Nikon D850 vs Nikon Z9

It does have an issue that I want to make everyone aware of. First, this camera has a steep learning curve. I bought a book to help me climb the curve a little faster. There are many controls within the camera settings as defined by the software. Second, I've had an issue with the mirror getting stuck in the up position twice. The first time I took it to the dealer and it was repaired in about 15 minutes. The second time I looked through several blogs and found a fix that took about a minute. From what I can tell this is a known issue for newer Nikon DSLR's. If you find yourself in this situation try this fix (worked for me, hope it works for you); -Remove the lens -Look on the left front side of the shutter box and see a small black flat lever sticking out about an eighth of an inch (its spring loaded) -Using your finger gently push this lever down until it stays depressed in the down position -Check for crud on the mirror -Reinstall the lens -Turn the camera on -Depress the shutter button one time Sensor. The D850 functions far beyond expectations in many shooting environments. The combination of available high ISO settings and high resolution sensor allow you to take great pictures in low light that many cameras cannot even contemplate. The high resolution sensor permits extreme cropping and or large prints without pixilation. Weight. It's weight does not lend itself to convenient use while traveling, however, for me, the picture quality makes it worth lugging around. The camera body itself weighs about 2.2 pounds. Adding the battery grip runs it up to about 3 1/2 pounds. With my Sigma 24 to 70 zoom the wait goes up to 5 1/2 pounds. That's a lot to be lugging around your neck but it depends on how bad you want good pictures. The D850 to the Z9; the Z9 weighs .8 lb more. Battery life. The D850 will take approximately 1800 shots on one internal battery. Mirrorless cameras run about 1/3 of that at best. I would really like to go mirrorless but the tech hasn't developed enough to compete with the D850 battery life. Plus I just don't like carrying around a pocket full of batteries to feed my camera. While on this subject I wanna comment on batteries as they relate to the mirror hanging issue. Some owners believe the mirror hang issue is related to battery type, condition, temperature or aftermarket status. I did not find this true in my situation. Knowing what I do would I buy it again, yes.

Just the feeling, holding it my hands, the size and ergonomy is perfect.

Best experience and best quality
