One thing I love about my A7S is the ability to tilt the screen and take candid photos of people while we're having a conversation. Also that thing pretty much shoots in the dark so I find that magic.
I regret not buying a Sony when I got my Canon 6D. Almost all of the lenses I use now are old/vintage and it sucks not having image stabilization for the extra 2 stops and a digital viewfinder to properly focus the lens. I almost resold my 6D many times in the past but I got too attached to it to ever pull the trigger.
