Title: Not for E-3 or E-5
Review: Bought this for improving the viewfinder experience on my E-5. The eyecup installs painlessly (although with a lot of friction). However, if you pay attention, the exit pupil of the magnifier is much smaller compared to that of the camera's eyepice, and so your field of view through the SLR system will be limited. With glasses, it's just borderline unusable. Without glasses, you have to press your eye very close to get the benefit (and it's a nice benefit). However, the materials this product is made out of tend to reflect and flare, putting glare into your eyes. Not cool. Needs protection against stray light.
