The open lens-compatibility dataset
Every "does this fit" answer on FitMyLens comes from this dataset — 596 lenses across 6 mounts, 82 camera bodies, 9 adapter families and 16 teleconverters (80 compatibility rows), plus filter-thread sizes. Every record cites the manufacturer page it was read from — nothing here is inferred or fabricated.
