OM-D built in rubber eyepiece coming off?

Thanks everybody. Very helpful. I'd like to keep the size of the camera as small as I can so it fits easily in a pouch and I haven't had any issue with visibility in sun via the included rubber eyepiece. So I am trying gluing it in place and I'll see if that works.

Looking at it I am guessing it is intended to come off so that it can be replaced with the accessory eyepiece. Is that right, those of you who bought the add on eyepiece? Or does the add on eyepiece fit over the included eyepiece.?

This would be good for those who might want the add on eyepiece to know.

regards

Peter
