Very clean Canon Auto-Up V closeup attachment for Canon 50mm 1:1.2 LTM rangefinder lens, in the case. Made to work with late model Canon rangefinders from L series on (VT, VL, VI, P, 7, 7s etc.) but it would probably work with the earlier models as well. Attaches to the front of the lens. Glass is very clean. Allows focus between 20"-15"
