I ordered a 100-400L on Black Friday (used from LensAuthority) and it just arrived today. I can't wait to get out and shoot with it. Unfortunately the weather isn't going to cooperate this week where I'm at (up in Minnesota).
Quick question about the lens:
Is it normal for the zoom-tightening ring to turn the manual focus ring as well?
It doesn't seem like a problem and as I examined the lens it looks like this is inevitable based on the design. I just wanted to check, since I have a 3-day inspection period. Since I got it from LensAuthority, I trust that it was well examined before being sold. Everything else seems to be in good working order.
Thanks for the feedback.
