I have owned and used D300, D810 and D850 and got the Z as soon as it shipped. So far I have the 24-70 f4, 85 f1.8 and adapt all my other lenses. Upgrade fixed my initial focus issues- great now, but my experience is limited to less than 125mm. I love the lightweight and ease in transition from D850 menus. I have bifocals but viewfinder isn´t a problem (a bit of a surprise). Very low noise at iso 6400 - hard to tell the difference from my D850.I am very pleased, so far.

There´s a lot to love about this camera and its new lens family. It´s light. Its dynamic range and capture accuracy are wonderful. Its ergonomics are familiar and intuitive. Its physical and software versatility are terrific. Its on-board wireless capability is great. Its new lens family takes Nikon glass to another height. I´d only hope for a few options and changes: 1) Faster and more accurate focus, and 2) The more universal mini USB port on the camera side.

Nikon´s Z7 isn´t perfect, but it´s what I was hoping for and a good indicator of an excellent new mount and system. Previously I had a Nikon D750, shot fairly extensively on a D800 and used mirrorless Panasonic Micro 4/3rds cameras as my day-to-day cameras, documenting construction progress on our engineering projects. I was hoping to get a high resolution, full frame camera with a smaller, lighter body than the D800, and the WISIWYG views of my mirrorless cameras. Nikon´s first entry into full frame mirrorless is impressive and getting better with firmware upgrades (please keep them coming).

I use my camera for family events, wedding, baptisms and other occasions when the shutter noise can be disturbing with an SLR. I can now shoot as many frames as I want and not disturb. Fantastic!
Image quality is great. The electronic view finder makes it difficult to take a bad photo. You know immediately if your photo is going to be good, and if not you can make immediate corrections in exposure.
Very compatible with all my old Nikon lenses. The adapter makes a solid connection. Autofocus speed does not seem affected by the adapter. Great camera!
Have also used it for filming indoor video with excellent results!

The Nikon Z7 is more camera than I am photographer. As a new DSLR user, the learning curve was steep, but worth the effort. The Z7 allows me to experiment with my photos in ways I would not have imagined before I bought it.
Complaints: Tutorials need to explain when, why and how to use the different functions. The same goes for buying lenses.

Is light and easy to work in all conditions, with easy access to the menu.
High precision and fast focus in all conditions. The ayes detection is amazing.

I have a Z7 and D850. I decided to use the Z7 with the new 24-70Z 2.8 and 14-24Z 4.0 and the 850 with my long lenses 100MM and up.

I love the weight of the Z7, the interface is easy to use and the resulting photos for the most part are what I expect. I use the Z mostly when I hike or travel. I have run into situations that concern me with the Z that won´t allow me to give it 5 stars.
First - If I shoot 5 frames in a row using Snapbridge. the Photos exposures will be inconsistent. No changes to the settings, Just Shoot 5 in a row in a 30 second period and the lighting in the photo comes out different., cant explain it.
Second - Depth of field Preview - Nothing like I am used to on the 850. On the Z it is inconsistent and not reliable.
Yes I have all the latest updates. I had hoped this was something to fixed and that the updates would do that. So far... No go

I still would not give up the camera. Light weight, feels good. Aftermarket brackets for my tripod are great and cheap. Sensor delivers even IF I can´t tell when I take the shot.

I use this camera and the 14-30 Z lens for real estate photography. It´s a great combo, small , light and with Great results. It produces a sharp image.

I love this camera. I originally purchased the Z 7 as a back-up for my D850 but now I am keeping the D850 as a back-up for the Z 7. I not only can use my prime lenses with the FTZ adapter but purchased 3 of the S lenses. As photography is ´´My´´ passion the Z 7 has not disappointed me in any area.
