I have always used Nikons, but I think either of these cameras will work just fine for you. One note on the Nikon G lenses, the G designation only refers to the lack of an aperture ring, which you won't use on the F80 anyway. They started out as the cheapies, and you do have to watch out for those, but some pro or near pro level G lenses have now been introduced that are very nice lenses. I would also consider avoiding the kit lens that is available with the camera (likely with either camera), at least take a good look at it, the plastic lens mouts are really not meant for someone who will really change their lenses very often.

Have fun!
