Despite how embarrassing it may sound, I actually do care a bit
Because so far my favorite image rendering stems exactly from the combination of a Sony sensor and a Nikon processor, and I happen to think that image renderings from different camera brands and models actually differ somewhat.
So knowing that the D850 model uses that good, old and well proven combination only makes me want the D850 even more.
It makes me feel very confident, and I would buy the D850 in a heartbeat, if only I could afford it

Unfortunately at the moment too many other expenses are threatening.
But perhaps a used D850 will be within my reach if mirrorless Nikon FX models with electronic viewfinders take over a big chunk of the attention in a not too distant future.
*) in my country D850 is 30195 DKK, which equals 4052 EUR, or 4700 USD
