On older bins with primitive or even no coatings, getting rid of ghosts was a much more difficult job and was not as easily achieved. If you get a vintage pair with little or no ghosting you can be sure it's a result of a very careful design.
On the other hand, some of the finest binoculars I own have ghosting but are otherwise wonderful instruments.
Fully agree. I own a vintage roof 8x56, long body and VERY truncated pupils, single coated from the brand PORST, japanese made for the german market. the bino is probably from the 70´s and provide some slight haze in the views. Why i kept it? because its ghosting and glare control is excellent, even better than the Carl Zeiss Jena. when i point to the moon the image is sharp and clean, moving around the moon its hard to see any kind of veiling or glare. While this is normal in a quality modern bino, i did not expect that from a -I assume- regular quality bino 40 years old.
P.S. after 8 years, just found the J number of this binocular: J-102. Any idea of the manufacturer?
