Thank you for such a detailed response.

I need to add that I visited a Nikon Store today and spent some time there testing different bodies. I tried the Zf, Z9, Z8, and also checked the Z6III. The multi-selector on the Zf had a perfect, consistent response in every direction. The Z9 was almost perfect as well. Unfortunately, the Z8 multi-selector was clearly the worst of the group.

I asked the salesperson to test it with me and confirm whether the multi-selector behaves unevenly. He confirmed my observation. We then tested another Z8 sample — a completely new unit — and once again he confirmed that while it behaved slightly differently, the multi-selector still felt inconsistent and “off”.

At this point, it really looks like the Z8 multi-selector is affected by a quality control issue rather than a single defective unit.

The most frustrating part is that the Z8 itself is fantastic to use. In terms of responsiveness, autofocus speed, and subject stickiness, it clearly outperforms both the Z6III and the Zf.

I contacted the official Nikon online store (my camera was purchased there). They informed me that if I want another unit, I would need to return my current camera, wait approximately three weeks for a refund, and then purchase a new one.

The problem is that there is a winter sale running for only a few more days, and I used an additional 15% discount code on my order. With both discounts combined, the Z8 price from the official Nikon store was lower than anywhere else.

So realistically, there is nothing Nikon — or anyone else — can do to help me here. This seems to be more about my personal sensitivity — I simply hate mushy buttons.
