I don't like "just" 80mm or 100mm lenses. I know some folks swear by them and rave about them. If I'm in a room I can't take a picture of somebody in the same room. I have to back out to the door or further. They have their uses and may be great lenses overall, but if that's the ONLY lens you get you'll find it limiting. Or, at least... I would find it limiting.
