I don't see the added value for NASA to bring back cameras bodies and lenses. It is dead weight and weight is the ennemy in space (need energy to accelerate it). But I might be wrong...
Some did come back. They did take pictures of the command module and LEM after jettison prior to re-entry for engineering purposes, so thay had to have at least one camera available in the CM. I suspect they had more than one for redundancy.
Anything that actually went to the moon got left there so far as I know. I don't even recall seeing a picture taken from the LEM of the CM during lunar orbit rendevous, but I've seem plenty of the LEM ascent stage taken from the CM. Seeing a picture of the CM taken from the LEM at lunar orbit rendevous would prove at least one came back from the lunar surface.
At this point I'm not sure even NASA could give a reliable answer. Everything is on paper somewhere in a giant warehouse if it wasn't already shredded.
