Links are ephemeral. There’s no guarantee that any of the links below still works.

Information given on the sites listed is, in general, incomplete and inconsistent. If you can’t live with ambiguity and confusion, hide under your bed.

A number of lens types were made for many years, some with periodic major redesigns, others without. Either way, coverage claims change over time. “Fast” tessar types’ coverage has grown with redesigns. Dagor types’ coverage has shrunk with reconsideration of what coverage means. Be skeptical of all catalogs’ coverage claims.
