WHAT CONDITION THE CONDITION IS IN: 88-Day Confirmed Operation Warranty. Cosmetically very clean. Optics show minor dust typical for a lens of this age. Focus is smooth, just slightly stiff but not an issue. The aperture ring works as it should. Includes a Canon FD 50 extension tube and original lens caps.

The FD 100mm isn’t going to win a popularity contest. It’s a macro lens with all the charm of a polite accountant. Modest, reliable, and suspiciously good at its job. It’ll turn a leaf into a landscape or a fly’s compound eyes into a tiny universe, provided you remember to attach the optional FD 50-U extension tube and, more importantly, pay attention. But it also makes a swell portrait and landscape lens.

The f/4 to f/22 aperture range gives you control over what’s sharp and what melts into polite obscurity, like your in-laws at dinner. Optically, it’s a modified Tessar, five elements in three groups, engineered to avoid distortion and chromatic chaos. It boasts a flat field, which means it won’t lie to you.

The focus throw is long and deliberate. It’s inconvenient if you’re used to autofocus, but satisfying if you enjoy feeling like a competent adult for five seconds. In short, it’s a nagging, precise, slightly intimidating companion that reminds you that even a fly deserves a proper look, and so do you, whether you like it or not.
