Overview: The Asahi Super-Takumar 105mm f/2.8 Lens
The Asahi Super-Takumar 105mm f/2.8 is one of those compact telephoto primes that quietly earns a permanent spot in many photographers’ bags. Built for the classic M42 screw mount, it offers a flattering 105mm focal length and a reasonably bright f/2.8 maximum aperture, wrapped in a solid, all-metal body that feels like it could outlive the camera you mount it on.
On modern mirrorless cameras, this lens transforms into a characterful portrait and detail tool. It balances sharpness with a gentle, organic rendering that many digital-era lenses struggle to match. Whether you shoot portraits, street details, or cinematic video, the Super-Takumar 105mm brings a distinctive look that feels both timeless and intentional.
The first time you pick up an all-metal Takumar, the focus ring often surprises you. It turns with a slow, damped resistance—perfectly smooth, never loose—like a finely tuned mechanical watch, inviting you to focus with care instead of haste.
Historical Background
The Super-Takumar series was produced by Asahi Optical Co. for its early Pentax cameras, at a time when the industry was refining lens coatings and mechanical design. The 105mm f/2.8 emerged as a compact telephoto option for photographers who wanted more reach than a 50mm, but in a smaller, lighter package than the typical 135mm lenses of the era.
Its M42 screw mount made it broadly compatible across many camera brands of the time, and that same simplicity is what makes it so adaptable to modern digital bodies today. Decades after its introduction, the 105mm f/2.8 is still in demand for its reliable build and classic rendering, especially among photographers who value sustainable, second-hand gear.

Rendering and bokeh
The Super-Takumar 105mm f/2.8 is known for its pleasing, slightly soft-edged rendering at wide apertures and strong central sharpness when stopped down. The bokeh is typically smooth and controlled, with backgrounds melting away in portraits, product shots, and tight details. Contrast is moderate out of camera, which suits both black-and-white work and color grading in post.
Flare is generally well-managed for its age, but like most vintage optics, it can show creative ghosting and veiling flare when shot directly into strong light. This can be a feature rather than a flaw, especially for atmospheric portraits and video, as long as you know how to control it.
Modern-Day Use and Creative Applications
Adapting to digital cameras
With a basic M42 adapter, the Super-Takumar 105mm f/2.8 works beautifully on most modern mirrorless systems. Once mounted, enable tools like focus peaking or magnification to make precise manual focusing much easier, especially at f/2.8.
- Attach M42 adapter securely.
- Enable focus magnification or peaking.
- Use lens hood to control flare.
- Experiment with open aperture portraits.
- Try de-clicking aperture ring for filmmaking.
Portraits, details, and video
At 105mm, this lens is a natural for portraits, offering flattering compression and enough working distance for candid, relaxed expressions. It also excels at tight detail work—flowers, food, textures, and product photos—where its rendering adds a touch of vintage charm without sacrificing too much sharpness.
For video, the combination of a smooth focus ring and gentle depth-of-field transitions gives a cinematic feel that many modern autofocus lenses lack. With practice, you can perform controlled focus pulls and create sequences that feel crafted rather than clinical.
Buying a Second-Hand Super-Takumar 105mm f/2.8
What to inspect before you buy
Because these lenses are decades old, condition varies widely. A careful inspection helps you pick a copy that will perform well for years to come.
- Ensure smooth focusing ring movement.
- Confirm aperture blades return promptly.
- Look through the lens under light for internal haze.
- Avoid fog, mold, or misaligned elements.
- Verify mount threads are clean.
Cosmetic wear is normal on a lens of this age, but deep dents, separation in the glass, or oily aperture blades can impact performance. When buying online, look for clear photos and honest descriptions from sellers who test their gear.
Why buy second-hand from a specialist
Choosing a second-hand Super-Takumar 105mm f/2.8 is not only budget-friendly but also more sustainable than buying new. Reusing classic lenses keeps high-quality glass in circulation and reduces the demand for newly manufactured gear. Shops that specialize in used equipment typically test focusing, aperture, and optical clarity, so you know what you are getting before it lands on your camera.
If you are building out a full kit, consider combining this 105mm with other lenses from a vintage lens collection, or pairing it with compatible photography accessories like M42 adapters, hoods, and cases for a complete, ready-to-shoot setup.
Conclusion: Why This Takumar Still Matters
The Asahi Super-Takumar 105mm f/2.8 sits at a sweet spot: compact but telephoto, sharp but forgiving, vintage yet fully usable on today’s cameras. Its all-metal construction and distinctive rendering make it more than just an old lens—it becomes a creative tool that invites slower, more thoughtful photography.
For photographers and filmmakers who enjoy manual focus, appreciate sustainable gear choices, and want a unique visual signature, this Takumar still matters. It is a small piece of optical history that can add real character to modern digital workflows, one carefully focused frame at a time.
