Not compatibleUse the shared name only where the table supports it
The X5 / X4 Air Quick Reader and X5 / X4 Air Mic Adapter are both supported for Air. The separate X4 Quick Reader and X4 Mic Adapter are not. The word X4 in the camera name is therefore not enough to select an accessory.
Match the whole product label at checkout. A truncated “X4 reader” listing leaves out the distinction the manufacturer’s table makes.
Air-specific protection and charging remain separate
The X4 Air Utility Fast Charge Case is supported; the X5 Utility Fast Charge Case is not. Likewise, the X4 Air Standard Lens Guard is supported, while the X5/X4 Lens Cap is not supported for Air.
These are exact fit statements. They do not establish that every item sold under an Air-compatible marketing label has the same construction or protection. Use the matrix for the listed pair and the named accessory’s instructions for its actual use.
