Special Close Focus 8x30 E - for 1.5 m to 6 m!
I came across this while doing some research on Nikon’s Porro prism binoculars
It’s from a Japanese sales site: https://item.mercari.com/jp/m300442...bR7sKpEWz8pXHoWHi6WxqpoA-NFnDYRXpPju1K6tFt1NW
It appears to be a standard multicoated 8x30 E (serial number #440,358), modified for specialised close range use
The text suggests it’s for industrial use, to read glass covered instrument dials
Besides modification for closer focus, there would also need to be alteration to the collimation to align the two images at such close range
The additional markings on the left hand prism plate are clearly professionally done (so by Nikon, as opposed to an after sale conversion?)
I couldn’t find any other references to such a model
Perhaps some Nikonista has more information?
