The first super-telephoto zoom in Sony's flagship G Master series covers a versatile 100 mm to 400 mm range. With extraordinary resolution and fast, precise autofocus it lets you capture distant action with outstanding quality and immediacy. In addition to world-class image quality, this fine lens offers the mobility, reliability, and operability that professional applications demand.g Master super-telephoto zoomThis top-performance G Master zoom lens covers a broad 100 mm to 400 mm focal length range that is ideal for sports, wildlife, and other subjects that require a long reach. It offers image quality and Af performance that will support professional fieldwork, tracking and capturing even fast-moving subjects with outstanding resolution and clarity.Fast, tenacious autofocusThe optimal 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 lengthA precision optical design ensures consistently high corner-to-corner resolution at any focusing distance throughout the lens's zoom range. The SEL100400GM 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 colorTwo 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 falloff in telephoto lenses. The result is exceptionally clear, well-defined images.Clarity and contrast in any lightSony'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. (1. Nano Ar coating / 2. Glass / 3. Transmitted light).Compact, lightweight and mobileMagnesium 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 adjustmentThis is the first 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. Fine adjustment allows the feel of the lens to be matched to individual user needs.Clear, blur-free images without a tripodBuilt-in Optical SteadyShot image stabilization makes it easier to capture blur-free images, particularly when shooting sports or other subjects that require fast stabilization response. Mode 2 stabilization facilitates dynamic panned shots. 5-axis stabilization becomes available when used with series bodies that feature in-body stabilization.Outstanding shooting versatilityFloating focus and high positioning precision have made it possible to achieve a minimum focus distance of just 3.22 feet (0.98 meters) with up to 0.35x magnification. You have a versatile 100 mm to 400 mm super-telephoto zoom range, plus outstanding close-up performance at 100 mm.
