Not compatibleReader, charger and lens protection need their own checks
The X3 Quick Reader, X3 Fast Charge Hub and X3 Lens Cap are supported in the X3 column. The named X4 reader and charging hub are not. Buying against “X Series” alone misses these distinctions.
The X3 Premium Removable Lens Guard is also supported. This names a particular protective accessory; it is not proof that a guard described only as fitting a similarly shaped camera has equivalent compatibility.
Shared accessories are explicit, not inferred
The X Series USB-C Cable and X Series Cold Shoe are supported for X3. The X Series Upgraded Invisible Mic Cold Shoe for RØDE Wireless GO is also listed as supported. Keep that full cold-shoe name distinct from other mic adapters or mounts.
The matrix records the manufacturer’s stated support for these items, not a test of every third-party substitute. An unlisted product remains an open compatibility question.
