Ockham, I'm pretty sure that focal lengths in Poser, as with those quoted for digital cameras, are the equivalent focal length that would give that angle of view on a 35mm camera. Momodot, there's several options within Poser 5. See the Guides sub-menu, right at the bottom of the Display menu. There are some optical problems with wide-angle on digital sensors. It's not hard to make the short focal-length lens that gives the angle of view with the small digital sensor. But the digital sensors struggle toi pick up light coming are axtreme angles, so the optical design gets more complicated. SLR cameras have to use the same tricks to make room for the mirror, but they don't have zoom lenses which go to extreme wide angle.
