I picked up a couple of AY-DVM83PQ tapes and heard that this might be bad for a SONY camcoder because Panasonic uses a wet tape system compared to a dry one from SONY.(or vice versa)
They also say 83ME...Metal Evaporated I guess. Which is better, Particle or Evaporated
Some tapes use a dry lubricant, some use a wet lubricant. Do not mix the two tape types. If you do switch, make sure you clean the heads before using the other tape. The best advice is to pick one and stick with it.
I'm relatively sure that the Panasonic is dry and the Sony (at least the "premium"s) are wet. Regardless though, what Jay said about picking one (I've heard it's not a good idea to even switch brands much less if they're wet or dry) is absolutely true.

I think Panasonic tape is dry. Seems I read here once that it was the opposite of Sony, and they are wet. It either case, it won't hurt to clean the heads before using them.
I have used Panasonic's from the beginning and stick to just one. All of the above comments are true. You are asking for trouble if you bounce back and forth between vendors.
PQ are wet and MQ are dry as told to me by a Panasonic Rep a few years ago on the 2-pop website. Also confirmed by Tape Resources. I use PQ on my VX2000 as I have found that the MQ sometimes causes tearing in the image. Color fidelity is about equal. PQ is all I use now. Very happy with them. They are also compatible with the over the counter Panasonic consumer tapes (Walmart, etc). Eliminates head cleaning between changes.
Really the PQ is wet? I had seen a discussion of this on the DVX users forum and they said Panny has made the PQ dry now, hmmm. I been using the MQ tapes in my DVX100a, no problems, yet.
I was told by Panasonic that now both the MQ and PQ are dry. Tape Resources is my source for all my tape and DVD stock and they also advised this. It used to be that the PQ was wet and the MQ was dry but not any more, or so I'm told.
I've used Panasonic tapes in my VX2000 for 3 years with no problem. tried Sony tapes on 2 different occasions and got all sorts of funny stripes and loss of synchronisation. After cleaning the heads it was OK again, but I decided mixing brands was not a good idea.
