SEL-35F18 as a main travel lens? Stills + video?

Total amateur here... I've been learning my way around NEX7 and Zeiss24 for a few weeks. Love the stills but can't quite get the videos to come  out smooth.  With upcoming overseas trip I am worried I won't get the videos to come out to my expectations so I am considering SEL-35F18 for it's OSS as my main lens for this trip so I don't have to keep switching lenses on the go, suggestions?
