I was thinking about different lenses and I am not sure why somebody would want a fixed zoom lens compared to a zoom lens. There was a post I found in the search, but it didn't really give any reasons why one would be preferred over the other. Is there a difference in the quality? Thanks for any help!

Fixed lenses usually give better quality, wider aperatures, and are more rugged, or at least I'm told. Compare a 400mm F5.6L Prime to a 100-400 at 400mm at F5.6, and the difference is pretty significant... plus, the 400 F5.6 is gonna last a lot longer (it shows, as they were discontinued a while ago, and the beat up looking ones one ebay still pump out awesome shots).
Using primes is more fun, too.
