Pentax (Takumar) Pentax Takumar 135mm f3.5 Heritage

เรื่องราวของเลนส์

The S-M-C/Super-Takumar 135mm f/3.5 was produced by Asahi Optical Co. between 1965 and 1975 as a compact, manual-focus telephoto prime for full-frame 35mm film cameras using the M42 screw mount. It exists in two main iterations: the earlier Super-Takumar and the later Super-Multi-Coated (S-M-C) Takumar, the latter introducing Asahi's 7-layer SMC coatings and open-aperture metering compatibility with the Spotmatic F, ES, and ESII bodies. Both versions share a 4-element/4-group optical formula. No specific nickname or community jargon is evidenced in the reviews. Its cult following stems not from any exotic optical trickery but from its excellent all-metal build, buttery-smooth long-throw focus ring, characteristic 'vintage color rendering à la Takumar,' and remarkably low price, making it a beloved budget entry point for vintage lens enthusiasts and adapters to digital bodies. For many, like one reviewer, it was the very first vintage lens they ever acquired.

สรุป: The Takumar 135mm f/3.5 is a characterful, beautifully built budget telephoto ideal for portraits, landscapes, and vintage lens lovers who value tactile handling and warm Takumar color over speed and clinical sharpness. It won't dazzle with dramatic optical effects, and its modest f/3.5 aperture limits low-light and separation potential, but for the money it delivers pleasing, classic rendering and a genuinely enjoyable shooting experience—best paired with a stabilized digital body and the original hood.

คาแรกเตอร์ของภาพ

โบเก้

ให้โบเก้ (bokeh) แบบคลาสสิก 'pulpy' ที่นุ่มเนียนและเหนือกว่าเลนส์คิท แต่รูรับแสงสูงสุดที่ f/3.5 จะจำกัดการแยกตัวของแบบจากฉากหลัง

โทนสี

ให้โทนสีอุ่นและคลาสสิก — การถ่ายทอดสีวินเทจแบบ Takumar — เป็นเอกลักษณ์ที่โดดเด่นและเป็นที่ชื่นชอบ

ความคม (เปิดสุด)

ให้คุณภาพดีตั้งแต่เปิดรูรับแสงกว้างสุด และคมขึ้นที่ f/5.6; คมพอเมื่อจำเป็น แต่ไม่คมเท่าเวอร์ชันที่เร็วกว่า (f/2.5)

แฟลร์

แม้เลนส์จะมีการเคลือบหลายชั้น ก็ยังมีแนวโน้มเกิดแฟลร์ได้ การเคลือบแบบ SMC ช่วยลดแสงแฟลร์และเงาสะท้อนได้บ้าง แต่ไม่สามารถขจัดสิ่งรบกวนทางแสงได้ทั้งหมด ดังนั้นจึงแนะนำให้ใช้ฮูดเลนส์

รีวิวจากผู้ใช้

ข้อดี

Excellent all-metal build quality typical of Takumar lenses, consistently praised as never disappointing.
Long-throw, smooth focus ring that aids accurate manual focusing.
Characteristic warm vintage Takumar color rendering.
Smooth, 'pulpy' classic bokeh that outperforms any kit lens.
Extremely budget-friendly price, averaging around $45.
6-bladed sun stars when stopped down for long-exposure work.
135mm is a great focal length for portraits on full frame with little distortion.

ข้อเสีย

The f/3.5 maximum aperture is not 'fast' and limits low-light and shallow-DOF use.
Prone to flare and artifacts in backlit situations despite multi-coating.
Chromatic aberration visible in extreme high-contrast/backlit scenes.
Front-heavy balance that can cause uneven framing and vibration blur, especially on film SLRs.
Difficult to focus on moving subjects due to the long focus throw.
Image quality described as competent but 'not something overly special.'

เทคนิคการใช้

Use a hood or avoid shooting directly into bright light to minimize flare and artifacts.
Adapt to a digital body with IBIS to counter the front-heavy vibration and capture sharp images.
Shoot RAW and post-process to tame chromatic aberration in high-contrast scenes.
Stop down to f/5.6 for improved sharpness, or shoot wide open at f/3.5 for the smoothest bokeh.
Stop down and use long exposures to render pleasing 6-bladed sun stars from point light sources.
When adapting via M42-to-EOS or similar adapters, remember the lens works only in Manual aperture mode.
Dial in exposure compensation if shooting JPEG stopped down, as some bodies over-expose progressively.
