Re: Canon f/2.8 300mm IS USM II - How to set to "0" again

Logically it sounds like the AF is just reacting too slowly - which is a new and not normal phenomena - so unfortunately as you say must go back to Canon or find a reputable equivalent....

have you you tried calling either lens rentals or even b&h and asking their advice or where they would recommend?
