Back to the research board I went. However, in this case I wasn’t going in totally blind. My cousin, a solid photographer in his own right, owned an Olympus E-M5 Mark II camera and swore by it. More importantly, I had seen large scale prints from that camera. So I knew image quality would be quite acceptable.
As size was a concern, I had two choices in Olympus. They older (and now cheaper) E-M5 Mark II or the very recent (and noticeably more expensive) Mark III. So, as before, off to the web I went, searching technical and user reviews of both cameras, along with comparisons between the two. After a lot of reading, I opted for the MarkIII, primarily because it was current technology and it had better video capability. As a long time stills photographer, I’m constantly trying to incorporate more video into my workflow. The best way for me to do that is make videography as easy/simple as possible. The Mark III seemed to fit the bill in that department, too, but honestly, only time will tell in that regard.
Other than video, two features of the camera were of great interest: the purported 5.5 stops of in-body image stabilization (IBIS) and the Live Composite bulb mode.
Below, I've included some size comparison shots of the three cameras. The Lumix is now proudly owned by my wife. The Nikon D750 and my new Olympus camera are now my primary and secondary cameras. While not as small as my Lumix, the Olympus is still noticeably more compact than my D750. Granted, we are also comparing full-frame to Micro 4/3. But as I mentioned early, the Lumix G9 (also M43) was nearly the same size as the my D750...
