Sony announces Xperia Z1, with 5 inch 1080p screen and 20.7 megapixels

Recently, many corporations announce their new products. Apple, Samsung and Sony unveil their smartphones one after another.

Sony announces its new smartphone and camera lenses.

Like the Xperia Z, the Z1 is completely waterproof. You can submerge it in water to a depth of 1.5 metres for up to 30 minutes. If you've destroyed a phone by dropping it in the toilet -- or by making calls in the rain -- the Z1 might be the phone for you. It keeps water out by sealing its ports with smaller flaps. While the Xperia Z placed a flap over the headphone jack, the Z1 has simply made the jack itself waterproof, meaning you don't need to undo it every time you want to plug your headphones in.

Probably the most exciting update to the Z1 is the camera, which now boasts a whopping 20.7 megapixels. That's a significant jump from the 13 megapixels of its predecessor, but Sony says that there's more than just a megapixel bump going on.

The sensor size, at 1/2.3-inch, is bigger than what you'd find on your normal smartphone and is similar to the Samsung Galaxy S4 Zoom's (1/2.33-inch). In comparison, the iPhone 5 uses a small 1/3.2-inch sensor, and the HTC One's UltraPixel sensor is slightly larger at 1/3-inch. The Nokia Lumia 1020 has the biggest sensor at 1/1.5-inch for smartphones running a modern OS.
