I think Amazon may have sold me a "gray market" lens. I have contacted them and Panasonic, and awaiting their replies. The lens came in a plain white box with no logo, just a computer-printed barcode label. The instruction manual, lens bag, and warranty card were missing. (the warranty card is the big flag, IMHO) The lens was protected by kind of a Tyvek slightly-padded bag that was rolling around loose in the box. The lens hood was in a plastic bag. Both seem to be fine. I'm not going to get too upset about it for a $135 lens like I would the camera or a $900 lens.
I'm having fun trying to figure out the camera features. I took a handheld picture in dim light at (I think) 1/5 second shutter speed and ASA 1000 (or do we call it ISO now?) and it looked sharp on the little display on the back of the camera. I haven't tried blowing it up and looking at the pixels.
