DxO One Android camera add-on promises "pro-level" photos for $499
The DxO One is equipped with a 1" 20MP sensor and has a fixed f/1.8 aperture, which guarantees a better performance than pretty much any smartphone camera out there, both during the day and in low-light as well. The add-on weighs in at around 108 g. and is pretty compact, although it's not something that you'd always keep plugged in your phone (unless you carry your phone in a bag). DxO says the device can snap up to 200 photos in one charge, although no concrete information on the battery powering it has been officially released.
