Sharp Super-Telephoto Zoom, Tenacious AF
The first super-telephoto zoom in Sony’s flagship G Master series covers a versatile 100mm to 400mm 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 Zoom
A 100mm to 400mm zoom range is ideal for sports, wildlife, and similar subjects, with image quality and AF performance that support professional working needs.
Fast, Tenacious Autofocus
An optimal combination of double linear motor and DDSSM (Direct Drive SSM) drive systems achieves quick response, high accuracy, and tenacious tracking.
High Resolution and Fast AF at any Focal Length
Precision G Master optics ensure consistently high corner-to-corner resolution at any focusing distance throughout the lens’s zoom range.
Compact, Lightweight and Mobile
Innovative modular exterior construction and magnesium components reduce weight and size for improved portability and mobility.
Outstanding Shooting Versatility
A floating focus mechanism achieves a minimum focus distance of just 0.98 meters (3.22ft.) so you can track and shoot subjects at any distance with one lens.
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.
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.
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.
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 800mm (1200mm on an APS-C format body).2
Customisable 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.1
G Master series lenses take imaging and expression to previously unattainable levels with a stunning blend of extremely high resolution and softly dissolving background bokeh.
