Interesting quality little lens from Poland. This is vintage all-metal (brass based) version with clean optics. M42 base mount but adjusted to reach infinity on Nikon with included thin adapter. There is no focusing but one can use in-adapter revolutions to reach about 2m distance. I will add a macro M42 ring, so you can use it also as close-up / macro lens. Looks great, gives splendid, sharp results. Camera not included. Shipping Worldwide: Signed For, Priority, Tracking. EU 5-10 days, Rest 3-4 weeks. EU buyers: to avoid currency conversion costs i can relist in EUR if desired.
