Originally posted by Kiwi645hauler ...using the new EOS R3 by Canon as an example, the less than 1" LCD EVF has 5.76 million dots and a 120fps refresh rate, while providing 100% frame coverage at .76x magnification and a 23mm eye relief.
An EVF screen around 23mm diagonal (at 3:2) or smaller does mean the pixels are not discernible according to my calculations (well, someone else's in inches and my conversions). As for the 120 fps refresh — is that just a display characteristic or is it true of the entire EVF system? In other words, will the camera get the info from the sensor, process it, calculate shooting attributes, process for display, and overlay data at 120 fps also? Cameras aren't known for high end compute power but I don't know how much it would take to achieve this.

Owww!! I just looked up the price of the EOS R3!!
Fair to say, I think, that while this EVF is potentially in the zone for "as good as OVF" it's gonna be a few years yet before it's in the consumer or even prosumer zone on price. If EVFs survive.
