I have really enjoyed taking photos with this lens. I tend to shoot fast moving subjects, such as model airplanes, and it has given me great photos. I wish it had a lock for the 500mm, but that is trivial. The weight of the lense is a definite factor if you are walking for a while and don't have a place to set it down. At 4 lbs., it is quite a bit carry. I have chosen it to be one the main lens that I carry all the time. I bought this for the 500mm as well as the 50mm capability. I have the 400mm IS lense,500mm lense, the 170-500mm lense, and a 600mm lense and this is the best of all that I have purchased. I have photos at http://www.pbase.com/nc911/011407_flying_rc_planes if you would like to see what I captured. John
