Add additional camera presets In blender we have a camera presets selector. 



Some of the items are quite old now and there have not been many new additions. How would one go about adding new presets and what information about the camera would be required?
You just need the dimensions of the sensor.

Put those on the sensor width or height.

Then use the plus button (+) on the right of the preset to create a new one, and name it whatever you wish. 

To delete the presets you don't need, use the minus button.

Presets are a .py file located in the Scripts folder within the blender progra's folder. In windows they would be in

C:\Program Files\Blender Foundation\Blender\2.78\scripts\presets\camera.

As an example, this is the preset for a Full Frame camera:

Full_Frame_35mm_Camera.py

import bpy

bpy.context.camera.sensor_width = 36

bpy.context.camera.sensor_height = 24

bpy.context.camera.sensor_fit = 'HORIZONTAL'
