I've seen this as well...I was in Seattle bracketing a skyline image and one of the images came out as you can see below. All other images on the SD card were fine. It was slightly cold/windy, but we're talking about 60F and windy, not -20F below.
I've never had any other corrupt images from this SD card so far in nearly a year of usage...
Wow, that is totally bizarre! It is almost as if the green channel totally checked out.

Ummm...the original posting indicated that the camera is new. What does Pentax support or the dealer have to say about this issue. It could be that a replacement camera may be in order.

I tend to believe that situations like this are definitely a circuit board problem. There are 2 ADC's, one handles the R,B channel, the other the G channel. I've seen complete green photos and the "magenta' ones. I can only assume a bad trace/or ADC that drops out and all of that channel are lost. They always say that electronics are likely to fail in the first few weeks. After that your safe. I wouldn't hesitiate sending the camera in for exchange/repair and including a print of the bad photos.
Then if it is intermittent (and techs do have a hard time w/ these types of problems) at least they have evidence.

It is a SMC Pentax DA lens....

What does that mean? Sealed or not sealed?
Yarn, the DA series lenses aren't weather sealed. The DA* (or "star") series lenses are weather sealed and also feature the Supersonic Drive Motor (SDM) in the lens for rapid, quiet autofocus.

To see if its a card problem.. try shooting with no card in, and watch the preview image.. Or, use the LCD DOF-preview and see if the pictures look normal then..
