Obviously, a matter of opinion(s),
some held strongly. But the some
surprisingly great ones I have run across:
7x35 , 10 degree "Town & Country",
sometimes made for "King Korn" (!),
when made by JB3/JB4 (on the hinge, means "Toei Kogaku")
Of all the 7x35 10ds, these are the richest contrast
and highest contrast I have found. The propietary
70-deg afov eyepieces varied a lot, but Toei K. had the best..
I actually prefer these to my 8x32 Diamondbacks...
The contrast is finer.
Tasco "World Class Plus", in 7x50 or 10x50...
wow.....a few cuts above the rest.
A modern revisiting (multicoated, BAK4, etc)
of the Mirador line (made at JB4)...
There is a catch: sticky coating on the shoulders of
the binoculars. I knocked that off by de-polymerizing
with lye oven cleaner (and gloves/rags!)...
Adams Precision 7x35s:
There many clones of the B&L Zephyr /
Bushnell Featherweight /
7x35 "Lightweight" clones, but these top them all.
Very rare though.
Stellar <KOC> 8x30s..
Very sharp, even when the image is blown up.
Very fine polish on optics.
We're getting pretty far back in time, though..
...more likely to need a thorough cleaning.
prime contractor JB7, Nippon Kogaku
"High Power" binocs...(even named on 7x50s)..
...very high detail+polish, but very old
Limer 7x35s, 393ft (7.5 deg)
...another stand-out JB4..
The supreme ones are peppered among many others....
There are some better makers (JB4 Toei Kogaku is my favorite)..
JB65 can be remarkable in ordinary-looking binocs.
Most Japanese makers produced high, medium, and low grade..
Mid-50s was the best, but often the binocs are pretty beat and need attention.
60s were still great, with brands at photo shops being special,
like Scope, Kassnar...
Over the years, Bushnell drifted from best to really mixed quality,
as US inflation kicked in, 70s--80s. Even today, the "Falcon"
continues the lots-of-plastic and/or uncoated innards scheme that
began with the "Ensign".
