There continues to be a lot of talk concerning image brightness, mostly focusing on this or that survey. I am not qualified to be an arbiter here—nor do I want to be. But I would like to pour a cup of reason on the fire of debate.
There are two kinds of surveys at work here:
The individual or individuals making comments concerning looks, feel, size, weight, workings of the focus mechanism, hinge, eyecups, and their personal PERCEPTIONS of aberrations and performance.
And yet, so many of the people who DEMAND clinical DATA cling to the words of these people whose observations might be miles (multiply by 1.61 for my British and European friends) from clinical. And what makes you think their perceptions are any better than yours? ‘Because they made it into a magazine?
Are the opinions of these people worthwhile? Abso-darn-lutely! But, please realize their boundary of clinical knowledge does not offer the level of understanding so many clamor for and that those who really KNOW what is going on stay away from these bino forums in droves because they don’t want to get into peeing contests with the brash but clueless who rely on this or that survey from someone who saw a binocular more than once.
I am certainly not qualified to shed light on so many topics. But, while I did have an excellent BS meter, the needle has hit the stop so many times it’s gotten wrapped around.
People having a misaligned bino may say their bino won’t focus. They speak of brightness in terms of raw light TRANSMISSION when perceived brightness may be laid at the feet of CONTRAST. And what about RESOLUTION? You might have a dimmer image that is perceived to be brighter because the image is crisper due to an increase in RESOLUTION.
If you are not happy with your bino ... buy another. For, as one BRILLIANT, but incredibly HUMBLE, American optical wannabe has said:
Different test performed at different times with different subjects having different ranges of accommodation for different visual acuities under different conditions will produce different results.
Or, as Aristotle said back in 341 BC ... “Get a bloody grip and go out and look at some birds.” :cat:
Just a thought.

PS Get a photometer for Christmas. They're on the frozen food isle at Wal Mart.
