Like I said, the NX1 is the camera the 7D2 should have been.
If the 7D2 had an EVF only, I wouldn't be interested in it at all, because it would be essentially useless for my primary intended purpose.
Which is what?
Very high speed subjects.
If an EVF is essentially instant without lag, ...
Then it's in violation of the laws of causality. I have an EVF with a measured total combined lag of only 25ms (which is very fast as EVFs go) and it's just way, way too slow - a factor of at least 5.
it is superior to an optical viewfinder since it can correct for exposure (which is impossible in an optical viewfinder).
Which I absolutely don't want it to do.
If you work in low or high contrast light, you 100% need an EVF.
Interesting, then, how I've done it for all this time without one. Oh, an EVF is really totally useless to me especially in low light because it will destroy the dark adaptation of my eyes. I want the viewfinder to be dark when the subject is dark. And I've shot in extremely, extremely difficult conditions with an OVF. Try this - crop camera OVF, f/21 optics wide open, total darkness, 4,300mm equivalent focal length, hand-tracking and manually focusing on an object that's moving at orbital velocities and it only 9m long at 400km away. I did it successfully and was even able to identify the object. That would be totally and completely impossible with an EVF.
A lot of the resistance against EVFs is resistance against EVFs from 10 years ago. I have cameras with optical view finders and EVFs, and other than the exposure issue, EVFs blow optical out of the water with features such as peaking, view zooming and zebra functions that allow you to get proper focus and overall exposure. Optical viewfinders are a technology of the past, and cannot compete with modern EVFs designed for the future in terms of overall functionality. They simply cannot, they are obsolete.
EVFs are only really good for video for me. For stills, the only good thing about them is that they are better than using the LCD. I turn off all that nonsense information on my EVF cameras so I can focus on the subject anyway.
