FWIW - a better experience to report. I ordered a 31mm limited from the pentax webstore on Nov 28, around midnight. On December 2, I received an email that the lens had shipped. That same day my Paypal account was charged.
The tracking number in the email was useless; it kept telling me that UPS had not received the package.
So, I called the webstore today. They assured me the lens had shipped, and when they logged into the UPS site, were able to tell me the lens would be delivered to my home (in upstate NY) today.
A few hours later, the lens arrived.
Why, oh why, do I think I'll be taking lots of pictures with it this weekend?
