The 90mm lens has a built-in Series VI thread, and I have confirmed this with a retaining ring.
However, it's also supposed to be removable, leaving behind a more standard 49mm thread.
Anyone can confirm this from experience? If so, what is the safest way to remove the Series VI thread without marring the lens?
