Hi! PL-WD02 will be great for selfie with effect similar to fish eye. PL-WD01 will give slightly lesser wide angle. Our PL-WD07 is also great for wide angle, but slightly bigger in size.
They have distortions though, as they are wide angle lens. As for the black rims they have minimum black rims to none, especially for iphone 7 as the lens fit perfectly to the iphone 7 camera. You can start first with either PL-WD02 for more extreme effect, or the PL-WD07 for lesser extreme effect for selfies :)
