What are the alternatives to the sigma 300 600mm f 4 dg os sports?

The site doesn't have a full list of other lenses to compare against the Sigma 300-600mm f/4, so I can only point you in a few directions.

The closest alternative I can name is the Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports. It covers a much wider range, from 60mm to 600mm, but it's slower at the long end, so you'll need more light or higher ISO.

For reach, I'd start with the reach guide. A 100-400mm zoom on APS-C or Micro Four Thirds gives a lot of reach in a much lighter kit. On full frame, a 200-600mm or 150-600mm zoom is the usual choice. A 600mm f/4 prime is wonderful, but it's very heavy and very expensive.

If budget matters, read my picks and buying used. Long lenses hold their value, but used prices can be a real saving.
