As Canon became the big dog on the lot they made a lot of lens, from a simple supply and demand, lots of supply, add Sigma, Tamron and Tonkica many to chose from. Of course with very long lens, some very fast and long lens the price quickly climbs. What is more inexpensive is Minolta A mount, some very good glass goes for very little.
