John, I had to look twice at your original post to make sure it wasn't something I posted in my sleep. My sentiments exactly. I went digital around 2009 with an aps-c Nikon. After they semi abandoned the DX mount in regards to serious lenses and the delay of the D400 that finally became a D500, I looked to other options. I liked the Olympus system primarily due to the IBIS and the reputation of the Zuiko lenses, but also the overall size and cost. Although the Pro lenses are a bit larger and still expensive, it's quite a bit less than full frame, and there was no real aps-c options at the time. I started with an EPL-5 with 14-42 and 40-150 f4-5.6. It was great for travel due to the size, and I was surprised by the quality of a few 24" prints made from this camera. A number of respected individuals at the time extolled the quality of the system for up to 17x22" prints. I recall an article on TOP by Ctein regarding the 16mp sensor as equal to or better than the best 6x7 medium format film options, which is where I was in the film days. So I added an EM1.1 with 12-40 f2.8, a year later the 40-150 f2.8, another year the EM1.2, then a couple primes. I would like to add the Panasonic 8-18, and a few more primes, but I do wonder about the future of the mount as it stands today. I've printed to 20x30" with the EM1.1 and have been happy with the result. Haven't yet printed anything larger with the EM1.2, but hope to try a 36" or 40" print. I've read a few well qualified sources that feels the best of the Olympus lenses, both prime and zoom, may be up to par for around 28-32mp, but diffraction has got to come into play somewhere. One of the benefits of a 4/3 sensor is increased depth of field, so being limited to 5.6 or larger negates that, unless you invoke focus stacking. I'm mostly happy with what the current system offers in regards to bodies and lenses. I am disappointed that Nikon never filled out the DX line, as that seems to be a good balance in regards to sensor size and performance, with what should be an appropriate reduction in size and cost of the bodies and lenses. I have occasion where a FF sensor would be of benefit, and may very well add something like a Z7 and a couple of specific use lenses in the future. Regarding sensor technology, I think we've about reached the limit of existing sensors, maybe something like a Foveon hybrid significantly advances what can be done with all sensors in the future. In terms of market share, Canon, Nikon, and Sony are already such established names, it is difficult for Olympus to gain any ground, though I'm not sure they really tried hard enough with marketing and pushing the system beyond people already at the enthusiast level. Most newcomers know the Canon and Nikon name, and end up with one of those to make an occasional 8x10, not realizing what could be done with m43. I get the occasional funny look when someone looks at one of my 15" or 22" prints then tries to figure out how it came from anything other than a Canon or Nikon.
