The lucky Japanese are getting a mini version of the flagship Sony Xperia Z1, dubbed Z1 f, for the local carrier NTT DoCoMo. Another leaked promotional brochure shows the handset in black, white, lime and pink colors.
The specs that were shown before include the same awesome 20 MP camera with Sony G Lens that is planted in the Z1, but in a much lighter and more compact body, bearing a 4.3" display with 720x1280 pixels of resolution, and a smaller, 2300 mAh battery. The rest stays the same, though, with 2.2 GHz Snapdragon 800, 2 GB of RAM and 16 GB of internal memory.
The Sony Xperia Z1 f will also keep its IP58 waterproof certification, meaning you can dip it in quite a bit of water for a long time before anything happens to the munchkin.
