Sony was the first one to bring a huge, 20.7 megapixel camera to the Android world, and, for a short period of time, it was arguably the king of Android cameraphones, back in the Xperia Z1 days. Fast forward to today, through the Xperia Z1 CompactXperia Z2Xperia Z3, and Xperia Z3 Compact (now with the Xperia Z4 in Japan), and the megapixel count stayed the same, though Sony has improved its sensor, lenses, as well as its camera software.

However, Xperia RAW image format is not available for Sony phones, despite the fact that the latest version of Android supports it. Asking about its availability on the Sony Support Forums, users were reassured that Sony will consider including this functionality should there be a demand for it. The way things are now, Sony has opted for no support for RAW capture inside its Lollipop firmware (there are two modes in addition, one that offers full RAW support, and an optional one). Needless to say that some users on the thread are arguing in favor of full support, so, if there are any more of you out there, let Sony know you want your Xperia RAW image format support.
