เรื่องราวของเลนส์
The Mamiya/Sekor 55mm f/1.8 was one of two standard kit lenses offered for Mamiya's TL/DTL series 35mm SLR cameras, spanning from the mid-1960s through the early 1970s. It sits within Mamiya's broader optical pedigree—a company that built its reputation on rugged, well-corrected glass, including the C330S TLR line referenced by one reviewer. Two barrel styles exist: earlier versions have bright trim rings, while later versions are painted black. The source of manufacture is typically attributed to Mamiya/Sekor, though there are reports of production by Tomioka, and the lens bears a strong physical resemblance to some Komine lenses of the same vintage. Contemporary reviews from Photography magazine in 1967 and 1968 (Arthur Palmer and Ron Spillman) praised its bench performance: excellent edge quality, outstanding contrast, negligible focus shift on stopping down, and only a minute degree of coma at the extreme edges. No established nickname or jargon term applies to this specific lens. Importantly, this non-SX version is confirmed non-radioactive—its typical Mamiya brown/yellow coating is NOT an indicator of radioactivity (though the larger f/1.4 sibling IS radioactive, and some SX versions are as well). Its cult following today rests on being an undervalued, cheap-but-characterful vintage standard lens that is sharp enough to be usable wide open on modern digital bodies, with 'bags of character' according to reviewers.
สรุป: The Mamiya/Sekor 55mm f/1.8 is a superb, undervalued vintage standard lens for photographers who want genuine character without sacrificing sharpness. It delivers outstanding contrast and detail—even wide open—alongside creamy bokeh and a subtle three-dimensional pop, all in a solid all-metal body. It suits portrait, travel, and general shooting, and it's an especially attractive choice for those who value the tactile, deliberate experience of manual focus and want a classic look straight out of the lens. Buyers seeking this specific rendering should confirm they're getting the non-SX, non-radioactive f/1.8 version.

รีวิวจากผู้ใช้
ข้อดี
- Exceptional sharpness and outstanding contrast, usable even wide open at f/1.8 on modern digital bodies
- Excellent value—widely considered undervalued for the character and quality it delivers
- Solid all-metal construction with a precise, no-play focus ring and pleasant, gently-clicked aperture ring
- Characterful vintage rendering with soft color transitions, natural contrast, and a subtle 3D pop
- Creamy, characterful bokeh wide open, well-suited to portraits
- This non-SX version is confirmed non-radioactive, unlike the f/1.4 sibling and some other variants
ข้อเสีย
- The focus ring can be quite stiff on some copies (though this can aid precise manual focusing)
- Single coating and vintage design mean flare handling and other traits are less refined than modern glass (specifics unknown from reviews)
เทคนิคการใช้
- Use focus peaking or careful manual focus; the stiff, precise focus ring rewards deliberate focusing and the lens gives a distinct 3D pop when focus is exactly nailed.
- Lean into the built-in contrast for punchy images, or expose for the shadows on film to soften the strong contrast if you prefer a gentler look.
- Pair with ISO 100–400 films for the classic look—ISO 100 for bright days and fine grain, ISO 400 for mixed and low light.
- There is negligible focus shift when stopping down, so you can compose and focus wide open and confidently stop down without refocusing.
