The Z6 seems a clear win in terms of EVF, getting the better EVF that the A7III lacks. The Z7 does not net this advantage,



Dpreview says the Z7 EVF displays the LV image at the full resolution whereas the A7R III EVF displays a reduced resolution image for LV and full resolution only in playback.


Until the Z7 is in the wild, the impact of that is unknown. So I won't call the Z7 EVF superior to the A7RIII right now.


I personal don't think there is any doubt that Z7 EVF is superior now. DPREVIEW stuff mentioned it and Multiple initial feedbacks from first hand review also confirmed it. Even there are many current MILC used this 3.69M EVF, they were not implemented the same way either in optics or electronics.

I believe the A7RIII low resolution during shooting is true based on all discuss linked in this thread from DPREVIEW discuss.
People also complained that x5 is blurred (based on low resolution version I guess) and only x10 give full resolution review during magnified shooting. (I even believe this is related to Nikon Z7 low battery rating for CIPA because of high resolution live feed EVF ).

Again, I don't know exactly how Sony implement this. However, 42M sensor only take raw data, LV implementation is like video feed that require either downsample the raw data and do the JPEG(or other picture format) feed at 60/120fps, or they just sample low resolution raw data from sensor directly and convert to JPEG feed,(most likely this way IMO) Either way, this low resolution mode will reduced process load and battery power.

3.69M EVF at full resolution is about 1280X960 and at full 120FPS(for A7RIII spec) will give about 150M/s. It is not a light load by any means especially during shooting.

I really want to see how Canon R implement this. I also wonder about how FUJI and Leica Q&SL did this.
