What are the technical advantages of the L-Mount system?

L-Mount has an effective diameter of 51.6mm that can take in sufficient light for not only an APS-C but also a full-frame sensor. Combined with the remarkable durability thanks to the four-tab bayonet structure which is strong enough to support even heavy telephoto zoom lenses and a short flange distance of 20mm, this mount system is future-proof with a superior communication advantage that is flexible and full of potential.
