Take great Macro photos without an extra lens.
One of the cool features of Camera+ is the ability to take Macro pictures. This works in both the Camera + version and Camera+ 2 version.
Users can get up very close to an object and take a close up photo:

When using the Macro lens in Camera+ you are using the telephoto lens. The telephoto focal lens is 6 mm, which is equivalent to a 52 mm lens on a full-frame camera.
This means that you can get your iPhone XS Max up to 6 mm ( or .23 inches) to an object and get a nice clear focus.
Camera+ App better than Extra External Lens
You can buy an external lens to take Macro photography, but I think that the Camera+ App does a pretty good job taking close up for most situations.
By using the Camera+ app, It's a great way to get really close to an object without having to buy some third-party lens extension. Which works well, but you have to remember to bring it and in some cases you would have to take the phone out of the case.
