This is the entirety of my RF Nikon equipment. Came to RF very late after getting the Z6. Nothing collectible here, but good fun. Forgot to include the bellows 13.5 cm.
My newest is the 3.5cm 2.5, after reading very positive reviews about it, my copy is rather disappointing. The lens is clean, clear, never apart, and good looking but my copy has ugly sides until f/8, then it suddenly sings. Jekyll and Hyde.
