Just read the June 1975 Modern Photography review of the XE-7 and it extolled the smoothness and quietness of the camera. I've always said the XE-7 has to be experienced. But beware, you might think there is something wrong with your camera after trying out the XE-7 . . .
You're not wrong! I had an XE-7 that had metering issues. I didn't want to mess with it so I sold it. I still have the XE-5 and the smoothness of winding is something to experience.
