A normal lens will be your basic lens that most photographers start out with. This lens will give a field of view that appear natural to the eye of the viewer. Long or short lenses would be expanded, therefore being distorted from the “normal view”. This type of lens is a fixed focal lens, also meaning it can not zoom in. Yes, this is a lens that you will start out with but it is a learning lens, it is for you to experience what photos look like in real time. This type of lens has advantages too, it is normally a faster lens, meaning the maximum aperture is very wide. Meaning pictures in a lower light with a faster shutter speeds. I suggest you do not knock the “average” until you’ve tried it!
