If you haven't been in Tokyo before, prepare to get stressed out in the Shinjuku-area, just getting out of the train/subway station can be a challenge, after that, the real challenge navigating the area begins....so take your time, smile and laugh about how often you get lost
The Ginza-strip is imo the best place to start, it's just one main-street and all the camera-shops lies there, or in one of the side-streets, very easy to navigate.
