Thread sizes verified 2026-08-28 against community-maintained per-mount lens specification tables (compiled from the manufacturers' own spec sheets), matched brand-strictly to our lens index. Lenses whose thread we could not uniquely verify are left out rather than guessed — coverage grows as verified data lands.
