SmallRig 67mm Threaded Filter Adapter for iPhone 18 Pro 6906

The SmallRig 6906 threaded filter adapter adds a standard 67mm filter thread to SmallRig video cages for the iPhone 18 Pro. It mounts on the cage's lens backplate and releases again with the Unlock catch, so the phone accepts ordinary 67mm filters — polarizers, ND and variable ND — in a moment. SmallRig offers its own TrueColor 67mm Hybrid VND filters 6896 (1-5 stop) and 6897 (6-9 stop) to go with it. The aluminum alloy body with a silicone seat is 6.4 mm thin and weighs 19.4 g, so it barely registers on the cage. This version belongs on cages and kits for the iPhone 18 Pro; the iPhone 18 Pro Max takes adapter 6907. Do not use in environments with strong acids or alkalis.
