The first camera I bought myself was a Nikon D60, and I have stuck with Nikon ever since:
Nikon Z6: recently I updated my body to a Nikon Z6 from a D800. I had wanted to go mirrorless for a while to give me a more compact and lighter weight option...and I love it.
Sigma 150-600mm f5-6.3 (C): for most of my wildlife images I use my big Sigma. It might not be the best telephoto on the market but it has served me excellently.
Sigma 150mm f2.8 Macro: It might be a bit heavy for a macro lens, but it's probably my favourite lens. Shooting insects is difficult enough, so this excellent lens is perfect for keeping enough distance between me and my subject.
Sigma 1.4 Teleconverter: A more recent purchase to complement my macro lens, this little converter gives me just enough additional reach to avoid disturbing my more sensitive subjects like butterflies.
