Absolutely right - you cannot form a definitive conclusion with just one sample - not even a series of samples for that matter, as my test methodology may be very flawed to begin with.
Would I be confident in doing paid landscape work with my E-M1.2 vs the A7R2. That depends on the demands of the client and/or the end use. If you are having to show fine detail in the image and/or make a very large print i.e. upwards of 60" or shoot in low light ... No, I am not confident. But for less demanding work in good light ... Yes.
The High-Res mode is a definite plus to have in situations that work i.e. with no movement. So it has its uses e.g. architectural photography, product photography, some landscape work, etc.
I understand that one example isn't enough to make definitive statements, but I'd like to ask if would you say you could confidently do your landscape and paid work with your E-M1.2 instead of your a7rii? I see what people like Diego can produce with an m43 camera, and it makes me think, "why would I need more than that if someone else can regularly turn out such great images with it?"
