Sony FE 600mm f/4 GM OSS (SEL600F40GM)
A no-compromise 600mm f/4 G Master with OSS, aimed at long-reach wildlife and birding and ready to pair with teleconverters for 840mm or 1200mm reach. The 3040g weight underlines that this is a specialist tool for working pros only. Like its 400mm sibling, it uses 40.5mm drop-in rear filters rather than screw-on front filters.
