The Sony QX series of lens-style cameras have caught the imagination of many and one of the great things about them is the flexibility to be used with pretty much any smartphone (Android or iOS). However, one of the benefits of owning the Xperia Z or Xperia Z1 is that Sony has developed a custom case, easily allowing you to mount the QX10 or QX100.
The Sony SPA-ACX1 camera attachment is designed for the Xperia Z, whilst the Sony SPA-ACX2 is for the Xperia Z1. Sony says the cases can be used on a day-to-day basis and when the camera is not in use, the case can be closed so as to not expose the attachment area. Both cases weigh around the 20g (0.7 oz) mark. In the UK the cases will cost £25.00, in Europe it will cost €29.00 and in the US it will cost $29.99. They come in black and white colours to match your phone (no purple option unfortunately) and should be available in the next few weeks.
