Product Highlights: [ Amazon US – Pre-order Price: $4,299.99 ] Sony FE 100-400mm F4.5 GM OSS (SEL100400MCW.UC) | Constant F4.5 | 11-blade Aperture | 1,840g
Sony just released the 2026 FE 100-400mm F4.5 GM OSS (SEL100400MCW.UC) super-telephoto zoom in the USA. It’s listed on Amazon for $4,299.99. This is a G Master lens built for things like wildlife, sports, and news photography where you need a lot of reach without losing light. Check it out on Amazon.com here.
Product Summary: The big deal with the SEL100400MC is the constant F4.5 aperture. Most zooms this long get “darker” as you zoom in, but this one stays at F4.5 from 100mm all the way to 400mm. It’s also pretty light for its class at 1,840g. It uses an internal zoom design, so the lens doesn’t physically get longer when you zoom. That helps keep the balance steady if you’re using a tripod or gimbal.

Quick Links
Better AF and Tracking
Sony put four XD Linear Motors in this lens. They say it’s up to 3x faster at focusing than older designs. If you’re using a fast camera like the Alpha 9 III, it can track moving subjects at up to 120 fps. It’s also designed to stop “focus breathing,” so it should work well for video too.
Build and Handling
It’s made with a magnesium alloy body to keep the weight down. Since it’s an inner-zoom lens, the center of gravity doesn’t shift much when you’re tracking a bird or a car.
There’s a function ring on the barrel that you can set to different things—like switching between Full Frame and APS-C mode or recalling a specific focus point. It’s also got a zoom smoothness switch so you can decide how much resistance the zoom ring has.
