"Look at the prosumer camera market, both DSLR and new mirror-less models. A significant population of people desire interchangeable lens. A phone with interchangeable camera module could have all kinds of possibilities." If you told me I could have a large, high-quality sensor (wouldn't even need full-frame necessarily), and a single fast lens that covered a wide range of focal lengths with excellent sharpness, chromatic aberration, bokeh, etc, I and many other passionate photographers would buy it in a heartbeat. Unfortunately, the reality is that prime lenses, due to fewer components and lens elements, tend to have better specs than zoom lenses. The super-zooms you see on the market with insane focal ranges (like 18-250) are typically very slow (f/4.5 or so), very heavy, and if you look at comparisons their quality is crap. So I think I would rewrite your comment to read "a significant population of people desire high-performance capabilities, and currently the only way to get on the higher-end of that spectrum is via interchangeable lenses." Interchangeable lens attachments for phones have been attempted and have not done too well because ultimately they just don't perform as well[1]. Also, if you are bothering to carry around a separate lens attachment for a mobile device, you are probably in a situation where you could carry a mirrorless camera as well. I know if I had the choice between carrying some lenses and a slightly heavier Sony A7 vs. lenses and a phone, it would be the A7 all the way. http://www.dpreview.com/previews/sony-cybershot-dsc-qx100 http://www.dpreview.com/previews/sony-cybershot-dsc-qx100
