The Sony FE 400mm f/2.8 GM OSS is ideal for shooting events like the Olympics and it even looks like there might be a teleconverter on this lens if you look closely. It’s also very likely that the photographer is using the Sony a9 so the combination here is probably the Sony FE 400mm f/2.8 GM OSS + 1.4xTC on a Sony a9 with grip and I bet Sony would like to have a bunch of these in photographers hands by the 2020 Tokyo Olympics. Fujifilm also has high-end end telephoto glass coming in time for Tokyo along with a Sony a9 like camera, the Fujifilm X-T3, so maybe both companies will make a big push at the 2020 Olympics.
