Excellent performance, the best Hybrid
The best hybrid.The body of the D850, the AF system of the D5, the Live View of the Z6II, and the soul of the D750; an impressive camera, with an incredible ISO range and an excellent signal-to-noise ratio, Incredible performance in low-light conditions (for live-view). A robust magnesium-alloy chassis, a true masterpiece in the display of settings on both the LCD screen and the viewfinder. Probably the best battery life for a DSLR camera (without a vertical grip), compatible with almost all types of Nikkor lenses (you can save configuration profiles for up to 9 non-CPU lenses! This saved my life). The best menu system: settings are easy to locate, and the customization options are incredible. A genuine 9/10.However, it is a shame that it truly lacks accessories: it does not include the 10-pin remote terminal for compact wireless transmitters (it only supports the WT-7A, which considerably increases the camera's size), it does not offer the option to use a vertical grip, it lacks a studio flash sync port (PC Sync), an interchangeable eyepiece, and a viewfinder shutter, nor does it feature GPS, a joystick/sub-selector, or backlit buttons. Consequently, it is not an ideal choice for professionals looking to make a living in photography, the D850 would be the perfect option for event photography, even in low-light conditions. Because the D780's Viewfinder AF sensors will not perform reliably in low-light unless paired with a fast f/1.4 prime lens, which comes at a considerable cost. So low-light photography must be done with live-view 75% of the time. Nevertheless, this camera is a true hybrid, not just a blend of the D750 and the Z6, but a device that incorporates the very best aspects of numerous other Nikon flagship cameras into a single body.My experience with this camera has been fascinating. Its size is ideal for someone with big hands like me, the buttons are positioned perfectly, and the camera's ergonomics are among the very best. The durability of the body is astonishing, I have taken it to scorching deserts, snowy taigas, arid mountains at altitudes of 3,000 meters, salty beaches, and tropical jungle environments, and this camera has never failed me (at least not mechanically). It is worth noting, however, that both I and many other users have encountered issues with the side rubber grip, which tends to come loose within just a few weeks of acquiring the camera. This isn't necessarily linked to demanding use, it can simply happen if you get unlucky. Nevertheless, it is an easy fix, and it only affects the aesthetics, along with the weather sealing to a minor extent, since that section covers some of the screws on the camera body.
