Also, be aware that the UV filters are necessary to complete the weather sealing of the lenses.


Furthermore, as Brant stated be aware that the 10-22mm and 100-400mm are not weather sealed. John and I were discussing this a couple of weeks ago; the 100-400mm is sharper from 200-400mm over the 70-200mm when it is used with the 2x extender, and the 70-200mm is sharper from 100-200mm and is especially sharper from 70-100mm.
