The Rokinon 28mm f/2.8 is a wide-angle prime from the manual-focus era of the 1970s and 1980s, sold under the Rokinon badge in various mounts including Pentax K and Canon FD (some copies were also branded 'Automatic Wide MC'). Its true origins are murky: as one Reddit commenter notes, 'you won't find a comprehensive review of this lens because Rokinon 28mm f/2.8 lenses were likely made by different manufacturers at different times.' Community speculation on Pentax Forums points to a Japanese origin (one owner noting it was 'made in Japan, so it's not just a samyang rebrand,' guessing at Tomioka/Ricoh), while another forum thread claims 'it's one and the same with Vivitar, just different packaging and lettering.' Because Rokinon was fundamentally a rebadging house, no single definitive manufacturer, optical formula, or lineage can be confirmed. There are no established nicknames or cult jargon for this lens. Rather than a cult favorite, the reviews paint it as a modest, workmanlike wide-angle: owners describe being 'not horribly impressed' and 'disappointed' with results, though these impressions were tempered by 'lackluster films and bodies,' cheap film, and self-developing/scanning. It is a lens bought for utility and affordability rather than reputation.
สรุป: The Rokinon 28mm f/2.8 is a modest, budget vintage wide-angle whose true maker varies from copy to copy. It rewards stopping down with a sharp center but shows edge softness and vignetting wide open. It's best suited to hobbyists and film shooters who want an inexpensive, characterful 28mm and aren't chasing a legendary reputation — this is a workhorse rebrand, not a cult classic.
ขอบภาพค่อนข้างนุ่มเมื่อเปิดรูรับแสงกว้างสุด แต่เมื่อหยุดรูรับแสงลงจะให้ความคมชัดสูงมากบริเวณกึ่งกลางภาพ
พบการมืดมุม (vignetting) ที่สังเกตได้เมื่อใช้รูรับแสงกว้าง
