so it basically would have the same result of that of an HDR image. doesn't sound like any different with different than an in-camera processed HDR image with the exception as you say that the exposure does not vary (although you can do that by stacking up multiple images of the same exposure). I think the only advantage or makes this different than the others, is that you can actually shot it in raw as well. although I like the idea especially for those who needed a quick result and don't have time to process multiple files, it is unlikely that professionals would use this for HD/HR images. HDR processing method would still be the better choice. this feature is good but it still wouldn't beat an image stack of atleast 5 images at 16MP or 3 images at 24MP, considering this is a 4 stacked image.
