Despite some of the warnings about Amazons packing on this lens, I went for the lowest cost and tried again (better packing with other lenses) with a new EF-S 17-55mm. The carton showed-up today. A large box, deflated airbags and my new $1000 lens in Canon's carton bounced around. I can not believe Amazon hasn't a clue on packing/shipping these lenses. Fortunately, it seems my lens is OK, but this is the last of several purchases I will make direct to Amazon.com.
