iPhone 12 Pro Camera Protection

With clear, anti-reflective glass there is no visible difference. Only cheap, cloudy covers can cause glare against the light. Flash shots come out better when the cutout leaves the flash clear.

Individual rings add less height and leave the flash clear. A single cover also protects the area between the lenses and looks more uniform.

Yes. Many iPhone 12 Pro cases already have a raised lip around the camera area; a separate lens protector adds to it right on the glass.

The case protects the frame, but the lenses often sit beyond its edge. For phones set flat a lot, the extra lens protector is worth it.
