It has nothing to do with how you look. It is about getting the shot. I could not get most of the shots I do without an OVF or EVF. I doubt I am alone.
No, you are not.
Just checking -- I wasn't sure -- here are the digital full frame mirrorless rigs released to date (that I am aware of):
Sony RX1/RX1R: Nothing onboard, but modular OVF and EVF were offered (both optional, I believe)
Sony RX1R II: EVF built-in
Sony a7 (6x models to date): EVF built-in
Leica Q: EVF built-in
Leica SL: EVF built-in
Leica M (not sure of the hard figure, but it's a number of designs): those have been 100% OVF over the years, correct?
Unless I've forgotten one, I am not aware of a single FF mirrorless rig that didn't have a VF of some sort.
Medium format are deeper waters for me that I am not well-read on. But I believe the Fuji and HBlad MF mirrorless setups have EVFs. There's also the nutty Alpa 'body' (more of a properly spaced out frame and mount) + MF digital back 'mirrorless' frankenstein rig. That
one might be VF optional.
