SmallRig 17mm Threaded Lens Backplate for the iPhone 13 Pro Max Mobile Cage

Designed for their iPhone 13 Pro Max Cage, this 17mm Threaded Lens Backplate from SmallRig replaces the cage's original M-mount backplate, enabling lenses with a 17mm thread to be used with your iPhone 13 Pro Max. The backplate is secured in place using three screws, and its design does not block any of your phone's integrated lenses.
