Yes thats true, I have 4 XE-7s

But something is not working correctly in this case.But its an easy fix,most likely the lube dried out and is gummy holding that lever/lock away from the cam that lever holds the other lever in a position that won't let shutter fire.

Thanks Bearman, I try to help.Some of these problems with older cameras are simply dried up lube.Loosening with a little naptha or lighter fluid can restore normal operation.
