G Master super-telephoto zoom
This 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 autofocus
The 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 length
A 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 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 falloff 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. (1. Nano AR coating / 2. Glass / 3. Transmitted light).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. Fine adjustment allows the feel of the lens to be matched to individual user needs.Clear, blur-free images without a tripod
Built-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 α series bodies that feature in-body stabilization.Outstanding shooting versatility
Floating 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 100mm.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.We offer in-store pickup as well as shipping
