This is a BEAUTIFUL Contax C mount 35mm lens kit including the lens caps, viewfinder, and storage bag.  It is in extremely good condition, the aperure blades open and close smoothly, focusing action is awesome as well.  No lens fungus or oil visible. 

I acquired this lens as part of a lot containing vintage camera gear at an estate sale and was absolutely floored when I found it in the box amongst the Canon and Kodak items.  The leather bag is in amazing condition, the lens is sharp and clear and clean, the viewfinder looks practically new... just one helluva rarity and one helluva find.   I don't have a C mount body to use this lens with so I'm putting up for sale in hopes it can find a good home and take some beautiful pics.
