A testament to the popularity of the iPhone (ok, and maybe the iPad, too), Apple has surpassed Nikon as the second most popular camera brand on Flickr. Why is this significant? Well Apple doesn't make standalone cameras (QuickTake and iSight are both discontinued) but its iPhone cameras are prolific and popular. Leading the pack is Canon with 13.4 per cent, Apple folloes with 9.6 per cent and Nikon has 9.3 per cent.
