For the X-E2 provides Mengs yes to a new version:
Since the X-E1 and E2-X have the same basic shape, this grip fits naturally also to the X-E2.
By the handholds I can hold the camera perfectly. Together with a thumb grip, the perfect combination.
Whether the handholds are pleasant, of course, depends very much on the "tree shape" of hands - for me it fits just fine.
Who is not sure, maybe you should consider the version of the X-E2 into consideration.
