Nikon Nikon 105mm f2.5 Heritage

เรื่องราวของเลนส์

The Nikon 105mm f/2.5 is one of the most storied telephoto primes ever made. Nikon produced a 105mm fast prime version from 1959 to 2005, spanning the early Nikkor-P (a five-element design) through the AI-S generation reviewed here. It was popular with photographers, especially photojournalists, from the late 1950s to the 1990s, before autofocus 80-200mm f/2.8 and later 70-200mm f/2.8 zooms became the pro standard and pushed it out of working bags. Its legendary status is cemented by history: Steve McCurry used a 105mm f/2.5 for his iconic 'Afghan Girl' shot that graced the June 1985 cover of National Geographic. The lens developed a cult following partly because it was, as one reviewer put it, 'known for its bokeh before most people even knew bokeh had a name.' People love it for its compact, well-made all-metal construction, its rewarding manual-focus experience that 'makes you think, be smart,' and rendering that reviewers describe as clinically sharp yet possessing a genuine character wide open. No established nickname is evidenced in these reviews.

สรุป: The Nikon 105mm f/2.5 is a definitive classic portrait and short-telephoto lens for photographers who want modern-grade sharpness paired with genuinely smooth, characterful bokeh. Compact, robust, historically significant, and widely available at affordable prices, it's a no-brainer for anyone comfortable with manual focus who wants reach beyond 50mm with beautiful subject separation.

โบเก้

จุดแข็งที่โดดเด่นคือโบเก้ (bokeh) ที่ให้ลักษณะ 'มหัศจรรย์' เนียนนุ่ม พร้อมการไล่ความเบลอแบบขอบนุ่ม (feathered falloff) ทั้งด้านหน้าและด้านหลังของตัวแบบ โดยไม่เกิดเอฟเฟกต์โบเก้แบบหมุน (swirl) หรือแบบเป็นฟอง (bubble artifacts)

ความคม (เปิดสุด)

ให้ความคมชัดสูงเทียบเท่าออปติกสมัยใหม่ — ใช้งานได้แม้เปิดที่ f/2.5 และยิ่งหรี่รูรับแสงก็จะคมขึ้นอย่างต่อเนื่อง โดยมุมภาพคมชัดตั้งแต่ f/5.6

วิกเน็ตติ้ง

พบแสงตก (vignetting) ที่รูรับแสง f/2.5–f/4 แต่จะหายไปเมื่อปิดรูรับแสงเป็น f/5.6 โดยมุมภาพมีความคม

รีวิวจากผู้ใช้

ข้อดี

The bokeh, widely praised as 'magical' and among the smoothest reviewers have seen, with soft feathered falloff fore and aft of the subject
Sharpness that rivals modern optics while still looking natural rather than over-corrected
Compact, lightweight design for a fast telephoto, even with an adapter
All-metal, built-to-last construction with a satisfying full-stop clicked aperture ring
Historic pedigree as the lens behind the 'Afghan Girl' cover
The deliberate, thoughtful shooting experience of a manual-focus prime
Widely available at attractive prices

ข้อเสีย

Light falloff (vignetting) present from f/2.5 to f/4
Manual focus only, which some photographers coming from autofocus find limiting
No electronic communication when adapted, so EXIF lens data is not recorded

เทคนิคการใช้

Shoot it wide open at f/2.5 for subject separation and its signature smooth bokeh; the sharpness holds up well
Stop down to f/5.6 to eliminate light falloff and get sharp corners
Use a quality adapter (e.g. Metabones-grade) rather than cheap ~$20 units for reliable, tight-tolerance fit on mirrorless bodies
Since adapted EXIF won't record lens data, add it in post using a tool like the LensTagger Lightroom plugin
Deploy the built-in telescoping hood to guard against stray light
