This 42mm slip-on plastic lens hood was made by FED primarily for use on its Industar-61LD lens.
But this lens hood also fits many Russian normal lenses with the 40.5mm filter thread, such as Jupiter-8 (all versions), Jupiter-3 (all versions), Jupiter-11 (all versions), Industar-26m, Industar-61, Industar-61LD and some others.
Please ask us if you are not sure about your lens. The lens hood fits on the outside surface of the filter ring.
The lens hood was made in the 1990's by the FED factory. It has been long discontinued since then, but a NOS (new old stock) lot was found by our suppliers in Ukraine.
The camera and lens are shown for illustration and are not included.
