World Minimum Nikon Silver-ring Filter
World Minimum Nikon Silver Filter
They are mini filters made by Nippon Kogaku. Some letters are engraved to the filter rim with very small print, to that should be surprised !! You can read the engraving as follows.
NIPPON KOGAKU JAPAN Y48
According to my long time researching, I think this is the smallest Nikon silver filter all over the world. The world minimum Nikon silver filter is not expensive if you find but also it is hard to find, and an unused filter is very difficult.
If you mount this small filter on your camera, you can understand ant's heart. I recommend this small filter to all digital poet and an Astro Boy.
