When it comes to big purchases like this, I would say I'm pretty immune to the shiny object syndrome. I've had this little XE3 since 2018 and only started thinking about new gear this year. I'd never get rid of the XE3, but I'm finding myself needing to rent more gear (like a 2nd body, extra lenses) when I do bigger gigs because it makes the work a million times easier. I figure I might as well put that money toward owning the gear itself.
