An A7ii with a Sigma EF 85mm f/1.4 (incidentally the whole set up used is about half the price of an iPhone 14 Pro).
The X100T is a great camera for the experience, but it kinda sucks for low-light. If you want good low-light performance, then image stabilization is a must and full-frame with a lens faster than F2 makes a huge difference too. In the end I can hand-hold comfortably at 1/4th of a second, and the camera itself takes in 4x more light, so low light performance is much better than on an X100T.
I can upload the pictures I'm talking about later today, if you want.
