Of course this is unrealistic.It appears to me that how we resolve and what we resolve is a function of two variables, our visual system and the binocular itself.   The latter is the constant. even with microscopic differences.  But billions of humans with their own set of eyes and facial features are all uniquely different.  One of my eyes sees color differently from the other, and one "resolves" a wee bit better.  This in itself is not unusual.  But we must be driving the optical engineers insane trying to satisfy the whims and caprice of human beings, not to mention one another as we share our "findings" with each other.As a young lad with out the pot and window to do you-know-what, an old retired navy chief gave me a beat up old pair of Zeiss 7x50 IF binoculars.  This is the story he told me.  Zeiss supplied many of these binoculars to the United States Navy years before WW2 began.  As they were phased out by B&L binoculars, these became surplus, and that is how he acquired him.He knew I was interested in looking at birds and didn't possess any binoculars at all.  I still have them and take them out of the dried out old, black leather case for a quick peek now and then.  Guess what? They are still in collimation.  And though uncoated, they render a very good picture absent the bright colors seen in today's binoculars.   I have tried to date them from old catalogs and estimate they were made in the late 1920s or early 1930s.  Still useful.  No fungus at all.  On a black and white resolution chart they hold their own with any modern 7x50.  Or are my own lying eyes deceiving me?JohnJohn</blockquote>
