Works perfectly with the XE1 and offers sufficient power especially as the XE1 can work at high ASA. Only complaint, but not due to the flash, the position of the XE1 speeds barrel; the flash fixing wheel speeds covers the barrel and in particular the index thus preventing to see the speed displayed at the barrel. The barrel can be rotated and however we can control the speed display in the viewfinder. Note that regardless of the flash attached to the claw we will this problem due to the position of the barrel of the XE1 speeds ... and surely other series devices. No prohibitive use.
