Chinon Angle Finder brand_Slik but I'm not CanonThe Chinon Angle Finder slip onto the viewfinder of compatible cameras and provides a rotating, focusable view of the groundglass. Ideal for copystand or precision macro work, this angle finder will fit most Chinon SLR cameras with rectangular viewfinders; may fit other cameras, but no guarantees (it's not quite right for a Pentax Spotmatic K1000 finder). In excellent condition, though the rubber eyecup is long gone. Includes box.
