I discovered that my iPhone 8 can shoot video in 4K at 60fps and would like to start filming with it. I really like the way the video comes out with HDR setting applied under the camera settings. The only thing is I need a telephoto lens to attach to it so I can zoom in farther with it than I can right now. I was researching today different lenses that you can attach to your phone and I came across the company Apexel which makes several models. I don't know whether I should get the 36x one ($40) or get the 60x one ($100). I plan on using it to film wildlife and zoo animals that average a distance of about 250 feet away from my iPhone 8. Has anyone used one of these before? If so, please share your experience below. Thanks for your help.
