Of course, "film" doesn't have to mean "manual focus". But in general, I think it's usually a mistake to be too principled about "film only"; you want to use the right tool for a particular job, right?---and sometimes that means using something that's not your preferred tool.
I am going in a short beach trip tomorrow and i am only bringing my film camera. This is the first time going on a holiday with no digital camera. I want to use this as a stepping stone to see if i can survive with film in my more important Canada trip this August. I cant tell you how stress i am. My family members expect me to still take those nice family shots of the kids etc. At this point in time i cant even manual focus on the kids. They are almost impossible to take!! And now suddenly i worry about exposure which never cross my mind before.
