I know I'm in the minority, but I sure hope the 100-400 replacement is a push-pull zoom.https://www.google.com/?gws_rd=ssl#q=advantages+of+push-pull+zoom+lens
At least two of us in that minority...
I have wondered about the pros/cons of push/pull zoom and found this link, which mentions the 100-400
Interesting discussions with personal preference perhaps a factor. I think the push/pull design has made way for the rotating ring mostly because of recent advances in autofocus. And just maybe the rotating ring may cost less to make??
