It has long been rumored that the iPhone 11 Max will have a triple-lens rear camera, but if you need any more evidence of that then a new accessory provides it.
A camera protector for the phone has been listed on MobileFun (a mobile accessory retailer). Built by Olixar – which is a reputable brand – images of the accessory show spaces for three lenses. In fact, the iPhone 11 Max itself is also pictured, with three lenses visible, along with a likely quad-LED flash.
