I'm doing with my Canon 50D and 600D annually about 30,000 recordings. Most of events (Free Press employees), but sometimes nature pictures or portraits. After I had been annoyed enough with the lenses 18-270 (insufficient light intensity, no quick release) I put me two years ago to the 24-205 and have not regretted the investment. Whether at concerts in Festhalle or church, at press conferences (1-second handshake) - no longer a problem. The camera will perfectly "to the point" from. A small disadvantage is (for my work) the lack of specific perspective. Will be resolved shortly Duch purchasing the 17-40 lens. This course is only the L USM in question. Quality has just now times their price. ahu.
