The Samsung Galaxy S4 Zoom features a 16 megapixel camera with 10x optical zoom for closeups on distant subjects. Meanwhile the Nokia 808 PureView has a 41 megapixel camera which gives you the power to crop with 4x towards the center of the image, which allows you to zoom into any part of your image.
Check out the following test video samples and find out how the pixel oversampling technology on the 808 PureView fairs against the true zoom on the Galaxy S4 Zoom
So what do you think is better? Nokia's PureView or a physical lens with optical zoom? Keep in mind that that the Nokia Lumia 1020 will improve the video capture of PureView even further.
