The Tokina SD 400mm f/5.6 for Canon FD is a vintage, manual-focus super-telephoto prime lens produced in the late 1980s and early 1990s. Featuring Tokina's proprietary Special Dispersion (SD) glass, this lens was built as a higher-end alternative to their standard consumer RMC line, offering significantly better control over chromatic aberration and improved contrast. Because it uses the native Canon FD manual-focus mount, it is highly sought after by vintage film photographers and modern mirrorless shooters looking for an affordable wildlife or sports lens.
