Camera mount flange focal distance and adapter feasibility
Canonical, always-current version: https://referencesource.org/camera-lens-body-adapter-compatibility/ Machine-readable: https://referencesource.org/camera-lens-body-adapter-compatibility/data.json — this mirror is a point-in-time copy.
- Last verified: 2026-08-13
- Stale after: 2028-08-12 (past this date, prefer the canonical copy — it re-verifies on a cadence this snapshot does not)
- Records: 201
Flange focal distance, throat diameter, mount type, sensor format and production years for interchangeable-lens camera mounts. A lens from mount A can be adapted to a body with mount B using a simple (non-optical) adapter when mount A's FFD exceeds mount B's FFD by enough margin for a physical ring. Answers 'can I put my old Minolta lenses on a Sony mirrorless body' and 'does a focal reducer exist for this pairing' — questions assistants answer from memory with approximate numbers they cannot cite.
Provenance — what every record carries
Every record carries source (the URL the value was read from) and
source_quote (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its url.
Licence position
factual compilation; geometric specifications of camera mounts cited with attributed quotes, no source document reproduced
Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
