Bob:
Your list is a great start for sure.
I have been tempted to look at the Olympus, mainly for the screen/video work. But have the X-T1 and still use it often.
Your point on the lenses for the Fuji is good one, as all their glass just works and works well. With the latest Firmware, 4.0, my AF is excellent now with all my glass and I really give Fuji Credit for this. Low AF is excellent now, I just don't get many misses anymore.
After looking at the A7rII, I realized I wasn't giving Fuji enough credit on their EVF, which is also very well designed.
My only real issues with the Fuji:
LR can't get the finer details out of the files, at least to my eyes. Rocks, lichen, etc can take on a plastic look. The only software I have used that can get the details is Irident but it has really no tools and you can't output it as a dng, and re-import to LR, (would love that just for the raw conversion, then finish the work in LR. LR has definitely gotten things better as the haloing around finer details seems to have corrected (tree leaves blue sky). And Adobe seems to have made it a point to work closer with Fuji so I am still hoping for improvements.
The 16MP size of the sensor, I would prefer 20MP to 24MP just for my work and prints. I stitch a lot with the Fuji but there are times I can't and the file size is just a bit small for a 30 x 40 print at 300 dpi. I had hoped to see Fuji grow the MP on the sensor, but that seems not to be happening.
You can't get 100iso in raw, never have understood that, but since the days of the Fuji S2 200 iso has always been the raw limit.
