Nikon Nikkor-Q 13.5cm f/3.5 (LTM) - Leica M39 Mount

The Nikkor-Q 13.5cm f/3.5 is a vintage telephoto lens produced for Leica Thread Mount (LTM/M39) cameras. This lens is a significant piece of Nikon's early history, offering a Sonnar-type optical design that delivers classic rendering with a distinctive character. It is primarily used by collectors and film photographers using rangefinder systems or adapted to modern mirrorless bodies for its unique vintage look. Potential buyers should inspect the heavy chrome-on-brass barrel for significant brassing or dents. SDS technicians pay close attention to the internal optics, as lenses of this era are prone to internal haze and cleaning marks on the soft coatings. The long focus throw should be smooth without flat spots in the lubricant, and the aperture blades should be free of oil to ensure consistent operation.
