My first venture into a interchangeable lens mirrorless was with a Canon M 18-70mm and the 22mm f2 and eos adapter I loved the images you got from the 18mp sensor the downside was in bright light it was difficult to compose and view images.
I then went to Fuji with a X-pro 1 with 18mm f2.0 & a 27mm f2.0 on a crazy priced offer new shortly after I added a Fuji X-T10 and further lenses.
I then picked up a Lumix with short kit zoom lens but that was sold on fairly quickly to a friend who was after a small pocketable camera.
I then dropped on a OMD-EM5mkII and added a 17mm f2.8 prime
loved the pocket size you got with that combination.
In the meantime I added numerous lenses and bodies and flash to my Fujifilm X system.
Still enjoying both systems 12+ Fuji bodies most the line up of fuji lenses.
Oh and 5x OMD-EM bodies 1 pen body 5 zooms & primes.
Truth is nobody makes bad cameras its just a case of which system meets your needs and pocket.
I also own Canon Nikon and Pentax systems which rarely ever see the light of day these days.
My advise is go to a dealer and handle the different models your interested in and handle them all and delve into all the different MENU systems !
I still find the Olympus menu the most difficult to navigate around but that's just me.
