For panoramas I generally use my Nikon 24mm shift lens. I take three shots, (left, center, right) and stitch in PS. This works very well for waterfalls too by shooting vertically. Since I'm used to using the movements on an 8x10 field camera the Nikon shift lenses are a perfect fit for me. Yes, it takes time to set up and level a tripod, use the camera in manual mode (to keep exposures the same in all three shots), and take three photos. I think extra care results in photos that have a different look from what the other thousand people took of the same place that day.
