Excellent lens, with fast autofocus still, sharp, silent, very good in low light conditions, I haven't tried it with flash, the only downside I would say is its weight!

The 24-70 F mount orthodox non-vr broke so the logical choice for the Z6ii was this one. I was impressed since the D750 that it was a prime-lens killer with so much sharpness that I had never seen in a zoom. The current 24-70 on the Z6ii has managed to become an even bigger prime-lens killer to a point where you can't believe it. The way it depicts the edges, the hair, the textures is sick... Everyone talks about the 4th at half the price and that they don't see a difference in the image. I saw it and this lens is the king.
In terms of handling, the lens sticks to you like a magnet. Even when it's open, it doesn't change significantly.

Build quality: The Zoom ring gives me the feeling that in a few years I will want another one like the 24-70 I had before. Otherwise, the focus ring and the wanna-be aperture ring are hard and precise. However, I really completely disabled the latter because my hand accidentally touches it and bothers me. If ALL Nikon lenses had the same function, maybe I would use it, but for example in the 14-30 f/4 Z mount, which has the same size ring, it is the manual focus override. Also, the lens hood has a fabric lining inside that is very susceptible to scratches and dirt and I don't like it, but it locks when it is open in a position and does its job well. The Oled screen I feel should not exist. Susceptible to fingerprints and not particularly helpful but ok it's a nice marketing gimmick.

Now this lens has an L-fn button which I personally set to change to subject tracking. Very useful and convenient for a 24-70 where your frames are generally and you have 15 people you want to focus on a specific one.

If you really have the money for quality glass, it's worth it. If you don't, the 4th kit is fine. If you didn't get it with the body, used it is at a good price since new it is not worth the 1000 euros you can spend on the 24-120 or the 28-75 f/2.8.

2 MONTHS USAGE UPDATE: I went to a specific store in low light conditions with the same camera z6 ii, the same flash but the old 24-70 F mount Non VR, with the same Nikon SB900 flash, the lens struggled to focus as easily as the previous one. My most important image came out 20% blurry and I had to use AI to fix it. And unfortunately I have noticed it again and again. Unbelievable for a 2500€ lens

And at 2.8 on the edges, you can see that it holds up very well. I have a Tamron 24-70 2.8 and at 24mm it distorts a bit and has chromatic aberration. This Nikkor is the best that has come out. It didn't become the best 24-70 ever released by chance. Also, silent focus, very silent though. And very fast. You don't need to think about anything else if you have a Z-mount body. Don't go for used or another brand or even an F-mount. Sooner or later you will regret it. This comment is a personal opinion and is mainly addressed to professionals

Premium lens from the moment you hold it in your hands, this is the first impression!!! It's worth every last euro.

The sharpest lens at all focal lengths with beautiful bokeh!
Also completely silent focusing that will not create any problems in recording clean sound in videos.
However, it is worth noting that compared to the equivalent Nikon Z lens with an aperture of f4, I did not observe a significant difference in sharpness (I'm not saying that it doesn't exist, but that it is not visible, for example, in an A4-sized print). So, if someone is willing to compromise with this, it depends on how much of a difference the 1-stop from f4 to f2.8 will make in their work when purchasing the lens.

The best I have ever held in my hands. Sharp, the quality of construction is incredible, nothing creaks, nothing rattles. I wish the spiral for the filters was metal like in Fujifilm for longer lifespan. The front screen is completely useless, the eye never goes to it. Also, very convenient the additional ring that you can adjust to whatever you want and the extra button.

Incredible sharpness, silent and fast auto focus, very convenient and customizable functions (extra button and ring), overall it is an exceptional lens.

Disadvantages are the weight and size (which cancel out the advantage of smaller and lighter mirrorless) and, of course, the price.
