## Long description

The Massa adapter ring SB639 is an intermediate converter designed for use with Nikon cameras to provide a mechanical interface between compatible lenses and camera bodies. This compact adapter ring enables mounting of lenses that would otherwise be incompatible or allows a small extension to achieve closer focusing distances for macro and close-up photography. Constructed for straightforward use in the field, the adapter maintains a low profile to preserve handling balance and does not include electronic contacts or optical elements.
Advantages
The adapter ring offers a simple, robust solution for adapting or extending compatible lenses on Nikon camera bodies without adding optical correction. It is lightweight and compact, making it easy to carry in a camera bag and quick to install. Because it functions as a purely mechanical interface, it preserves the original optical characteristics of the lens while permitting new lens–body combinations and slight increases in working distance useful for close-up work.
Suitable for
 Photographers who need to mount non-native or compatible lenses on Nikon camera bodies
 Macro and close-up photography where a small extension helps achieve closer focus
 Studio or on-location shoots requiring flexible lens combinations
 Users seeking a compact, mechanical adapter without electronic communication
Key specifications
 Type: Mechanical adapter / intermediate ring for Nikon cameras
 Function: Provides mechanical mounting or slight extension for lenses
 Construction: Solid metal or metal alloy body designed for durability (no optical elements)
 Weight and size: Compact and lightweight for portable use
 Compatibility: Designed to match the mount geometry of specified Nikon camera/lens combinations (verify fit with your equipment before purchase)
How to use
Attach the Massa adapter ring to the lens or camera body as indicated by the alignment marks, then mount the combined assembly to the complementary mount in the usual manner. Ensure that the adapter seats fully and the locking mechanisms engage to secure the connection. Because the adapter is mechanical only, autofocus and electronic aperture control may not be available; set aperture and focus manually as required. Inspect the mount interfaces for dust or debris before use to maintain a secure connection and protect lens and camera surfaces.
Usage recommendations
Confirm physical compatibility with your specific Nikon camera model and lens before use. For macro work, use the adapter as part of a workflow that includes manual focusing and careful exposure control. When carrying or storing the adapter, keep it capped or in a protective pouch to prevent dust ingress and preserve mount surfaces.
