Sigma 60-600mm F4.5-6.3 DG DN OS | Sports

Reviewers found it consistently sharp from 60mm to about 400mm, with a mild drop at 600mm f/6.3 that mostly recovers by f/8. Considering the 10x range, chromatic aberration and distortion are well controlled, and it compares well with the older DSLR 60-600.

The HLA autofocus is a clear step up from Sigma's earlier stepping-motor telephotos and tracks birds in flight on modern Sony bodies. The criticisms are weight, the 105mm filter size, and a long barrel extension at 600mm. Sigma's teleconverters are not available for the Sony E version.

Owners use it for wildlife trips, air shows and sports sidelines, and value going from a wide environmental frame to full 600mm without swapping bodies. The stabilisation and the close-focus ability at 200mm come up often in positive reviews.

The main complaints are its weight for handheld shooting, the front-heavy balance when extended, and f/6.3 in poor light. Some owners say the push-pull action takes practice and that the hood is very large.
