Here are the two videos demonstrating the lossless slide zoom of 808 PureView while capturing video at 720p and 360p resolutions. 808 PureView supports up to 6X slide zoom for 720p capture and upto 12X zoom for 360p video capture. It is actually amazing to see the zoom levels that 808 PureView can attain.
