How do you use preview Mode on E-500
I don't know how to utilize this feature on the E-500. When I enable to preview button which I have assigned to the one touch white balance button, I can see the image in the view finder dim or brighten. Is this just to show me the affects of the apeture setting. I read the manual which seems to imply that it previews the depth of field, but I do not notice this difference.
