I have a Olympus OM-D E-M10 Mark III. It was recommended to me by @Monkey when I was moving on from a point and shoot to a camera with interchangeable lenses. I love it. When I got my Canon M5, I thought of selling the Olympus because I didn’t think I needed two cameras but they are so different and the Mark 3 is so easy to use I decided to keep both. They are both really good cameras and I use them for different purposes, different moods.
The Olympus macro lens (the less expensive version) is really sharp and the x2 on the camera comes in really handy. And the IS on my Olympus is fantastic! All my macro shots are hand held but they are really sharp, thanks to the in-camera IS, auto-focus is really fast, too.
And I love the EVF. I find it much easier to use than the one on the M5.
What Olympus lenses do you have? I do a lot of flower macros so I use the 30mm macro lens the most but the 25mm and 45mm are both really sharp (even when shooting wide open). The bokeh on both lenses are really nice, too. Not as creamy and smooth as the Canon, I don’t think, but it’s still very nice.
