Quick answer
Choose the Canon FD 50mm f1.4 for the safest fit on most Canon FD-mount film SLRs and a clean, tested example. Choose the Canon FL 55mm f1.2 only if you need the extra half-stop and your camera explicitly accepts FL lenses.
Mount compatibility is the first decision
The FD 50mm f1.4 is an FD-mount lens, so it is the natural choice for cameras built around the FD system. The FL 55mm f1.2 uses the older FL mount; it is intended for 35mm SLR systems that accept Canon FL or FD-series lenses, but not every FD body is guaranteed to work with FL glass. Check your camera manual or test the lens before committing.
If you own more than one Canon film body, the FD lens is the more flexible option for a mixed kit. The FL lens is better treated as a specialist purchase for a body you already know accepts it.
Aperture versus tested condition
The FL 55mm f1.2 gives you a faster maximum aperture, which can help in low light or when you want the shallowest depth of field. The trade-off is that the listing does not state the same detailed condition notes as the FD lens, so you are buying more on specification and less on a documented inspection.
The FD 50mm f1.4 is listed in excellent condition, tested and fully functional, with clean glass free from scratches, haze, and fungus, smooth focus, and no oil on the aperture blades. For a used fast prime, those details matter more than a half-stop of speed if you want predictable results from day one.
What the included accessories tell you
The FD lens includes front and rear caps and the original lens hood. That saves you from sourcing a hood separately and suggests the lens has been kept with its original kit. The FL listing does not mention included accessories, so budget for caps or a hood if you need them.
Trade-offs at a glance
- Mount fit: The FD 50mm f1.4 fits FD-mount cameras directly; the FL 55mm f1.2 requires a body that accepts FL or FD-series lenses. Check your camera's compatibility before choosing the FL lens. If you are unsure about FL compatibility, the FD lens is the safer buy.
- Maximum aperture: The FL 55mm f1.2 is faster than the FD 50mm f1.4, which helps in low light and for very shallow depth of field. The FD lens is still fast enough for most film work and easier to focus accurately wide open. Choose the FL only if you regularly shoot at f1.2 and accept the compatibility risk.
- Condition and accessories: The FD lens is documented as tested, with clean glass, smooth focus, and no oil on the aperture blades, and it includes caps and the original hood. The FL listing does not provide the same level of condition detail or accessory list. For a used lens, documented condition is often worth more than a small aperture gain.
