It began with the original OMD EM5 where I fell in love with Olympus and the form factor of Micro 4/3 sensors.
When the EM1 ii came out, I jumped on it like a bull dog on a pork chop and have loved it ever since. It's tough, well built, weather sealed, and doesn't eat up batteries. I've dropped it in snow, dust, and worn it in rain without worrying about it.
Recently I've been shooting all of my vide with it as well with great success.
A very capable camera for the backcountry!
