Thanks, I skimmed the link but a full read and analysis will have to wait for the morning. Follow up question: what do you suppose is the actual FOV of an OVF/EVF? I don't have either so I can't reference, though 90deg seems high. Also, only in the camera world of Bayer filters do they get to count red, green, and blue pixels separately. :] Hence my rounding up to 1MP EVF resolution... actually 0.8MP. I figure this is really more relevant than the 2.4MP claim.

It's a bit more complicated as the concentration of receptors in our eyes is actually heavier in the straight ahead position, particularly the cones which are responsible for identifying colours, which makes sense, as we don't need such hi-res peripheral vision

Isn't this all accounted for in the 0.3 arc-minute resolution? The article seemed to say that we did not really have the calculated number of megapixels but instead reach that resolution by scanning around.

"At any one moment, you actually do not perceive that many pixels, but your eye moves around the scene to see all the detail you want."

but really FOV doesn't matter so much as there is such a gulf between the acuity of the human eye and the paultry number of pixels in an EVF.

I don't expect the EVF (especially at the reduced 0.8MP rating) to be particularly close. The 150-250 range seemed high so I was curious to get a little deeper into how short the EVF is falling (from a mathematical resolution analysis perspective, that is...). So, FOV may not make a difference in whether the EVF is up to par or not, but going from 90 to 45 degrees would certainly reduce the difference by a factor of four, yes?

I know that most EVF convertees/devotees will probably say that all of this doesn't matter in the real world of image capture and if they're happy with that conclusion, so be it.

Two different things. Do you need to see every last detail your eye is able to resolve or is the other info more important? Certainly there is personal preference but likely also different scenarios push for different amounts of benefits each way. *shrug* To each their own, choice is nice.
