If I lost all my gear and HAD to start over, instead of flagship features I’d focus on fun.  The A7Cii or the Nikon Zf, last year I couldn’t decide so I bought both.  Hundred of thousands of shots later, I only kept one, but it wasn’t autofocus, color science, or the photo vs video workflow that made the difference. Making the switch feels like deja vu. Sooner or later, it’ll be time to start over.
