One key task when reviewing a new camera is to answer the important question "Who's it for?" This challenge is a bit more difficult than usual with Nikon's new Nikon D850 DSLR, because this powerful camera is one that defies classification.

Pushing the limits of what a DSLR can do are cameras like the Nikon D850, a new top of the line full-frame camera. It offers a lot of features which are innovative and really cutting edge.

Nikon wetted the appetite of many photographers earlier this year with news that it was working on a follow-up to its high-resolution full-frame D810 in the form of the Nikon D850.

Either way, my personal feelings don’t at all negate the fact that the Nikon D850 is a fantastic camera.

With expansive resolution, a capable autofocus system, fast burst shooting and great image quality under almost any situation, the D850 is the best DSLR on the market today, and among the best all-around stills cameras we've ever tested. Live view autofocus and video modes could still use some work, but the camera's capabilities handily outshine those deficiencies.

Photographers who photograph anything from landscapes to sports and want the best possible image quality in a DSLR.;

Those shooting incredibly fast action that requires higher burst speeds and those who require a more refined video feature set;

The best DSLR money can buy at the moment......saying this also keeping in mind the likes of Nikon D5 & Canon 1Dx

The Nikon D850 is one of the best DSLRs ever made. Period. Full stop. Yes, we had a few notes -- the Live View AutoFocus is slow, you'll see some rolling shutter in video, it's a little hard to find settings in the endless menus, and Snapbridge has a few bugs (and will eat your battery!

Gorgeous imagery; Amazing dynamic range; #AllThePixels; Incredible Auto Focus (via optical viewfinder; Accurate metering; Very good 4K video recording; Up to 9fps full resolution continuous shooting (with the optional grip; Ergonomic button controls; One of the best DSLRs ever made

Dense menus; Slow Live View AF (for stills & video; Missing pro video features (S-Log; 10-bit HDR; etc; Choppy in-camera slow motion HD video; Snapbridge App still needs some work

If you're need pro-friendly features and can stomach the price tag, the Nikon D850 is the best DSLR you can buy today.
