EdZ...
How right you are. I posted the previous link because of its diversity of opinions about the ED/nonED versions of a specific model. I think discussion and different opinions make online forums worth the time and effort to participate and keep up with the topics.
. . .
Now, regarding the ED/nonED question, I think we cannot really do the topic justice without entering the discussion of color sensitivity among various observers. Simply put, how much do differences of color sensitivity by individual observers affect the decision to purchase an ED or nonED model? If the observer's eyes are sensitive to one or more colors, maybe the ED binocular may be worth the premium price. On the other hand, if the observer has limited sensitivity to colors, the nonED binocular may see just as much as the ED model.
EdZ, I know you discussed color sensitivity differences among observers. However, here is a link from another forum with links to medical research that also discuss the many nuances of color sensitivity. I direct any interested reader to the links in my first post of the thread in the link below--(1) How we see colors
(2) Intertwining of color sensitivity with the other senses
(3) Possible gender differences in color sensitivity. Here is the link: What determines our color sensitivity as looking through bins? .
The link also discusses brand manufacturer bias toward specific colors, as well as atmospheric influences upon brand manufacturer's color rendering. Some of the participants in the link have actually done tests (with photos) of brand manufacturing bias.
