Yes, the D850 is a prosumer camera....a prosumer body is not referring to the quality of the camera: it refers to the BUYER the camera is aimed at. I figured everybody knew that. The prosumer is the BUYER. PRO-fessional con-SUMER, ergo "prosumer".
According to Forbes magazine, prosumers are also, today, in 2018, considered to be __product and brand advocates__.
The original meaning of the word prosumer is the buyer who constantly buys the latest,greatest thing on the market. The prosumer wants the highest-rated specifications...the most megapixels, the latest technical advances, the most-sophisticated features and the widest feature set.

A lot of people get butt-hurt when their favorite camera is described as a prosumer model, but there's the flagship level cameras from Canon and Nikon, priced in the $8,000 to $5,000 range historically, and there are the high-end consumer AKA prosumer cameras, at around $3499 to $2900 or so at introduction.
The term prosumer means something. It's not a bad thing. The prosumer wants ALL of the latest bells and whistles,and he or she wants to buy whatever is new, exciting, and which exemplifies the latest technology and latest efforts of the brand. The professional consumer, the prosumer, will buy a new item as soon as it is available, and will often advocate and talk about their purchase on-line and to others, and will try to influence other people to see the value of their latest equipment purchase.
Working professionals, now a very small minority in the photo world, often have MUCH less-fancy, more-outdated, and often beat-up and worn equipment that they know how to use, and which the typical prosumer would describe as obsolescent, outdated, or old-style. Note that Nikon flagship cameras now LAG behind the prosumer, high-end enthusiast, and entry-level models in megapixel counts. One group values bragging rights much more so than the other group.
The Nikon D3s is still a fairly popular camera with working photojournalists, as is the now-outdated D4 and D4s pair, and the D5 is the current flagship. The D800,D810 series, and the D850 are all cameras aimed at "prosumers": both the professional consumer/constant upgraders, and the people who advocate for the company, and the brand, and the model, on-line.
This definiton of prosumer, the band-advocate type of prosumer, has been around for almost a decade.The Shift from CONsumers to PROsumers
See this Forbes article from 2010, describing what a prosumer does:
"The term “prosumer” has transformed from meaning “professional consumer” to meaning “product and brand advocate.” Rather than simply “consuming” products, people are becoming the voices of those products and significantly impacting the success or failure of companies, products, and brands, particularly through their involvement on the social web."
Again..."prosumer" is not a put-down...it's a very specific thing. The prosumer market segment is like free advertising, and free on-line promotion. Now that YouTube has become a huge marketing field world-wide, the camera makers recognize the need to get prosumers to make advocacy videos, as well as to blog about their prosumer-oriented equipment. The camera makers design and sell cameras for prosumers, and professionals, and serious amateurs,as well as for everybody in-between.
