As a general rule of thumb, German binoculars are considered the most sought after, followed by American, English; and French, which are typically good quality but are more common unless of unusual design. Some of the best names in Japanese optics of WWII or before are often of very high quality.
Some binoculars are center focus, with one central wheel that focuses both sides at once. Individual focus binoculars are adjusted by rotating each eyepiece. Each style is desired by different collectors. Very large binoculars are always sought after. Most binoculars are numbered according to their magnifying power and the diameter of the objective in mm. 12 x 30 optics magnify twelve times and have 30 mm objectives. Some of the older Paris made binoculars lack this information. Personally, I love the old Parisian binoculars, these classic heirlooms are usually quite affordable, fun to use and are a great product for tabletop and bookshelf décor.
