I agree. Yes high end professionals and agencies buy them but I think well healed enthusiasts make up a large chunk for the market.Where do people get these ideas? As someone recently pointed out, the average professional photographer earns about $41,000 annually. The top 1% are earning around $70,000.
And, seriously, do you really think more "big whites" are bought by professionals than enthusiasts?
Enthusiasts are only constrained by their disposable income. Professionals have to earn a return on their purchases.
The R1 for sure will be expensive. There will be plenty of buyers for it though.
