And if using the camera (obviously not the R6 or R6.2) on automatic, this will cause an error. Ergo, the eyepiece shutter. The mirror does a good job of blocking viewfinder light during the exposure. It is light tight. I have no clue as to why the R6 and R6.2 have the eyepiece shutter. I suspect it was more work to leave it out, plug the holes, than to just leave it in. Roger... you needn't scratch your glasses. Jim
