That's interesting. When I started wearing glasses, I always had to choose shoot without my glasses (I can adjust the diopter on the OVF just fine) but then I can't see the LCD to chimp shots and adjust the menus. Or, I could wear my glasses so I can see the LCD, but then constantly clean them because of the eyepiece grunge on my glasses.
The K-01 solves that problem for me (well, actually, the Pen solved it first). Now, I can wear my transition glasses, I can see the LCD and menus, and I don't have to worry about eyepiece grunge on my glasses. My polarized sunglasses even work (they're prescription) until I turn the camera to portrait. So I take a lot of portrait shots outside with my head tilted.
