I mean, that tracks for 9 years of updates to three lines of camera
most of these are still actively for sale on sony's website, simultaneously
Wait a second I could get a new a7R ? Like ten years later I can pick one up brand new?
that one is out of production but sony's website still has a price for an A7R II
How about that, and it's not even that bad.. shoot, I have some minolta AF lenses that are compatible. Maybe I should save up.
