I have been looking around the web, and it appears that you are right regarding the wide angle lens. If I am interpreting the other websites correctly, the problem is that I am standing too close. However, if I stand further away, then I would have to crop it in photoshop (which sucks, since I want to post them right away).
Supposing moving further away is the fix, would zooming in be ok, or would that cause the same problem to occur again?
I am also wondering if there is a system (amount of zoom, distance from the subject) that is ideal for this.
