    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    Precisely …… but also true.

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    This is my experience. It is heresy to say it, but the SF made my EL SV look “muddy” in direct comparison.

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    I found mine to be really annoying, until I figured out not to jamb them so far into my eye sockets.

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    All threads do so, because each of us sees with a different pair of eyes, coupled with a (presumably) unique brain with its own signal and image processing. There is absolutely no way to convey what we see to another human being. We can all agree that light with a wavelength of 700 nm is...

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    Evidently. If there are no superimposed emission lines, and the phosphor has the right distribution, then I guess we might call it “neutral”. I didn’t realize we were discussing artificial light, I thought the discussion was about transmission of the light reflected into binoculars by birds...

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    No it’s not, it has very strong Hg lines on a continuous background from the phosphor, last time I looked, and it is generally regarded as “cold”. (unless I have it confused with something else)

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    Color neutrality is implicit in color accuracy, so there is no need for “both“, and without color neutrality, you can‘t have color accuracy anyway. I think having two terms just adds another layer of confusion to an already muddled understanding.

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    Since the absence of color neutrality (presence of a bias) affects color accuracy, it seems to me to be a distinction without a difference in the real world.

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    I think we’re saying the same thing ….. you’re just using more words. :)

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    Some seem to have difficulty getting their heads around the difference between objective and subjective. Some do not even believe that there is a difference, because they are convinced that what they see must be real and correct. It may not be.

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    Exactly, and the farther we wander off the Path of Objectivity, the more we wade into the Swamp of Subjectivity. If it weren’t for this, the present forum probably would collapse, since so many of our discussions are of the “I see it/I don’t” nature.

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    Color is indeed a percept, that is my point. We can measure the Na lines all day at 5890/5896 Å, but no human has any clue what those lines actually look like to any other human.

    “Measuring instruments” are generally regarded as objective …… observers are certainly not.

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    That is neither my understanding, nor my experience. As we age, our lenses become yellowed, thereby filtering out the violet end of the spectrum. Perhaps I didn’t read your comment correctly.

    I learned a new word. :)

    One small niggle ……. I believe it is the brain which “adjusts”.

    Do the owners of both Zeiss SF and Swarovski EL/NL feel they are uncomfortable for the different color cast?

    A Zeiss SF 8X32 has been my only binocular since December 2020. At no time have I seen, or been annoyed by any “greenish” cast whatsoever. (or any other color) I see pure and blinding whites. I have undergone bilateral cataract surgery with implants supposedly containing ultraviolet...
