Vivitar Vivitar 70-150mm f3.8 Heritage

เรื่องราวของเลนส์

The Vivitar 70-150mm f3.8 is a close/macro focusing zoom manufactured by Kino Optical (Kiron) for Vivitar, identifiable by its 22xxxx serial number prefix. Vivitar itself was a brand that commissioned lenses from various Japanese optical makers; this particular design came from Kino Optical, whose lenses are widely respected under the 'Kiron' name (Kino also marketed a version of this lens as the Kiron 70-150mm f4). The reviews note two distinct versions exist: an older two-ring (two-touch) variant with a separate dedicated macro mode at 70mm, and a one-ring push-pull (pump-action) variant that focuses closely at all focal lengths. It was commonly sold in Pentax K and M42 mounts (and other mounts of the era, including Minolta and Nikon), often bundled with a dedicated 2x Vivitar teleconverter. Note that there is a completely separate Tokina-made Vivitar 70-150mm with a 37xxxx serial that should not be confused with this Kiron-made optic. It enjoys a modest cult following among budget-minded vintage shooters for being a genuinely good, inexpensive macro-capable zoom. The only established piece of jargon tied to it is the 'Kiron' maker attribution, which vintage enthusiasts use as a mark of quality.

สรุป: The Vivitar (Kiron) 70-150mm f3.8 is a budget-friendly, macro-capable telephoto zoom best suited to vintage shooters who want a versatile, well-built manual-focus lens without spending much. It shines at its close-focusing end, delivering genuinely sharp results, and rewards patience in learning its controls. It is not a bokeh-first character lens, but for the money it is a highly recommended practical performer.

ความคิดเห็นแตกต่างกัน: บางคนกล่าวว่าไม่ได้เรียบเนียนเป็นพิเศษ แต่บางคนระบุว่าความคลาดสี (CA) และการเกิดขอบสี (fringing) ถูกควบคุมได้ดีและแทบไม่สังเกตเห็น

ความคม (เปิดสุด)

ความคมชัดโดยรวมอยู่ในระดับดีพอสมควร โดยเฉพาะโดดเด่นเป็นพิเศษเมื่อโฟกัสใกล้สุดที่ 70 มม. และในช่วงมาโคร

รีวิวจากผู้ใช้

ข้อดี

Excellent value for money — average price around $27.92 with an 83% recommendation rate, making it a very good macro lens for the budget minded photographer
Very sharp at the 70mm/close-focusing end, especially useful in macro range (even better with an added extension tube)
Manual focusing is described as 'a joy'
Well-controlled chromatic aberration and barely noticeable bokeh fringing on well-regarded samples
Solid build quality ('well built')
Compact and handy for a zoom of its type

ข้อเสีย

Learning curve for operating the focus and focal length controls — described as 'not very intuitive'
Bokeh is not particularly smooth according to some reviewers
One reviewer flatly did not recommend it, rating it 4 and citing the unintuitive handling

เทคนิคการใช้

Use it at the 70mm close-focusing end for the sharpest results
Add a 25mm extension tube at 70mm close-focus for even greater sharpness and magnification in the macro range
Take time to learn the two-ring or push-pull controls, as handling is not intuitive at first
If mounting on a DSLR, verify the aperture lever guard is not the overlarge type that blocks mounting
