I'm using this with a Galaxy S24 Ultra, which has camera lenses that protrude from the back of the phone quite a bit. The clip frame for this microscope lens comes with optional pads you can use to accommodate for a phone like that. The clips will inevitably go over the buttons, but that's really not a big deal to me.Anyways, I included some test shots of various things. First is the texture of a plastic armrest, then closeup shot of outdoor fabric from the same chair. Last is a small ring that my partner was wearing. These photos were not processed or cropped in any way. Depending on your phone camera's lens, you'll likely end up with a little big of vignette unless you crop it or combine with your phone's zoom. You do need to get pretty close to the subject with this and focusing can be a challenge due to the fixed aperture of most (all?) phone cameras. If your phone has different cameras on the back, look up the specs and see if one has a higher aperture, then try that if you're struggling with focus. Plus if you use it with a phone that has an optical zoom telephoto lens, you can increase your total magnification even further.The built-in lights are also really really handy, because you have to get so close to the subject that you wouldn't have much light on it otherwise. Charges easily with USB-C and the ability to lock the frame position and then just clip out the lens to swap in one of their other ones like the 200x is really really handy so you're not needing to reposition all the time.
