Canon FD 85mm f/1.2 S.S.C. Aspherical

Nikon shooters cross-shopping the 85mm slot in the late seventies got the Nikkor 85mm f/2, a sober, sharp, sensible portrait lens. Canon shooters got this thing, a stop-and-a-half faster monster with a ground aspherical element and a front group heavy enough that the whole lens noses down in your hand. That gap, f/2 versus f/1.2, is the entire story. Nikon built a tool. Canon built a statement about what was optically possible, and charged accordingly.

Wide open at f/1.2 the rendering is unmistakable. Center sharpness is genuinely usable, which is the whole point of grinding an aspherical surface into a fast lens (it tames the spherical aberration that otherwise turns f/1.2 into a soft glow). Contrast drops at maximum aperture and there is some veiling, so reds and blues sit a touch muted until you close down a stop. The out-of-focus rendering is the reason people still pay for it: backgrounds melt down to big soft discs, though the ground aspherical element leaves a faint onion-ring texture inside those highlights rather than a perfectly creamy wash. Specular highlights stay circular near the center and lemon toward the corners, the usual fast-lens cat's-eye. Stop to f/2.8 and it sharpens up across the frame and the contrast snaps into place.

This is a portrait lens first and an available-darkness lens second. Head-and-shoulders work at f/1.2 gives you a sliver of sharp eye against a wash of nothing, the look prized by available-light portrait and editorial shooters working in dim interiors. Documentary people reached for it for the same reason: it sees in the dark. Manual focus only, FD mount, so it lives on an A-1 or an F-1, and focusing wide open is unforgiving because the depth of field is paper thin and the focus throw is long. You earn your keepers.

The honest weakness is weight and front size, plus the price of admission. The 72mm filter thread tells you how much glass is up front, and the lens balances badly on a small body. Longitudinal chromatic aberration shows up at f/1.2 as green-magenta fringing on out-of-focus highlight edges, the classic fast-glass tell. And the early S.S.C. Aspherical, with its hand-polished aspherical element and nine blades, commands a real premium over the optically similar but cheaper-to-build FDn 85mm f/1.2L that replaced it in 1980. Collectors chase this specific version, which has pushed used prices well past what the optics alone justify.

For metering, the f/1.2 is the argument. When you are working a candlelit interior at the bottom of your shutter range, meter the scene wide open in Zone Light Meter and let the app place the shadows where you want them; that extra stop and a half over a normal portrait lens is often the difference between a handheld frame and a tripod you did not bring. Once you have a Canon FD body to mount it on, this is the fast 85 people remember, the one that set the look everything after it chased.
