Good evening, firdaus. First off, please change your display name to your full first and last name as per the forum rules.

 

The field of view shown with a given focal length will change depending on format. For example a 35mm lens on spherical 35mm will have a horizontal angle of view of 33.4º. Put that same lens on Super 16mm and you get an angle of view of 19.1º. Furthermore, put that exact same lens on a 2/3" inch video camera and you have an angle of view of 15.6º.

 

Each format is just using a different part of the cone of light projected by the lens.

 

I calculated these numbers with Panavision's Image Calculator. There are also tables with this information in the ASC Manual.
