In 2010 I jumped into Micro 4/3, buying both the Olympus EP1 and Panasonic G1. The Olympus got me interested in the older E-system and I ended up switching. The Olympus standard 4/3 gear was cheap at the time and the lenses were outstanding. The best thing was the gear was smaller and lighter than the Canon stuff I had been using since 1998. But in early 2016, I bought two Fuji XPro1s and had a sea change in equipment and working procedures. I've used nothing but Fuji gear ever since.
As for the next 12 months...nothing really planned at all. I've been considering the possibility to a full frame camera but it will be an older model. Possibly a Canon 5Dsomething so I can make use of the lenses I still have. Possibly a Sony A7something to be able to use the Zeiss 35/2.8 and 55/1.8 lenses. But probably nothing.
On second thought, what I might buy is a film scanner. I despised scanning when I was doing it in the past but I have tons of B&W negatives and slides from which I really would like to have prints made. So there's that.
