>>3239761>Also you can safely use a 2x TC II or III with the 70-200 if you're looking into wildlife so no real need for the giant dustpump 100-400.That's not true. The 100-400L was a known Dust sucker due to the push-pull operation of the lens and lack of seals. The newer 100-400L II has an internal seal and a different method of operation. Canon (and users) claim it's pretty immune to dust now.
