We have earlier brought you comparisons between Lumia 1020 and iPhone 5 and produced crops to highlight the difference between the images captured with using Flash.
But, here are two images from same source who has uploaded earlier photos. You don’t need to even crop the images for highlighting the difference. There is visually massive difference between the image quality. Both the images were captured in low-light without using flash and see the power of OIS and oversampling!!
Thanks Nano for the Tip. Cheers!!
