Sony Cyber-shot QX "smart lenses" are a truly unique approach to the shortcomings of phone cameras. Most obvious of these shortcomings is absence of optical zoom; ameliorated to a degree by increasing pixel count. With 8 & 12 megapixels now common in smartphone cameras, 2x digital zoom (or cropping after the fact to achieve the same outcome) yields an image in the 2-3 megapixel range which is quite acceptable for many purposes.
Previous approaches to lack of zoom has been add-on lenses, most commonly wide-angle or macro, although occasionally, moderate telephoto. To my knowledge, all of these have been fixed focus; no zoom. Most have been under $100; at such prices, optical quality is not available.
Another problem with phone cameras is small sensor size. Small size is a major design parameter of mobile (cell) phones. This has included such measures as replacing mini USB with Micro USB, & restricting battery size & so runtime. Camera sensor size has been another casualty. Why is this a problem? All other things being equal, small sensor size leads to poor low-light performance & noisy images.
Finally, any add on lens to date has been a single phone solution, due to the need to optically align the add on with the phone lens. Add on lenses also restrict, or eliminate the possibility of fitting a case to the camera: a deal breaker for some.
Sony's Cyber-shot QX10 & QX100 "smart lenses" are a real thinking outside the square solution to the problems listed above. Part of the creativity of the solution is hinted at by the quotes around "smart lenses", above. These are not just lenses, they are complete cameras: complete at least, apart from a viewfinder. Viewfinder capability is provided by the screen of the attached smartphone. Because they are cameras in their own right, optical alignment is not necessary. As a result, these lenses can be used with any Android or iOS phone they can be physically clamped to. This means almost any recent model smartphone or tablet, including Kindle. Actually, clamping to the body of the phone isn't necessary, as the interface is via WiFi. This brings up a further benefit of the "smart lens" format: remote shutter release (up to 10 metres) is inherent in the design.
Final part of the solution is the 2 "smart lens" models:
QX10: cheaper model, smaller sensor (18.2mp, 1/2.3"), 10x zoom — aimed at a less serious photographer who values low price & more zoom.

QX100: more expensive, aimed at a more serious photographer who understands the improved image quality afforded by a larger, 1 inch, 20 megapixel sensor & f1.8 aperture, 3.6x zoom, Carl Zeis lens. Also must be able to accept the substantially higher price.
