Kiron 105mm f/2.8 MC Macro Manual Focus Breech Lock Lens for Canon FD-Mount Review

The Kiron 105mm f/2.8 MC Macro is a manual focus macro lens designed for Canon FD-mount cameras, a mount discontinued in the late 1980s. Originally a third-party offering from the now-defunct Kiron brand, this lens features breech-lock mounting and multi-coated optics. At $129 in excellent used condition, it represents a legacy manual glass option for those shooting vintage Canon bodies or adapting to modern mirrorless systems.

As a 105mm macro with a fast f/2.8 aperture, this lens offers a classic focal length for tabletop and portraiture work. However, its FD mount limits compatibility to older Canon film SLRs or requires adapters for modern mirrorless cameras, which may introduce focusing constraints. The breech-lock design was specific to early FD lenses and differs from the later FD mount standard, so buyers should verify mount compatibility with their camera body. Manual focus and aperture control are the norm for lenses of this era, making it best suited for deliberate, slower-paced shooting.
