Kenko

Kenko is a Japanese brand and company known for manufacturing photographic accessories. The firm focuses on optical products designed to enhance camera performance, including filters, teleconverters, extension tubes, close-up lenses, and other accessories used in both digital and film photography. Kenko products are marketed worldwide and available through camera retailers, online stores, and distributors.

The product lineup emphasizes practical, budget-conscious options alongside higher-end offerings. The filter range includes multi-coated circular polarizers, neutral density, ultraviolet, and specialty filters, commonly sold under the PRO1D or MC lines. Teleconverters and extenders, sold under the Teleplus brand, increase focal length for extended reach, while close-up lenses and macro accessories enable higher magnification for close-work photography. The company also supplies lens hoods, adapters, mounting rings, and related accessories to support compatibility across camera systems.

Kenko places an emphasis on compatibility with major camera brands and on optical coatings that help reduce reflections and flare. The brand maintains a presence in both consumer and professional markets and positions itself as a source of affordable, wide-ranging camera accessories in competition with other optical manufacturers.

In Japanese, the word kenko (健康) means health, a term unrelated to the company but sometimes noted in discussions about the brand name’s meaning or transliteration.
