Canon EF
Q: My question is not on this page? A: Ask it in the URL, for example /ask/which-canon-ef-camera-should-i-buy. Any question written as words after /ask/ works.
The mount of Canon's DSLRs. EF lenses cover full frame; EF-S lenses are for the APS-C bodies only. A huge used market.
Every EF and EF-S lens adapts to Canon RF mirrorless bodies without losing anything.
