OK, but from $1000 up to $15,000 there is a road 15X longer. I think what everyone says is: why twice the price (DSLR-wise) ?
It depends who you are and what you shoot. Can you put a price tag on 1-2 stops of DR? Or ASP-H sized 4K (not available anywhere else)?
Like most technology.... The gap between low range to mid range is usually much bigger, for much less, than the gap between mid range and high range.
