Never knew such a thing existed until I accidentally stumbled across it on some page or other this morning. Apparently you can take a photo and then later, during processing, decide what part of the photo you want in focus. (">

One of the google camera apps can sort of simulate this.
The actual cameras came out a few years ago and aside from reviews on tech blogs, I didn't see much else about them, It's clever tech, but I don't really see a use for it other than an expensive toy.
Panasonic's 4k camera's have 'Post focus mode' which looks really good.

Panasonic has combined its cameras' 30fps 4K shooting capability with its high-speed, high-precision DFD (Depth from Defocus) auto focus technology. A whole series of shots is taken in rapid succession, one for each of the system's 49 autofocus points.This means shots aren't exactly instantaneous, but assuming the camera runs at its full 30fps it sounds like it should be possible to capture a post focus shot in 1-2 seconds.
There's no real need for a tripod, since there's no focus stacking or image merging technology going on here. Indeed, Panasonic's own Post Focus video (above) shows a photographer using a camera handheld.
As Panasonic explains, you can use this Post Focus mode to experiment with different focus points and background blur, find the perfect focus point for macro shots or just make completely sure that you don't lose the shot of a lifetime to a focus error.
The new canon 5Dmk4 has a focus select in post as well, the light field cameras were expensive and strange looking things in the past so never really caught on, I like to know what is going to be in focus by setting it manually in the camera as I take the photo, I would never really trust something like this to get it right same reason I don't like some of the automatic focusing options on the dslr
