If you own either a Samsung Galaxy S7 or S7 Edge for 150 euros or £120 you can now buy a protective case from Samsung that allows 2 different lenses to be screwed on in an instant.
These are no ordinary lenses. They are made of stainless steel. One is a 110º wide angle lens and the other a telephoto lens. Samsung claim the quality of these optics are top notch and that the end results will be distortion free.
Of course if you want a wide angle lens, just buy a LG G5 which has a 135º lens as standard. Still you do get a telephoto lens with this as well, so this could be just what the doctor ordered!
