In my opinion all Canon products at release date are to much overpriced. After 1-2 years prices become more or less normal, however, still much higher comparing to such companies as Tamron and Sigma. Maybe some time ago Canon and Nikon were only two leading companies in lens production, however, latest test show that Tamron (especially with their SP 24-70 mm 2.
and Sigma can compete with quality, however, their prices ar much lower.
In my opinion, Canon has a very good and quite loyal custormer base, however, people do not like to be screwed and, if Canon pricing does not change, then they will start loosing to other lens producers. I still have an biased opinion that Canon and Nikon cameras are the best, however, Sony, FujiFilm and other manufacturers are trying to change that concept in people's minds... especially whn mirrorless cameras are becoming more and more popular. Nikon and Canon can not boast having strong positions in this rapidly evolving segment.
