Oh, another good can of worms for the forum... ;-)
What Bill Cook says has some truth: Most people can't tell the difference between a lot of binoculars.
But the corollary is also true:
SOME people clearly CAN tell the difference between a lot of binoculars. And there are some of those folks on this forum.
Suppose this was a high end audio gear forum, and members were socially obligated to post the results of a hearing test. This would then give folks a yardstick by which to judge the merit of someone's opinion. So, here, it has been stated by some that by posting one's visual acuity, the relevance of your experience/opinion of the equipment may be better understood. It has also been stated on this forum that if one's vision is only 20/20 that one couldn't tell the difference between a $25 pair of binoculars and a far more expensive pair.
However, when I read Henry Links' well written posts, and see that he is willing to carry an enormous pair of bins out in the field to get what he's determined to be a very high quality view, I realize that I'm not willing to go that route. Then Tobias Mennie, who runs a respectable 'binocular porn' website, weighs in with some of the most irrationally biased remarks against gear that is well thought of by many on the forum (and regularly disparaged by a few). Opinions such as these make for interesting reading but regardless of those individual's visual acuity, there are other reasonable points of view, and choices for the individual, besides what a few have determined to be the best (or worst)....for them.
When I read Chuck's, Troubador's, and other's reviews, I find the greatest value in how they fit, feel, and perform in the field, as well as how they compare to other binoculars. The binocular is as much a mechanical device as it is an optical one. There are other attributes and factors that go into making an informed decision. Wearing glasses makes a huge difference in what is available for the individual. Throw in IPD specs, and the options get smaller and smaller. I appreciate and value the range of experiences and opinions folks post here, not just from folks that are 20/12 or less.
I dare say that if the supremely visually acute were the only folks on the forum that had anything of value to say, regarding the use and opinions on binoculars, this would be a pretty small group.
