>>4302282If you can afford the S5II, the Z6II is a similar camera for stills but cheaper because it's worse for video.
The only downside is there's a $250 adapter premium because the yakuza at sony told sigma they aren't allowed to release lenses for Nikon, only brands that aren't legitimate threats. But it's more than made up for by Nikon's very good S line lenses, and said adapter letting you use any sony lens.
