What are the alternatives to the sony fe 600mm f 4 gm oss?

The closest alternative I cover is the Sony FE 600mm f/6.3 GM OSS. It's also a 600mm prime for full frame, but at about a kilogram it's far easier to hand-hold for wildlife. You give up a stop of light, so it's slower in dim woods or at dusk.

If you want to save more money and weight, I'd look at long zooms instead. My guide to wildlife and sport suggests a 100-400mm-class zoom on an APS-C body for starting out, or a 200-600mm or 150-600mm zoom on full frame for serious bird work. Smaller sensors also give you more reach for the money, as explained in sensor sizes. Buying used makes any of these much cheaper, so check buying used before you commit.
