Rollei RIII Bayonet 43 to 58mm Filter Adapter.

This is a Rollei RIII Bayonet 43 to 58mm Filter Adapter designed for adapting filters from a smaller diameter (43mm) to fit lenses with a larger filter thread (58mm).

It allows photographers to use their existing collection of smaller filters on larger lens mounts, expanding the utility and versatility of their equipment.

The adapter is made of metal with a bayonet mount at one end and a 58mm threaded ring for attaching filters at the other.

In terms of condition, this adapter shows minimal wear; there are no visible scratches or dents, and the finish on both the metal parts and any glass elements remains consistent without notable cosmetic issues.

The adapter functions fully as intended.
