Nikon Nikkor-P Auto 10.5cm F/2.5 Nippon Kogaku Lens (USED)

The Nikon Nikkor-P Auto 10.5cm f/2.5 is not just another portrait lens; it is the lens that established Nikon’s reputation for optical supremacy. Often called the "Sonnar version," this specific 10.5cm (105mm) model is the direct descendant of the rangefinder lens that famously stunned Western photojournalists during the Korean War.

If you are looking for a lens that combines professional build quality with a unique, vintage rendering that modern lenses can't replicate, this "Nippon Kogaku" classic is the gold standard.

Before 1971, Nikon used a 5-element in 3-group Sonnar-type design for the 105mm f/2.5. This differs from the later "Gauss" versions found in AI and AI-S lenses.

• The "Sonnar Glow": Wide open at f/2.5, this lens has a signature "glow"—a subtle softness that is incredibly flattering for skin tones, while still maintaining high central resolution.

• Character-Rich Bokeh: The Sonnar design produces a more traditional, painterly background blur that many photographers prefer for fine-art portraiture over the clinical perfection of modern optics.

• Transition of Focus: It features a very smooth "roll-off" from the sharp focus area to the out-of-focus background, giving your images a natural, three-dimensional depth.
