I'm new to Nikonians, so forgive if this has been covered.
It seems really difficult to determine the compatibility of the various Nikon "PK" tubes with Nikon lenses. I'm concerned that using, for example, a PK-12 alone with a 50mm 1.4D will cause damage. Should one always use the PK-11A first? And, if "yes" I assume that the PK-11A should be mounted closest to the camera body?
If someone can guide me to the "official Nikon word" posting, I would appreciate it.
