So, I've had a few days to think about this, I'm a hair's breadth away from selling my EM1.1, EM1.2 and PRO lenses. I think the hockey shooting was the wake up call. When I looked at what came from both systems, the Nikon was the clear winner. I've about 80 "keepers" from both cameras combined and 80% were from the Nikon. I was hoping and praying that the Olympus system would at least match Nikon, but that is sadly not the case. The gap has lessened, but that is about it. I'm sure it is a bit unfair on done levels to compare the Nikon D500 to the Oly EM1.2, But we are talking the very best of one system to the #2 of another. I'm trying to find a good reason to justify keeping the m43, and I will keep the PENF and some smaller kit lenses for.my personal use. Really the only thing that I'd miss is something on the long end, and I've got a good line on a used Nikon 200-500/5.6 that could fill that void. Other than that, I might be missing the video end, but the D500 can do 4k. I know this is my decision, but I just wanted to throw this out there and see if anyone could think of any other reasons that I have not considered and should before making the sale. Thanks in advance.
