Yep, for Universal, I use a fanny pack. No need to use lockers. I use a small point and shoot or phone as my camera, as both fit in my small fanny pack. If I'm not doing the put in locker rides, then I carry a string bag and use a lanyard for my tickets, id, credit card and money.
For WDW, I do a small cross body, and put a string bag in it for my bigger camera, so when I'm tired of having the bigger camera on around my neck or one of my kids' don't want to carry it, I put it in the string bag. We go when it's very hot, so the less to carry the better.
