Originally posted by rawr Even high quality EVF's like the external Sony FDAEV1S on my NEX produce dizziness and eye fatigue after moderate use. Perhaps because my Sony EVF doesn't seem to like people who wear prescription glasses.
EVF's keep on getting better, certainly, but I would personally be happy if Pentax didn't rush to make a serious camera that had an EVF as the only viewfinder option.
I wasn't a fan of EVFs, having tried a few in the local camera shop (Fuji and Sony), but despite that, I bought into the micro four thirds system with a Panasonic GX7 (don't worry, my Pentax system isn't going anywhere). I don't find the EVF of the GX7 too bad, even as a spectacle wearer, but I think the point of it really is to use when the rear LCD can't be seen clearly, e.g., when in bright sunlight. So, I see it as a supplement to the rear screen, not a replacement. The fact that the screen tilts is a help, too. Also, I don't find it gives me headaches, like with some people. This is far from saying that I've become a convert - I still much prefer the OVF of my K-3, but it wasn't as bad an experience as I feared. I'd love the option of an EVF on my Q series cameras, of which I'm very fond.
