Thread sizes verified 2026-09-03 against per-mount lens specification tables and, where no such table exists (L-mount), the manufacturers’ own published specification pages, 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.
