Based on comments from Roger Cicala (owner emeritus of LensRentals), repairing a lens doesn’t take too long regardless of the degree of damage. What takes time is waiting in the queue of other lenses awaiting repair, and perhaps waiting for parts if what’s needed isn’t available. So if the repair center isn’t busy, a quick turnaround time makes sense.
Thank for the info, clears things up a bit.
