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.
