Sony G Master 100-400mm f/4.5-5.6 OSS, the E-mount super-telephoto benchmark.

The G Master 100-400mm covers a 100-400mm range with 22 elements in 16 groups, and the optical formula is built around corner-to-corner resolution at every focal length, not just the center frame. A floating focus mechanism using dual linear motors and Direct Drive SSM delivers fast, accurate tracking on subjects that don't cooperate, birds mid-flight, athletes at full sprint, wildlife that won't wait. The minimum focusing distance of 3.22 ft (0.98 m) gives you a tighter working range than most super-telephotos of this class.

Optical SteadyShot image stabilization includes a Mode 2 setting specifically tuned for panning, and when paired with Sony Alpha bodies that have in-body stabilization, you get full 5-axis compensation. The 77mm front element is fluorine coated to shed fingerprints and moisture, which matters when you're shooting in the field for hours. Dust and moisture resistance throughout the barrel backs that up. At 1395g, this is a telephoto zoom you can carry all day without a cart, and the removable tripod collar lets you switch between handheld and mounted shooting without rethinking your setup.

Teleconverter compatibility extends the reach further, and the customizable focus hold buttons can be remapped to any function your shooting style demands. For Sony E-mount shooters who need serious reach without a dedicated prime, this lens has been the professional answer for years.

Who It's For

Wildlife photographers working unpredictable distances will appreciate the 3.22 ft minimum focus distance and fast dual-motor AF system, which tracks erratic subjects without hunting. Sports shooters benefit from Mode 2 OSS, built for panning shots that freeze lateral movement. Birders and nature photographers who hike to their locations will value the 1395g weight against the optical output, since it's light enough to carry hand-held but sharp enough to satisfy high-resolution bodies. Video operators covering live events can use the smooth OSS response and remappable focus hold buttons for controlled, run-and-gun telephoto work.

FAQ

What autofocus system does this lens use?
Dual linear motors paired with Direct Drive SSM (DDSSM) deliver fast, accurate tracking on moving subjects. The floating focus mechanism maintains corner-to-corner resolution throughout the zoom range, and minimum focusing distance of 0.98m lets you work closer than most super-telephotos in this class.
How effective is the image stabilization for handheld shooting?
Optical SteadyShot (OSS) with Mode 2 panning control handles most handheld work. Pair it with Sony Alpha bodies that have in-body stabilization and you get full 5-axis compensation, which stacks stabilization for significantly better handheld performance at 400mm.
Can you use teleconverters with this lens?
Yes, the FE 100-400mm is compatible with Sony teleconverters, which extend your effective reach beyond 400mm. Autofocus performance will vary depending on which teleconverter and camera body you're using.
How much does this lens weigh and is it practical for all-day shooting?
At 1,395g (49.21 oz), it's portable enough for handheld all-day work. The removable tripod collar lets you switch between handheld and mounted shooting without adjusting your entire rig, and the compact modular construction keeps size reasonable for a 100-400mm zoom.
What coating does the front element have?
The 77mm front element is fluorine coated to shed fingerprints and moisture during field work. The entire barrel is dust and moisture resistant, which matters when you're shooting in light rain or windy conditions without babying the gear.
Is this lens sharp across the entire frame at all focal lengths?
G Master optics deliver corner-to-corner resolution at every focal length, not just the center. The 22-element, 16-group optical design with one Super ED element and two ED elements is built specifically for consistent sharpness edge-to-edge throughout the zoom range.
Can you customize the focus hold buttons?
Yes, the focus hold buttons are remappable through your camera menu to any function your shooting style demands, which gives you control over AF behavior during continuous tracking.
