Great review as usual, did not expect anything less from Jono.
But I must say that his and my photography world have evolved in pretty much diverging directions. While he loves the S1 (and I guess the S1R as well) these cameras are for me while still being some of the best FF mirrorless cameras, simply far too big, bulky and heavy. I also cannot base anything I buy on Leica SL lenses which can be easily used with high success on these Panasonic FF cameras as I only have M lenses which I would use on these cameras. And for M lenses simply the Leica M10 is the current state of the art camera to use.
So here we go for whom this might be interesting ....
1) I am happily staying with m43 (Olympus PRO) especially after finishing my last vacation in the Gulf of Mexico - EM1.2 with mostly 2.8/12-40 - which is a stellar and very robust configuration, especially in the very humid climate of Florida's coast on Gulf of Mexico

2) I am of course considering to go into FF territory (mirrorless) again and the most likely contender will be Nikon with the Z7 - delivers excellent results with Z lenses where we have already a few excellent examples today - and all is perfectly suited for the use of M lenses - AND is MUCH lighter than the S1 / S1R.
Here some samples with the native Z 2.8/24-70 - an excellent lens for all round shooting ...

3) I might even still go with Fuji X APSC instead as soon as the prices of X-T3 come significantly down or the X-H2 becomes available - no samples here but one can find plenty around on the Internet for the X-T3
4) no hurry at all as I can wait and see where Nikon Z and Fuji X will further evolve to supplement my Olympus m43 kit as I am more than happy with the results from this system today!
