I am very interested in mobile photography recently. I have heard that we can use the external lens of mobile phone to shoot better. So my friend recommended a mobile phone lens for me: Apexel lens:Apexel: The Best Mobile Camera Lens Its price is acceptable to me. But I don't know if it is so good as my friend said. I don't have any ideas about it. Maybe you have other better recommendations? I hope to get a mobile phone lens with a low price. I hope I can get your answer.
