Do you miss an OVF?

I am asking because I never had a full frame DSLR, mine only had a very small viewfinder, and so the A7 was an upgrade. I did have an old film camera though and did enjoy the larger optical viewfinder.

Finally, given that the A7Rii can use dslr lenses as well as native ones, it would be conceivable to build an FE system around Canon or potentially Nikon lenses and have the option of moving back and forth.
