Actually, if you do a web search, Charles Cramer, a noted California photographer, uses the 55-110 for landscape photography, albeit with a digital back. Often, it is very useful to use the zoom to crop/compose, versus using a fixed focal length.

I sold my 105-210 because of where I was living at the time, it wasn't that useful. I still do have 45, 55, 80, 120, 150, 300 lenses.
