I don&#x27;t think the point is to let you switch between different versions of an image (though the after-the-fact adjustments of depth of field are really slick). I think it&#x27;s more that with a bunch of sensors and lenses you can simulate a much larger sensor and lens, so you get the low noise and choice of lens profiles of a DSLR without having to actually lug one around, or a bag of lenses to go with it. Some of those pictures in their gallery are pretty awesome, particularly in terms of noise. I&#x27;d never have guessed that they were taken with something so portable.
