Best telephoto lens for the sony a9 ii?

The a9 II is a fast full-frame sports body, so it pairs best with a long lens that can keep up. If you shoot sport or distant birds and can carry the weight, my pick is the Sigma 300-600mm f/4 DG OS Sports. An f/4 aperture across that whole range is unusual.

If you want something lighter, these are the other strong options from the catalogue:

• Sony FE 100-400mm f/4.5 GM OSS, a compact all-round telephoto zoom.
• Sony FE 200-600mm f/5.6-6.3 G OSS, a native zoom with plenty of reach.
• Sigma 150-600mm f/5-6.3 DG DN OS Sports, for reach at a lower aperture.
