The Sony FE 100-400mm F4.5-5.6 GM OSS is Sony's flagship super-telephoto zoom, a staple for wildlife, sports, and aviation shooters on E-mount. Reviewers consistently rate it as one of the best 100-400mm lenses made.

Sony 100-400mm F4.5 GM OSS Review | the Best 100-400 Ever!

Sharp, fast, and teleconverter-ready

Dustin Abbott and The-Digital-Picture describe excellent sharpness and contrast across the range — especially strong from 200mm to 400mm — backed by fast, reliable autofocus, effective Optical SteadyShot stabilization, and premium weather-sealed build. It pairs well with Sony's teleconverters to extend reach with minimal quality loss. In Dustin Abbott's review — featured above — he calls it among the best 100-400mm lenses ever.

Honest cons

  • Premium price. As a G Master super-telephoto, it's a significant investment.
  • Variable, relatively slow aperture. F4.5-5.6 limits low-light reach versus faster (and far pricier) primes.
  • Size and weight. It's a large lens that benefits from a monopod for long sessions.
  • Reach ceiling. 400mm may still be short for distant wildlife without a teleconverter.

Where this lens fits

  • Wildlife and bird photographers who need reach, sharpness, and reliable tracking AF.
  • Sports and aviation shooters wanting a versatile, durable telephoto zoom.
  • Sony shooters who plan to add a 1.4x or 2x teleconverter for extra reach.
  • Not budget buyers, those needing a fast constant aperture, or anyone wanting a compact travel lens.
