The Canon 100-400 II is one of the greatest zooms out there. It is however, IMHO, NOT a walk around lens I would want to carry all day. But for a 1/2 to hour walk, no issues.
Depends on health.
I do carry it all day if needed. But I do not climb mountains for a whole day. I usually stop, look sit, eat and do other things on a day out and about.
