It is enough. If you feel youre missing out, get a basic dslr and dedicated macro lens. Your pics will exceed the quality of these by leaps and bounds.
The iphone 13 pro macro has (imo) pretty severe distortion along the edges and must be positioned so close to the subject that it casting a shadow with the phone and light problems are inevitable. A dedicated macro will be more uniform with no distortion, will likely allow for better magnification with some tweaks, will focus from farther away therefor avoiding light problems, and will overall be sharper and resolve better.
The iPhone 13 pro’s macro lens is very nifty, but it is just not a pro camera tool.
But it *is* very nifty!
