The 55-200 is my least thought of lens. Sitting in the bottom of my bag of lenses I really only bring it out when I go to the mortocross track. There I basically beat the crap out of it, letting it get dusty, wet, using my sleeve to wipe of the dust... and everytime I walk away amazed at the quality of the images! Mind you, in insufficient light, it's another story but when light isn't a problem this lens is fantastic, especially at the price!
Here are some pics of a Red Bull Rocks and Logs event this weekend. Ideally, you want to have the rider coming at you but unfortunately due to the limited access for spectators we were unable to see them coming for the good parts!
