I once posted some viewing angle figures for 35mm camera lenses (on the Wings forum) - but can't find them :) A 50mm 'standard' lens (one that used to come with the (SLR) camera - in previous days) has a (diagonal) viewing angle of 46 deg. This was supposed to give a view similar to that perceived by the eye. More recently, a 35mm lens has become more 'popular' - view angle for this is 63 deg. (Typical focal lengths for taking 'portraits' are 85mm - 100mm - with corresponding view angles of 28.5 and 24 deg respectively) Depending on what's being modelled, it might be worth messing around a bit? :) (Lens details from Canon EF series, btw) pp
