How does the iPhone 5s camera compare to the 925?

There's been a lot of comparisons done lately between the iPhone 5s and the Lumia 1020 cameras. How about comparing the 5s with the Lumia 925 for camera? Are there any articles on that? After all, even the 925 was considered to be one of the best cameras on the market till 1020 came along. So has anyone compared the camera images from the two?
