• 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 
  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 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
• 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)
• 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
• 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
• 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 100 mm
• Zoom torque adjustment 
  This is the first ƒ¿ 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 ƒ¿ series bodies that feature in-body stabilization
• Teleconverters for extra reach 
  SEL100400GM is fully compatible with the high-performance SEL14TC and SEL20TC teleconverters for a 1.4x or 2x increase in focal length, respectively. That's a maximum focal length of 800 mm (1,200 mm on an APS-C format body)
• Customizable focus hold button 
  Conveniently located focus hold buttons provide focus hold control even during continuous AF operation. They can also be customized from a camera menu that allows them to be assigned to a variety of different functions
• Removable tripod mount 
  A removable tripod mount allows quick attachment to or removal from a tripod so the user can easily switch between tripod and handheld shooting. The mount can also be removed for convenient transport and storage. A lock mechanism prevents accidental removal
• Pro lens hood features
  An access window that can be opened or closed as required allows easy access for polarizing filter operation, and a hood lock switch prevents accidental detachment or rotation of the lens hood while shooting or moving around
• 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
• High reliability in harsh conditions
  The overall design of this lens is dust and moisture resistant for extra protection and reliable operation in challenging environments. Shoot with confidence in light rain or windy conditions
