85 out of 100 medium confidence 24 reviews

The Sigma 300–600mm f/4 DG OS Sports lens receives overwhelmingly positive feedback for its exceptional sharpness, fast autofocus, and versatility as a zoom that rivals prime lenses.

A few reviewers experienced initial shipping delays or a zoom lock-up issue, but the latter was quickly resolved under warranty.

Pros
  • Exceptional sharpness wide open
  • Fast and accurate autofocus
  • Versatile zoom range replacing multiple primes
  • Excellent value for money
  • Smooth and creamy bokeh
Cons
