Unlike Lumia 1020, Zenfone Zoom comes with only 13 MP camera and without oversampling to provide that amazingly detailed PureView image quality. But its claim to glory is its 3X optical camera zoom in a 11.95 thin body. Now, this makes us quickly mention Samsung’s 2nd attempt to imaging crown, Samsung Galaxy K Zoom with a 10X optical zoom. Even with a 10X optical zoom it was still not able to match the Lumia 1020 in imaging quality.
So, while 3X optical zoom in a relatively thin body is fine, with a 20 MP camera, great imaging quality and 2X digital zoom in even thinner bodies Lumia 930 and Lumia 1520 still look like formidable challengers to Asus Zenfone.
