Well if new features are brought to Fuji cameras with just firmware releases...why weren't those features in the camera from the beginning? Why does one have to wait a year or so to get the features? I can understand if hardware is the limiting factors...but adding some features or in fact quite often fixing existing features via firmware a year later and then bowing down to Fuji for this seems a bit much. Why weren't those features in the camera from the start?
Sometimes it takes a long time to make some of those features work properly while they still have a functional camera available. Some of those updates are after extensive use and user feedback, this happens with all cameras released but only some companies make the changes.
The focus improvements means they kept changing and finessing the algorithms. Take Nikon Z7, the focus is functional but far from top of the class. I’m sure it can be improved further, good luck getting Nikon to do it particularly if they plan to release a higher level body with better focus.
Will I want to have all those features from the beginning? Sure. I’ll take the subsequent improvements any day over “the camera that you bought is the camera that you will have, period” of Nikon and others.
PS. All the Fujis that I’ve bought have been good enough for me from day one, the improvements were bonus
