I actually don’t buy the argument that people move to Sony for their native lenses. Sure, some people do in fact make the full switch. But most people I know who move to Sony can’t afford a new body AND all new lenses, so they are adapting their current lenses to Sony. Most often they are coming from Canon. But lots of people adapt various other lenses.
Again, this is where I think Nikon has gone wrong in not marketing the advantages of sticking with Nikon glass and using the adapter. Some people will balk. Some people may have a one off lens that won’t AF with the adapter (??♀️). But the vast majority of the people transitioning from Nikon dSLR to Nikon mirrorless can have a seamless transition with little cost other than a new body. There are plenty of legacy lenses for Nikon to take their time engineering new lenses.
I moved away from Sony because of the price of their native lenses - and the relentless non-stop annual new shiny upgrade in order to get continued support for firmware issues.
