Does the Sony FE 100-400mm GM OSS have image stabilization?

Can the Sony FE 100-400mm GM OSS be used with teleconverters?

Yes, it is fully compatible with the SEL14TC and SEL20TC teleconverters for a 1.4x or 2x increase in focal length, reaching a maximum of 800mm. On an APS-C format body, this extends to 1,200mm.

Is 400mm enough reach for wildlife photography?

The 100mm to 400mm range is well suited to sports, wildlife, and distant action, and can be extended further with compatible teleconverters for a maximum focal length of 800mm on full-frame or 1,200mm on APS-C bodies. This gives you added reach for more distant or smaller subjects.

What autofocus system does the Sony FE 100-400mm GM OSS use?

It uses an optimal combination of double linear motor and Direct Drive SSM (DDSSM) drive systems, a first of its kind. Precision sensors provide real-time feedback for extremely high positioning accuracy, allowing the camera body's AF system to perform at its best.

Is the Sony FE 100-400mm GM OSS weather sealed?

The overall design is dust and moisture resistant for reliable operation in challenging environments, so you can shoot with confidence in light rain or windy conditions. The front element also features a fluorine coating that helps prevent dirt and fingerprints from sticking. Note that it is not guaranteed to be 100% dust- and moisture-proof.

What is the zoom torque adjustment feature on the Sony FE 100-400mm GM OSS?
