Wide lenses require fewer steps to get the full sweep than longer lenses do.
For example, my 24mm lens requires 12 steps to make a full circle. By contrast, a 28mm lens requires 16 images to do the same. I choose which to use based on the focal length of the lens attached. The number of steps you'll need for a panorama depends on the focal length of the lens you use, as shown in this table. FOV is field of view, the angle of the image captured by the lens.
