Let's see: Introduction to the market of the M3 was April 2015. At that time I had the DP1 Merrill for almost a year and you got yours second hand. Sorry, you lost. May 2014: Arrival of DP3 M, May 2015 DP2 M completed the trio.
First Fuji was around NewYear 2016, with the firmware 4.00. BC, You lost again, because it's only a tiny Canon. And btw. the EVF was onboard of the Fuji. I didn't have to buy an additional EVF-DC1 That's so sweet.... and the electronic shutter is very silent, maybe someone told you? No? Pity.
You confuse me with Klaus, it is Klaus who bought an M3 for lens review purposes.
I bought my mirrorless camera in 2013. And it was not 2nd hand.
Rest of your post, talk about moving goals....
