The light is only in the viewfinder and backlights just the LCD display. No aperture information in any OM viewfinder.

I had a odd thing happen the other day. My display was dead when I brought the camera up to eye level to take the picture. I lowered the camera, reset the camera, looked through the viewfinder and it was fine. Went to take the picture and the display disappeared again. After a few moments of puzzlement I discovered that I had my left hand over the top and my finger was blocking the window. Only time in years I've done that.
