It is incredible. I already owned the 180mm L macro when I ordered the 100mm. For the most part if I am doing macro with a tripod I am using the 180mm, and the 100mm is great for chasing fast insects hand held. It really opens up allot of macro opportunities that you would have a problem doing if you had to use a tripod.
