Our take on the SIGMA 100-400mm F5-6.3 DG DN OS C for Sony E

A full-frame super-telephoto zoom for Sony E-mount cameras, built to be light and compact for its reach. At about 40 oz and 7.8 inches long, it is far easier to carry than a 400mm prime or a 150-600mm zoom, and the optical stabilization helps handheld shooting at the long end. Autofocus is a stepping motor, so it is quick and quiet for stills and video but not the fastest for fast action. Reviewers rate the sharpness and value highly; the main trade-offs are the dim f/6.3 maximum aperture at 400mm and the extending barrel.

What reviewers say

  • 4.6 / 522 ratings

Owners and reviewers rate it 4.6 out of 5 and call it one of the best value super-telephoto zooms for Sony E-mount. They praise the light weight, stabilization and sharpness for the class, and accept the slow aperture as the price of that portability.

What people mention
  • WeightPraisedOwners say it is easy to carry all day, far lighter than 150-600mm zooms.
  • StabilizationPraisedReviewers report steady handheld shots at 400mm thanks to the OS system.
  • SharpnessPraisedImages are described as sharp across most of the zoom range, especially stopped down.
  • ApertureCriticisedThe f/6.3 maximum at 400mm is called limiting for dim light and fast action.
  • Zoom barrelMixedThe extending barrel is seen as a dust risk but also keeps the lens compact.
  • AutofocusMixedFocus is quiet and accurate but slower than premium telephotos for fast subjects.

Questions and answers

Is the Sigma 100-400mm good for wildlife?
Yes, in good light. The 400mm reach and light weight suit hiking and birding, but the f/6.3 aperture means you need daylight or high ISO for fast movement.
Does it work on APS-C Sony cameras?
Yes. On APS-C it gives a 150-600mm equivalent field of view, which makes it a strong budget wildlife option.
Does it have image stabilization?
Yes, it has optical stabilization. On Sony bodies with in-body stabilization the two work together for steadier handheld shots.
How close can it focus?
About 5.25 ft at all focal lengths, which is close enough for large insects, flowers and detail shots at 400mm.
Is a tripod collar included?
No, the tripod collar is sold separately. The lens is light enough to handhold, but a collar helps balance it on a tripod.
How does it compare with the Sony 100-400mm GM?
The Sony is faster, sharper at the edges and focuses quicker, but it is much heavier and far more expensive. The Sigma trades some speed and build for portability and value.
