Lens attachments for your iPhone can bring a fresh point of view to your photos but there are drawbacks. Some force you to remove the phone’s protective case to properly fit the lens. Others require a sticky mounting plate.
The mount for the Iris lenses by Photojojo looks like a little girl’s ponytail holder with a silicon housing holding one of three pop-in lenses that is attached to an elastic cord stretching and securing snuggly to diagonal corners of your iPhone or Samsung Galaxy.
