups, incorporating Extra-low Dispersion (ED), Super ED, extreme aspherical (XA), and ED XA elements working in concert to suppress chromatic aberration, maintain edge-to-edge sharpness, and deliver the colour accuracy and contrast that define G Master glass. The 11-blade circular aperture produces smooth, pleasing bokeh that isolates subjects beautifully at any focal length. A fluorine coating on the front element repels water, dust, and fingerprints for reliable performance in the field.

    Portable and Built to Last

    Weighing in at 1,840g — under 2kg — the 100-400mm f/4.5 GM is genuinely field-portable for a lens of this reach and aperture. A comfortable carrying grip is integrated into the tripod foot for easy one-handed transport, and a security lock slot provides extra peace of mind during remote or unattended shooting setups. Full dust and moisture sealing at every button, ring, and joint ensures the lens can handle demanding outdoor conditions with confidence. A customisable function ring and four assignable focus hold buttons round out a control layout designed for intuitive, distraction-free operation.
