I've been through the exact same journey as you: so I'll tell you about my experiences
All I'm looking for is a compact 35mm lens and camera combo
So far I've tried
Sony 28mm, which I loved size wise but it was a bit plasticky and I really notice the difference between 28 and 35 (strong preference towards 35), and ultimately that also put the leica q out of my acquisition list (which sucks as I thought that was the answer...)
Haven't tried an rx1 but no viewfinder and ropy af, can see myself not getting on with it
Manual focus 35mm lenses- still not 100% sure about manual focus, even with peaking it's just not accurate enough IME
Sony 35 1.4, lovely lens, and I still use it for work, but it's heavy and big
So as I'm dead set on 35mm the options are:
6d with 35 f2 (the older one)
A7 with 35 2.8
A7rii with canon 35 f2 (the new one, as I don't think the old one will focus on the a7rii)
Want the leica q, but just couldn't get on with 28mm focal length
Hell maybe I could get on with it, that and the new macbook...
The thing about beautiful products is they inspire you to forget about compromised and reality ha
