Its obligatory these days for new cameras to include HD video, and the K-5 is no exception. Its full 1080 HD too. However its not great. After using Panasonic GH1's and the GH2 and Canon 5D MK II, 7D and 550D its a bit of a disappointment. There's very little control over the output and the footage is somewhat soft. Reminds me a lot of the video from Olympus m4/3 cameras. Like Olympus, Pentax have little experience with video, and it shows. It seems almost tacked on as an afterthought. These days I would have expected more.
