The Nikon 28mm f/3.5 traces its lineage directly to the very first 28mm SLR lens Nikon produced: the Nikkor-H Auto 2.8cm f/3.5, developed by Zenji Wakimoto and launched in 1959 alongside the pioneering, pro-level Nikon F. At the time the camera market was dominated by rangefinders, which lack a reflex mirror and therefore allow the rear element to sit close to the film plane. The Nikon F's SLR mirror box, combined with the F-mount's 46mm flange distance, made wide-angle design far more challenging. Wakimoto adapted the retrofocus principle pioneered by Angenieux of France to overcome this, and the Nikkor-H 2.8cm f/3.5 was born. As sources note, retrofocus lenses not only clear the flange distance but also reduce vignetting because the optics sit farther from the focal plane. The design saw several revisions: the multicoated 'K' (New-Nikkor) version arrived in February 1975 with updated cosmetics but the same six-element optic and, per one review, a seven-bladed diaphragm stopping to f/22 (an upgrade over the earlier five-blade unit). In 1977 the AI version introduced revised optics with a smaller front element, larger rear element, and thicker glass throughout to improve peripheral brightness. The AI-S version (1977-1981/manufactured, sold roughly 1981-1989 per one source) carried the same improved optics. Notably, the AI-S review states this f/3.5 does NOT feature the close-range correction (CRC) system found in its faster cousins the 28mm f/2.8 and f/2.0 AI-S lenses — though the Analog.Cafe review describes the design's floating-element CRC heritage, so sources disagree on this point (unknown/conflicting). The lens has a modest but devoted following among film shooters: one photographer calls the Nikkor-H 28mm f/3.5 his 'all-time favourite' lens that 'seems perfect,' with 'nothing else I need in terms of picture quality, build and handling.' No established nickname exists for this lens in the reviews.
สรุป: The Nikon 28mm f/3.5 is a compact, sharp, all-metal wide-angle that punches above its modest maximum aperture. It is best suited to documentary and street shooters who value a reliable, honest 28mm rendering, and to infrared photographers who will appreciate its clean, hot-spot-free performance. Its flaws — moderate color fringing, mild barrel distortion, some coma, and merely 'fair' bokeh — are typical of its era and largely correctable. Choose the multicoated K, AI, or AI-S versions for improved contrast and peripheral brightness; the AI-S offers the sharpest optics of the family. Not a bokeh showpiece, but a dependable, beloved workhorse for those who love the 28mm focal length.
ได้รับการจัดอันดับว่า "พอใช้" — ชัดเจนว่าไม่เป็นโบเก้แบบหมุนวน; เมื่อโฟกัสใกล้ที่รูรับแสงกว้างสุดจะได้บอลโบเก้ขนาดใหญ่ที่ไม่หมุนวน และมีโคมาเล็กน้อย
เป็นเลนส์ที่ค่อนข้างคม: รุ่น AI‑S ให้ความคมที่สุดโดยรวม ขณะที่รุ่นก่อน AI มีจุดที่ให้ความคมสูงสุดที่ f/8
เหมาะอย่างยิ่งสำหรับการถ่ายภาพอินฟราเรด — ไม่พบจุดร้อน (hot spot) และให้คอนทราสต์ดี ส่วนพฤติกรรมการเกิดแฟลร์กับแสงที่มองเห็นยังไม่ทราบข้อมูล
ให้คอนทราสต์ดี โดยเฉพาะในรุ่น K/AI ที่มีการเคลือบหลายชั้น ขณะที่ Nikkor‑H รุ่นเก่าที่เคลือบชั้นเดียวจะมีคอนทราสต์ต่ำกว่า
การออกแบบเรโทรโฟกัสช่วยลด vignetting และการปรับปรุงเป็นรุ่น AI/AI‑S ทำให้ความสว่างบริเวณขอบภาพดีขึ้น โดยแทบไม่มีข้อร้องเรียนที่สำคัญ
