The vertical alignment can be adjusted without disassembling the camera top cover. However, the same adjustment can be performed with the top cover off or the RF assembly extracted.

Remove the adjustment screw cover by rotating it with a lens wrench or custom tool. Note that uses a bayonet mount with no threads, so at most 90˚ rotation is needed.

Adjust the vertical alignment as needed. The same adjustment screw is used when adjusting in a more disassembled state.
