Before trying the product, I thought I was going to expand some objects a bit, but when I tried it, I was amazed at how much it expanded. It is difficult to compare the normal vision of the photos that are made with mobiles, normally the photos that are made with the mobiles looks all smaller, but with this objective I am able to enlarge very far objects, which I am not able to see Simple view and see them from the screen of my phone. The telephoto lens looks robust and of good quality. In addition to being able to be used with the telephone adapter, this telephoto lens can be used directly with the adapter it comes with. If you are a fan of photography, astronomy or just want to take pictures of your neighbors, this telephoto lens is for you. It is really small but the results that can be achieved are amazing. While this telephoto lens enlarges x8, if you add the phone's zoom, you can really zoom in a lot. I recommend your purchase.
