You usually carry your smartphone around with you. Sometimes you want to examine something more closely, but it's a little too small to see with the naked eye. Unfortunately, when you use your phone's camera, you can't get close enough to get a good look at the object. Then, as a last resort, you use the digital zoom function. The image will get bigger, but it will be blurry and look very rough.
When you attach a macro lens in front of your phone's camera, you can get much closer to your subject and see it much larger. It doesn't matter if you have a splitter in your finger or want to thread the thread into the needle – you now have gained total control and a complete view of everything.
You can effectively use the technical potential of your smartphone, such as slow motion or time lapse. You don't need a PC to edit the pictures, your mobile phone offers you almost endless possibilities.
