So I now hve this lens which if you are debating about getting based in the mixed reviews, don't wait. It is a really great lens and has plenty of character, super fast autofocus and perfect fov (if you like 35mm equivalent). Anyway it has great manual focusing potential and to be honest I have never manual focused before so can anyone give me a heads up on how to set it up? I guess I want to be able to use autofocus but if the desire arises snap the ring back an manual focus. Would be good if it could automatically zoom in to the area so I can focus in detail. Any hints, tips or advice to do this would be great.
