Add a support for your PL lens adapter when mounting it on a Tiltaing cage protected Sony a7S III with this PL Mount Lens Adapter Support for Sony a7S III, in a black finish, from Tilta. The adapter support mounts on the front of full or half a7S III Tiltaing cages (not included) using the included mounting screws to keep the weight of your adapter and lens from stressing your camera's lens mount. Aluminum and steel construction keeps this both lightweight and strong, while the black finish helps protect from corrosion.
