The Sony FE 100-400mm F4.5-5.6 GM OSS lens is the first superzoom in SONY's top-of-the-line G Master series. The 100 to 400mm range makes it a versatile focal length for shooting nature or sporting events. Dual linear and direct drive ultrasonic motors (Direct Drive SSM) provide lightning-fast response and precision when focusing and tracking the subject.

Speed and quality
Lens focusing is handled by a combination of a dual linear motor and DDSSM (Direct Drive SSM) drive, the first of its kind ever. Thanks to this combination, the lens promises an instantaneous response that you can use, for example, when capturing action shots. For user adjustment, there is the option of adjusting the resistance of the zoom ring. The lens construction consists of 22 members in 16 groups. One Super ED member, providing extremely low dispersion and effectively suppressing axial chromatic aberration, a common cause of quality degradation in telephoto lenses, and two ED members, providing low image dispersion

New lens design
With a new lens body made from magnesium alloy components and other improvements, it contributes to the high durability in this lens segment. The weight of only 1395 g points to comfortable carrying, greater mobility and also pleasant handling with a lightweight body and more stable handheld shooting. Overall, the construction is dust and moisture resistant, giving the lens the ability to be used in harsh environments.Thefluorite coating on the front lens is also an advantage, which prevents dust and dirt from collecting

Features and customisation options
For natural use, this lens has the ability to adjust the zoom ring torque and is the first Sony lens to feature this function. So you can set a lower torque to achieve a fast zoom, or conversely, increase it to achieve a slower and more stable zoom. There are functional focus lock buttons on the lens body. They can also be set for other functions from the camera menu. To extend the zoom range, you can use the SEL14TC and SEL20TC teleconverters.
