I will start with mine:
I started off with my parents Canon 400D + 18-55 kit lens in September 2022.
Then a few months later I bough an A6000 kit with the 16-50mm, camera bag and a sd card (It all as a kit).
I got a Tamron 35mm f/2.8 for my Sony at my birthday back in August.
Let me hear your upgrade/gear path!
Nikon D50
Nikon D300 x 2
Nikon D800 x 2
Nikon D750 x 2
Sony a7III
Fujifilm X-T30
Fujifilm X-T3
Fujifilm X-T5
Sony a7IV x 2
These are all instances of trading one body/pair of bodies for the next. I did also get a Ricoh GR IIIx in 2021 that I’ve kept since. I also don’t know how many film cameras I’ve had along the way, but it was a bunch (Nikkormat, Nikon F4, Nikon F5, Olympus XA, Leica M2, Nikon 28Ti, Olympus PEN EE half-frame, a bunch of lesser-known 35mm SLRs, Rolleiflex 3.5 and Yashica 120/medium-format, etc.) I’ve since sold them all.
