BR-3 Nikon rear-mount adapter ring for macro inversion on the Nikon F system, original Made in Japan, physical condition Very good and functional condition Tested and working.
Description from the seller
we are offering at auction this specific Nikon BR-3 accessory, a fundamental adapter ring for macro photography enthusiasts who use the Nikon F system and the technique of reversing the lens. this component is designed to be mounted on the rear mount of a lens when it is reversed using the BR-2 or BR-2A ring, a common practice to achieve magnification ratios higher than 1:1 without the use of expensive bellows.
The main function of the BR-3 is to transform the rear bayonet mount, which would remain exposed and vulnerable during inverted use, into a standard 52 mm thread. This feature is crucial because it allows the photographer to mount protective filters such as skylight or UV, or a lens hood, thereby protecting the rear lens and the delicate diaphragm coupling mechanisms from dust, accidental impacts, and stray light that could reduce the contrast of the final image.
observing the attached image, the specimen presents itself in very good aesthetic condition, with the black metal body showing minimal signs of wear and the steel flange of the bayonet clean and free of significant oxidation. this is an original object Made in Japan, solid and well constructed,
