The Nikon D850 is now over three years old, but it remains something of a high watermark for DSLRs.
To say the specification is comprehensive is an understatement; the D850 is packed with desirable photographic features, while it backs these up with impressive performance and stunning image quality.
Live View focusing speeds could still be better, while the rather rudimentary SnapBridge connectivity offered is disappointing; but those issues aside, whether you're shooting weddings, landscapes, portraits, action or wildlife, the D850 won't leave you wanting.
A much more versatile proposition than the D810 (and its closest rivals), the D850 is a brilliant DSLR, and perhaps the most well-rounded DSLR we've ever tested.
Sony Alpha A7R III
Perhaps the closest rival to the D850, Sony's 42.2MP full-frame mirrorless camera is a brilliant piece of kit. Autofocus performance is impressive, while it's capable of shooting at 10fps at full resolution. Not only the most well-rounded mirrorless camera you can buy today, but one of the best cameras out there right now.

Canon EOS 5D Mark IV
Until now the 5D Mark IV was our pick of the full-frame DSLRs available, but the D850 eclipses it in pretty much every way. It's still a great DSLR, but the D850 is the one to go for if you don't have a huge investment in Canon lenses.

It may be Nikon's flagship DSLR, but unless you need the even faster 12fps shooting speed and bullet-proof build quality the D5 offers, you're better off saving your cash and getting the D850; it's the much more versatile option.
