A prime (fixed focal length) lens is set to one mm focal length. In other words, the focal length cannot be adjusted. If you want to get more or less of the scenery or object in the photograph, then you need to physically move yourself in or out.

However, there are times when physically moving yourself closer or further away from the subject isn’t a possibility. For example, if you were on a whale watching cruise, the restrictions of a prime lens would be useless. For times like this, a zoom lens would be more beneficial.
