I've just bought this camera and the lens, and I feel so silly; I don't know how to zoom. Do you know how? When I turn it on it seems to be zoomed and I would like to zoom out.
You can’t. The 50mm f/1.4 is a prime lens, which means it has a fixed focal length, or fixed field of view. This is what some people call a “sneaker zoom” lens, where you as the photographer have to physically move to change what you see in the viewfinder. See mattdm’s great response in this question.
