Its optic is right up there with the Nikon SE, and it solves a lot of the other issues I have with the SE, such as waterproofing, focus speed, focus stiffening in the cold. I do have one problem with my sample of the EDG, though. When I first got it several weeks ago, the correct diopter setting for my eye was at the +1 mark, same as where I set the SE's diopter. But every time I used it since, I had to increase the + diopter adjustment. The first couple times it happened I just thought I remembered wrong and/or it was my eyes on that day. But now I have to set it to past the +4 mark to focus correctly. It can't be my eyes because the SE still looks good at its normal diopter setting. So it seems like the diopter adjustment creeps steadily towards one direction (by my calculation, it's roughly +1 mark/week since I noticed the problem). Once adjusted correctly, the diopter stays where it's set for the day, but I'll have to readjust it if I use it several days later. I don't understand. I thought everything in there was geared so no creeping like this could happen. Maybe there are belts in there or some friction fit in there that is being pulled out?  I'll ask Nikon to repair it, but would like to get some insight why this could happen before I send it in. Thanks.Ning</blockquote>
