$1,930.00
Sony's G Master super-telephoto zoom built for working professionals.
The FE 100-400mm f/4.5-5.6 GM OSS covers the focal range that sports and wildlife shooters live in, and Sony engineered it to perform at the demanding end of that work. The 22-element, 16-group optical formula delivers consistent corner-to-corner resolution across the entire zoom range, not just at the sweet spot. A floating focus mechanism using dual linear motors and Direct Drive SSM keeps subjects locked in fast-changing situations, and the minimum focus distance of 3.22 ft (0.98 m) means you're not stuck reaching for a second lens when a subject closes in.
Built-in Optical SteadyShot handles the stabilization duties handheld, with a Mode 2 option specifically tuned for panning shots. Pair it with an Alpha body that has in-body stabilization and you get 5-axis correction. The 77mm front element carries a fluorine coating to shed fingerprints and moisture during outdoor work, and the dust and moisture-resistant construction holds up in field conditions. At 1,395 g and 205 mm long, it's not a light kit, but for a full-frame super-telephoto zoom that performs at this level, the tradeoff is well understood by anyone who's shot at 400mm on a deadline.
Who It's For
Sports photographers working sidelines or tracks will find the fast dual-motor AF and 100-400mm range a reliable combination for tracking athletes in motion. Wildlife shooters benefit from the 3.22 ft minimum focus distance, which keeps the lens useful when animals approach closer than expected. Birders shooting handheld in changing light get real help from the OSS system, particularly in panning situations. Safari and travel photographers who need reach without committing to a prime will appreciate the zoom flexibility across a range that covers most field scenarios on a single native E-mount lens.

FAQ
- What autofocus system does this lens use?
- Dual linear motors paired with Direct Drive SSM (DDSSM) deliver fast response and tenacious tracking. The floating focus mechanism also allows minimum focus distance of 0.98 m, so you're not locked out when subjects move closer.
- How much does optical stabilization help at 400mm?
- Built-in Optical SteadyShot handles handheld work at the long end. When paired with Alpha bodies that have in-body stabilization, you get full 5-axis correction. Mode 2 tuning is specifically configured for panning shots.
- Is this lens weather-sealed for field work?
- Dust and moisture-resistant construction holds up in challenging outdoor conditions. The 77mm front element has fluorine coating to shed fingerprints and moisture, making it practical for extended shoots in light rain or windy conditions.
- What's the optical design, and does it stay sharp across the zoom range?
- 22 elements in 16 groups with one Super ED element and two ED elements deliver consistent corner-to-corner resolution across the entire 100-400mm range, not just at certain focal lengths. G Master optics ensure that sharpness doesn't degrade as you zoom.
- How much does this lens weigh and how long is it?
- At 1,395 g (49.21 oz) and 205 mm long, it's substantial but manageable for a full-frame super-telephoto zoom. The magnesium construction keeps weight reasonable for the focal range and performance level.
- Can I use a tripod mount with this lens?
- Yes, it includes a removable tripod mount that attaches and detaches quickly so you can switch between handheld and tripod work without unscrewing the lens. A lock mechanism prevents accidental removal.
- What filter size does this lens accept?
- 77mm filters thread directly onto the front element, making it easy to add polarizers or neutral density filters for your shooting conditions.
