I’m a Sony user now, but I started with Nikon, which I loved. I almost purchased the original Nikon Z6 by placing a preorder, but after doing some further research, I realized that Sony was leading the way in mirrorless cameras, especially in terms of autofocus and other features at that time. The main reason I’ve stayed with Sony is that I have a lot of lenses for my current cameras, the Sony A1 and the Sony A9 (which I still love). Switching to another brand would mean losing money, and I'm not wealthy. In my opinion, the major camera manufacturers—Canon, Nikon, and Sony—are all excellent choices, and you can't go wrong with any of those systems. Before anyone criticizes me, I acknowledge that other camera brands may be just as good; I just haven't had much experience with them outside of the big three.
