For decades, Canon’s white EF L telephotos were the lenses you saw lined up at every stadium and every bird reserve. Canon has since moved to its mirrorless RF mount, and many of those EF lenses are now on the used market. They don’t stop working. On a modern RF camera with Canon’s adapter, most of them focus as well as they ever did, often better.

That makes adapted EF glass one of the best-value routes to serious telephoto reach on Canon mirrorless.
