I know what a kit lens is, but I am wondering what a standard kit lens is. There is a post for what a kit lens is, but I couldn't find a post on standard kit lenses. Standard or normal, in general, is the lens which sees quite like the human eye, in terms of field of view. This depends on the size of the image sensor. For example for a 24mm x 36mm sensor (full frame) the normal (standard) lens is 50mm.
So what is a standard kit lens? For example, why the 18-55mm is a standard kit lens?
