Fast, tenacious autofocus
A floating focus mechanism driven by a combination of double linear motor and DDSSM (Direct Drive SSM) drive systems is the first of its kind. It also implements precision sensors that provide real-time feedback for extremely high positioning accuracy, allowing the body’s AF system to perform at its best.
High resolution at any focal length
A precision optical design ensures consistently high corner-to-corner resolution at any focusing distance throughout the lens’s zoom range. The Sony FE 100-400mm G Master lens not only delivers stunning images of distant subjects at super-telephoto focal lengths, it offers equally high performance when shooting nearby subjects as well.
Natural rendering and color
Two ED (Extra-low Dispersion) glass elements and one Super ED glass element strategically deployed in an advanced optical design effectively suppress axial chromatic aberration that is often a cause of resolution fall-off in telephoto lenses. The result is exceptionally clear, well-defined images.
Clarity and contrast in any light
Sony’s Nano AR Coating suppresses spurious reflections that can cause flare and ghosting in backlit and other challenging lighting situations, for consistently high contrast and clarity. Reduced flare, particularly when shooting in bright outdoor conditions, means greater framing and composing flexibility.
Compact, lightweight, and mobile
Magnesium alloy components and other refinements contribute to high durability as well as class-leading size and weight reductions that not only mean greater mobility, but improved manageability with lightweight bodies for easier, more stable handheld shooting.
Zoom torque adjustment
This is the first α lens to include a zoom smoothness adjuster that provides mechanical control of zoom ring torque. Set a lower torque for fast zooming, or increase torque when slow, stable zooming is required.
Fluorine coated front element
The lens’s front element features a fluorine coating that helps to prevent dirt and fingerprints from sticking, and makes it easier to wipe dirt and fingerprints away if they do become attached to the lens surface. This can be a significant advantage for outdoor shooting.
