There are so many types of photography that a photographer can indulge in
, that lenses automatically become an integral part of the whole process. Aerial photography would require different lenses, wedding photography would have different lenses being fitted in, and portrait photography again comes with a different requirement and the same augurs for fashion photography as well. So in the midst of all these types that a photographer does to make himself versatile, debating whether the lenses will be useful or not is an exercise in futility. They have to be there to make a difference and make the pictures look as they should be.
