SMC Pentax-M 135mm f/3.5 Telephoto Prime Lens - Good Condition | Ultra-Compact Manual Focus Telephoto Featuring Super-Multi-Coating and Built-In Retractable Lens Hood

Introductory Paragraph The SMC Pentax-M 135mm f/3.5 is an incredibly compact, fully manual telephoto prime lens masterfully crafted by Asahi Optical Co. in Japan. Celebrated for its remarkably slim barrel design and legendary Super-Multi-Coating (SMC) optics, it delivers exceptional color fidelity, rich contrast, and resistance to flare. Utilizing the timeless, rugged Pentax K-mount system, this scannable Pentax lens is highly favored by analog film purists and modern digital mirrorless cinematographers seeking a lightweight, pocket-sized telephoto portrait powerhouse.

Key Features

• Premium Super-Multi-Coating (SMC) optical glass layer treatment, maximizing light transmission while completely eliminating internal ghosting and flare.

• Ultra-compact telephoto prime lens barrel architecture, maintaining a remarkably slim, pocketable footprint that balances perfectly on compact camera bodies.

• True 135mm telephoto focal perspective field, compressing background elements beautifully to yield elegant, professional portraits and tight street frames.

• Built-in retractable telescoping metal lens hood design, extending smoothly on command to shield the front optical glass element from stray sunlight.

• Tactile dampened manual focus tracking helicoid, offering an incredibly smooth, precise rotational throw for pinpoint manual focus accuracy.

• Crisp 6-blade circular aperture diaphragm system, generating a soft, painterly background blur and smooth out-of-focus bokeh highlights.

• Native Pentax K-mount mechanical geometry, locking firmly onto vintage film SLRs or adapting effortlessly to modern digital mirrorless sensors.

Condition Report Good condition. Body: Standard light use, showing typical fine cosmetic scuffs on the outer aluminum barrel and faint wear along the knurled metal focus ridges. The rear mount tabs are clean and seat firmly. Sensor/Optics:Lens elements are bright and clear. The glass is completely free from internal fungus, heavy haze, optical separation, or deep glass scratches. Mechanics/Electronics: Fully operational. The manual focus ring turns with a silky, uniform feel, the built-in hood glides smoothly, the aperture ring clicks cleanly at every stop, and the aperture blades are dry and oil-free.

Specialist Note "The Pentax-M 135mm f/3.5 is a true marvel of miniature optical engineering. While most vintage 135mm lenses are heavy and cumbersome, Pentax managed to shrink this prime down to the size of a standard 50mm lens. Don't let its small size fool you—its five-element design is biting sharp even wide open at f/3.5, and that world-famous SMC coating gives your images a gorgeous, cinematic contrast with deep, rich colors. Complete with a built-in retractable hood, it's a completely transparent, satisfying everyday telephoto."
