Leica Summar 5cm 50mm f2 Leica L39 Screw Mount 1934 This is a masterpiece Leica lens that achieved an open aperture of f2 for the first time. Its compact, collapsible design and somewhat unique bokeh, which has a distinctive character, have made it increasingly popular in recent years. While aberrations remain in the periphery at the open aperture, the center boasts a resolution that rivals even the Summicron. 【Condition】 Appearance: Light scratches are visible on the lens barrel, but it is in good condition for its age. Optics: There is slight clouding, dust particles, and air bubbles from manufacturing when a strong light is shone through, but overall, the optics are clear. Summar lenses often have many scratches on the front element because it is soft, but this lens has few scratches and is in good condition. Aperture: There is no oil stain or stickiness on the aperture blades. Focus Ring: It rotates smoothly with a moderate torque, not too heavy or too light. 【Included Accessories】 Front cap, rear cap (The caps may differ slightly from those in the images) 【Shipping】 Shipped nationwide free of charge via Takkyubin (Japanese express delivery service). 【Returns】 Returns are accepted if there are any defects not described upon arrival.
