Mac, you just helped with one of the most frustrating things for me ... no keystroke for the aux cam. Thanks for the tip! I find the aux cam to be really helpful when creating new spotlights. As a point of interest I've read in a few places that 55mm approximates how the human eye sees. For most of my medium-length shots I use 90mm. 105mm for portraits. As karen1573 said, 25mm can be fun to play with ... I think of it as the "fisheye" setting.
