Reverse mount adapters for Ultra-Micro-Nikkor

For macro photography

These dedicated adapters are longer than the ones for enlarging lenses, in order to fit properly the recessed front filter thread on the Ultra-Micro-Nikkor lenses. They are not recommended for use with enlarging lenses.

Long 40.5mm x 0.5 reverse mount adapter

Available with M39 (LTM) mount, M42 mount or T2 mount. Available in aluminum or brass.

For Ultra-Micro-Nikkor 28mm.
The 40.5mm thread is 5mm long, in order to fit properly the recessed front filter thread on the Ultra-Micro-Nikkor lenses.
Not recommended for use with enlarging lenses, as on enlarging lenses the longer adapter may jam onto the metal ring of the front element.

A solid adapter, made in aluminum, with 5mm long 40.5mm x 0.5 male thread on front to fit the lens front filter thread. Available with male M39 Leica thread mount, M42 (42mm x 1) thread mount or T2 (42mm x 0.75) thread mount on the other end.
