If you attend any of their events, courses and workshops it can be worth while because there is a member discount and there are several meet-ups and zoom talks that are free for members. If you enjoy looking at photos their journal, which is now bi-monthly, is pretty good, I always like browsing through it and compared to other high-quality magazine subscriptions that on its own is reasonable value. Finally it is like a very large, national camera club, so again if that is your sort of thing then why not. To some extent, like a lot of things, you get out what you put in.
