Always on, doing what? Are you talking about the color LCD? It cannot be used as a viewfinder. This fact is not limited to Pentax, it's a limitation of Digital SLR's. The reason is that the CCD chip is not exposed until the viewfinder mirror flips up, out of the way. At this point, the optical viewfinder blacks out momentarily, and the CCD gets a chance to capture an exposure. This is how "through the lens" SLR's work.There are times when I'd like to have the LCD always on. But I can't see a method to accomplish this.
On digital point and shoot cameras, the optical viewfinder does not look "through the lens", thus there is no mirror, thus, the CCD can sit there exposed all the time, and the result is that it is possible for the color LCD to be used as a viewfinder.
