As you all know Pentax had a press conference in Dubai for invited people only. Among the invited was also a moderator of Slovenian photo site. He posted a photo essay about the desert near Dubai where they were given cameras to play with. Since this was Pentax event I bet they were using Pentax cameras and I believe some images were made with K20D. The author wouldn't tell which and he also removed exif due to NDA.
So here's a picture linked to the photo essay:
P.S.
only images named IMGP####.jpg (most of them) are made with Pentax cameras
