I was really surprised to discover that my iPhone's panoramic function works perfectly with the ōlloclip 2x telephoto lens! This image is right out of the phone, no additional tweaking. Hofburg Wien in the evening sun.
Ōlloclip fisheye lens with circular polarizing filter on iPhone 4S. Very unsharp, I'll need to test this combination again - I cannot believe that the filter reduces image quality on the fisheye that much! Maybe camera shake?
