เรื่องราวของเลนส์

The Vivitar 28mm f/2 was one of many 28mm wide-angles sold under the Vivitar name, which contracted out lens production to a range of Japanese optical houses including Tokina, Cosina, Kino Precision (Kiron), and Komine. This particular fast f/2 version was made by Kino Optical (Kiron) and is identified by serial numbers beginning with 22xxxxx (the Komine builds carry 28xxxxx serials, Cosinas 9xxxx, and Tokinas 17xxx). The only established community term tied to these lenses is 'Kiron,' the Kino Precision house brand that denotes the maker rather than a nickname. According to the reviews, there are two notable production eras: earlier examples featured a long 260-degree focus throw, a double helicoid with floating elements (the front and rear optical units moving differently), and an 'AUTO WIDE ANGLE' nameplate, while later versions used a shorter 90-degree throw and 'MC WIDE ANGLE' nameplates. The lens earned a following among vintage shooters for its combination of a genuinely fast f/2 aperture in a wide-angle, strong build quality, and excellent handling, all at an affordable price point. No swirl, glow, or invented nickname is supported by the reviews.

สรุป: The Vivitar (Kiron 22xxxxx) 28mm f/2 is a well-regarded, affordable fast wide-angle that reviewers praise for sharpness, bokeh, handling, and value, earning a 93% recommendation rate. It suits vintage-lens enthusiasts who want a bright 28mm with solid build and good rendering, provided they check for the common oily-iris problem before buying.

รีวิวจากผู้ใช้

ข้อดี
  • The fast f/2 aperture, unusually bright for a wide-angle prime of this era
  • Excellent handling, one of the highest-rated attributes (8.7)
  • Strong value for money (rated 8.8), with an average price around $82
  • Good sharpness and pleasing bokeh (8.3 and 8.4 respectively)
  • 93% of reviewers recommend the lens, with an average user rating of 8.50
  • Solid build quality typical of Kiron (Kino Precision) construction
  • Availability of a floating-element design on the earlier double-helicoid versions
ข้อเสีย
  • Kiron 22xxxxx versions are known to be prone to oily/sticky iris blades
  • Confusing variant landscape, with many different makers using the Vivitar 28mm designation
เทคนิคการใช้
  • If purchasing an example with sluggish aperture blades, budget for a CLA; a repair article for the oily iris issue exists per the reviews
  • Identify the version by focus throw and nameplate to know whether you have the floating-element double-helicoid design
