80D vs 6D vs A7 ii
I have a 40D but don't use it often because of the size and mostly because it's quite old. I've been borrowing a 5D Mark IV from a friend and love it, but that's outside of my price range.
What's the best use of my money on the used market? I only have an 85mm 1.8 and 50mm 1.4, so moving to Sony wouldn't be a big deal. I pretty much only use the 85 anyway. Could either adapt it or just sell it and get the Sony prime.
