Originally posted by solitudebound There was a camera i followed a while back. It looked like a colored piece of square plastic tubing but it took one image but with two or three focus ranges. Just in front, the subject, and just in back. It's similar to focus tacking but in a single shot. The results looked almost holographic. I think the camera has since evolved into a more dslr like form but not much more info than that.
You probably mean Lytro, but that's a light field camera, so I think its a bit different.
Pentax cameras already have shift option, which can be helpful. It might mean you don't need to buy a rather expensive shift lens. If they add tilt, it can do some interesting stuff, because shifting lens and sensor can actually change the image in big ways. Most famous thing right now is making real life landscapes look like miniatures using tilt. But it has other uses, especially concerning DoF in macro range, using it for architecture photography and others
