I've asked this a few times and never get a good response. What is the difference in the A7 or A7R vs. NEX-7, 6 or even 5N EVF? The resolution and size specs appear to be the same. Is it brighter or what?

...lies in their sensors - affecting the quality of the input signal and S/R ratios, which influence esp. greatly reduced DR in shadows and highlights as rendered by EVFs in general - these are the two most affected areas of poor EVFs performance, as they most easily gave up in both rather dark and very bright scenes with lots of contrast. It suffices to close one's legacy MF lens from, say, f/2.8 to f/8, thus cutting the available light eightfold to witness the adverse effects on N7,

The better eye relief due to somewhat larger optics in newer implementation of the same OLED VF is helping a bit too, but it isn't decisive factor,

Hmm.. so, you're saying that the A7 EVF looks better because the A7 sensor (24MP FF) is better than the N7 sensor (24MP APS-C)?

So, you're thinking that Sony didn't really need to bother putting better glass in front of the EVF in A7 and just the better sensor would already have made a big difference? I'm not convinced. The lack of the rainbow effect is, for me, a big improvement in the A7, and I can't see how the difference in sensors would have anything to do with that.

Also, what is S/R ratio?

...I-st it was the same EVF as in A7, but now SAR says:

  • "finally got the A6000 EVF and AF info:
    • 1,400K dot EVF;
    • 179 phase detection points (on sensor);
  • and tomorrow morning it might be that all this was just a big load of FUD

but yes, in essence - concerning the previous exchange - it was what I was saying; Just consider that FF 24 Mpx and APS-C 24 Mpx are rather different in their light gathering capabilities

As to S/R - sorry, a typo - should read S/N, of course = my fingers seem to follow their own paths

EDIT: could you pls. tell us more about the "rainbow effect" you've mentioned? Are you perhaps far-sighted, or with some astigmatism?? I didn't ever see any errors which might be attributed as a rainbow in my OLED on N7,
