This Panatomic-X was obviously stored in VERY POOR conditions, probably a hot humid garage or something like that.
Don't be nervous your stuff is fine.
On a side note, don't buy the Panatomic-X 70mm that's on eBay, since that's the stuff, he has a lot of it for something like $29.99+ shipping. I've emailed him about the issue but he hasn't responded nor pulled the posting :/ I feel bad for people who buy it.
