    Chronology of focus wheel styles & eye cup styles?

    Yes. Used to be S&A Boston. They used some French made binos

    What view of a bird do you need to consider it "Checked/Ticked" off list?

    Great input so far. For me, other than for folks with vision handicap, it would have to be seen. It is called " bird WATCHING " after all.

    Hartmann Compact collimation

    I second that, remove beauty ring first always before coming to conclusions. If still no other ring then perhaps find out if there are prism tilt screws first before messing with those rings.

    Chronology of focus wheel styles & eye cup styles?

    I bought because of the stellar reviews on these types of forums. And I like a good vintage bino. Mechanically it was nice, optically nice, just not fond of the color rendering.

    Glad it worked for you. I expected to get a good price. Sold for a measly $38. Guess not that desirable anymore.

    Has build quality diminished? Optics are superb but the housing, focus, . . .

    The issue I see with binoculars comparisons of quality is that It hasn't been that many years that you were holding a miltary grade bino or a Zeiss or Japanese JB unit, or maybe still use those occasionally. What other product out there today can you get nearly identical performance out of the...

    Chronology of focus wheel styles & eye cup styles?

    Thanks for the additional information. I did a side by side of my 804R, Triton, Saratoga and Nighthawk, all rendered unfavorable compared to naked eye and compared to other binoculars of similar vintage. It may be just my preference, but I at least would like it to match my naked eye...

    Great reminder of that thread Ed. I've run across it before. Not to diverge from Charlie's question, buy I recently sold my 804R. Didn't get the WOW out of it I was expecting for such a revered instrument. I've found all the Swifts I've owned tend to render color bluish gray, so have sold.

    If you go over to miniaturebinoculars.com, I think catalog #7 mfgs starting with letters O to T, there are several Swift catalogs in pdf on there. Maybe you can recognize the models you have and it will give you clue to the years. Good luck.

    "Thue-Morse is fascinating, compared to my/our search for ASCII character values. Even some sports are thinking of adopting it." Hurts my head reading about that, and I took some C++ classes....... oh well, "here birdie birdie birdie...., nice birdie..."

    Stopping down a binocular

    If you can design it either digitally or drawing it, a cap with precise holes in it is perfect for 3D printing. There are many places online that with take your design and print you one-off samples pretty cheap. Try out different diameters that way.

    Chronology of focus wheel styles & eye cup styles?

    I can only imagine a Swift collector could give you some insight. Curious your interest in wanting to know this. Swift , like most all the others were distributors of Japanese made binoculars. If you bought enough, you could put your name on it. I'm not sure if Swift stuck with the same JB mfg...

    I only knew you had some clever reason for the binary. I see it's just " i " I read something wrong online about its meaning as i love u, but glad you got a laugh. See, this is why I should stick to reading newspapers and wrenching on binoculars.....alone......in the dark.....😭

    Dear " I love you", ( clever with the binary there) , it sounds like you need to get to a store and try out some binos that fit your ipd ( eye distance apart) also, doing you have any color rendering problems with your eye sight? Do you have other birders in your area you can try their binos...

    Share your stories of being harassed/threatened while out birding.

    " Are you lost...." is that a U.K. passive way to say. " What the H are you doing in my neighborhood "? It's usually the faux rich who think they are special behind their gates. They can't get respect, so they have to buy it, and hide behind walls. Don't be intimidated. Feel sorry for them...

    Chk year 2006 Birdforum thread called. "Evolution of Trinovid coatings" . Quite a discussion on Leica serial numbers and coatings. Maybe some help there.

    Old versus New

    I have a 7x21, 8x30, 10x40, 12x50 reverse skeletons . They are bright, crisp to edges. But keep them out of dust and moisture ! Plus drop them and you'll cry at the damage. The biggest I know of is 18x50. See miniature binoculars website. Tenex you make some good observations. We put up with...

    Old versus New

    Not sure I buy that. I have some very small reverse porros that are shorter and optically better than an equivalent roof of the same era. I'm still guessing it was only for water/dust resistance. Binos were driven by military needs back then. Probably had the biggest influence.

    Recommend 6x binocular?

    I think most of the modern rubber covered binos seem like toys. Take the rubber of a new Nikon or Pentax. Watch your face sag as you see molded plastic everything that cost about 5 cents to make.

    Old versus New

    Yeah, I can see some going for that, but I find porros, especially B&L style(vs zeiss) easier to hold as your hands are further apart and you can grip fully around. On my roofs , my finger tips and thumbs knock into each other. I have to stagger my hands or not grip fully. Feels awkward...
