Canon 100-200mm f/5.6 SC Manual Focus Breech Lock Lens for FD-Mount Review

The Canon 100-200mm f/5.6 SC is a manual focus telephoto zoom designed for the breech-lock FD mount, making it compatible with older Canon film bodies and some adapted digital setups. As a legacy lens from Canon's pre-EOS era, it offers a useful focal range for portraits, wildlife, and distant subjects at a budget-friendly price point. The f/5.6 maximum aperture is modest but typical for zoom lenses of its generation, and the SC (Spectra Coating) designation indicates Canon's standard single-layer coating for improved contrast and flare resistance.

This lens is sold in bargain condition with caps included, meaning it will show visible wear and may have optical imperfections that could affect image quality. It's best suited for experimenters, film photographers, or those looking to explore vintage glass on a tight budget. Without reviews or detailed condition reports, expect cosmetic and functional quirks common to used legacy optics. It's a low-risk entry point into the FD system, but not a lens for those seeking modern optical performance or build quality.
