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
Floating focus with 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.

Zoom torque adjustment
This is the first a 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.

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.

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.

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)
