Overview
The Canon FL 55mm f/1.2 was introduced in July 1968 as the flagship standard lens for Canon's FL-mount SLR system. It sits in the middle of Canon's fast-fifty dynasty: the R 58mm f/1.2 of 1962 begat the FL 58mm f/1.2 of 1964, which was refined into this shorter, recomputed FL 55mm f/1.2 in 1968; the line then continued into the FD 55mm f/1.2 (1971), the FD 55mm f/1.2 S.S.C. (1973), and the legendary FD 55mm f/1.2 S.S.C. Aspherical (1975) — the first 35mm SLR lens to use an aspherical element. This lens was calculated before computers did the ray tracing, its seven elements in five groups worked out with slide rules, and it was built entirely of metal and glass. Canon's engineers were chasing the same goal every fast-lens designer faces — taming field curvature and flare at maximum aperture — and by the reviewers' own account they 'did not completely succeed,' which is precisely why the lens is prized today: its imperfections ARE its character. No established nickname is evidenced for this specific lens (unlike generic 'nifty fifty' fifties or the 'legendary' Aspherical that followed it). Its cult following rests on being the sweet spot of the lineage — refined enough to be genuinely usable, old enough to keep the painterly optical signature — while remaining affordable, roughly $150-$300 for a clean copy.
Verdict: The Canon FL 55mm f/1.2 is a character lens, full stop — for the photographer who wants painterly, dimensional f/1.2 rendering with glowing highlights, dissolving bokeh, and layered depth, not clinical sharpness. It rewards shooting wide open and composing in planes of distance, and its single-coated glow and per-element color separation give a look modern computed lenses simply don't. If you chase resolution charts, look elsewhere; if you want an affordable, usable slice of Canon's fast-fifty heritage whose imperfections are the whole point, this is the sweet spot of the lineage.
Optical Character
Bokeh
Smooth and creamy, with a pleasing out-of-focus rendering that adds depth and separation to the subject.
Color
Warm and natural tones, with a slightly muted look that gives images a vintage feel.
Flare resistance
Mild flare and ghosting when shooting into bright light, adding a subtle character to the image.
Contrast
Moderate contrast, with a softness that can be pleasing for portraiture and landscape photography.
Vignetting
Noticeable but not excessive vignetting, which can be used creatively to draw the viewer's attention to the center of the frame.
Community Insights
What people love
- The wide-open glow that wraps around bright subjects and bleeds into surrounding tones — a signature no computational/modern lens replicates.
- Bokeh that dissolves rather than blurs, with melting edges and colors bleeding together for a painterly, rather than photographic, look.
- The f/1.2 depth layering that separates a scene into foreground, mid-ground, and background planes, giving strong dimensional 'pull-through' rendering.
- Color separation and per-element luminosity — greens rendered at different intensities, saturated reds/magentas — where a modern lens would flatten everything uniform.
- The single-coating micro-glow around bright edges, likened to the vintage Canon K35 cinema-lens look.
- Its place as the usable, affordable sweet spot of Canon's f/1.2 lineage — roughly $150-$300 for a clean copy.
What people dislike
- It is not clinically sharp wide open — reviewers openly tell resolution-seekers to buy a modern fifty instead.
- Its engineers never fully tamed field curvature and flare at maximum aperture, so the single-coated glass shows lower contrast and veiling glow that not everyone wants.
- It is essentially a one-aperture lens for character: stopped down it behaves like an ordinary fifty, so the appeal lives almost entirely at f/1.2.
Pro Tips
- Shoot it wide open at or near f/1.2 — that is the entire reason to use this lens; its glow, dissolving bokeh, and depth layering appear only there.
- Compose in layers: place elements at clearly different distances so the f/1.2 falloff can build the foreground-glow, mid-ground-soften, background-pure-color separation the lens is known for.
- Backlight or side-light bright subjects to invite the highlight bloom and micro-glow the single coating produces — lean into it rather than fighting it.
- Focus with great care; depth of field at f/1.2 is razor-thin, so nail the eye/subject plane and consider magnified manual focus.
- If you want crisp, contrast-heavy results, stop the lens down — but accept that doing so trades away the character, so reserve stopping down for when sharpness genuinely matters.
