# ZOOM VALUE CALCULATIONS:
#
# Given values:
#     - sensor width (camera.data.sensor_width)
#     - sensor height (camera.data.sensor_height)
#     - sensor fit (camera.data.sensor_fit)
#     - lens (blender's lens in mm)
#     - width (width of the composition/scene in pixels)
#     - height (height of the composition/scene in pixels)
#     - PAR (pixel aspect ratio)
#
# Calculations are made using sensor's size and scene/comp dimension (width or height).
# If camera.sensor_fit is set to 'AUTO' or 'HORIZONTAL' - sensor = camera.data.sensor_width, dimension = width.
# If camera.sensor_fit is set to 'VERTICAL' - sensor = camera.data.sensor_height, dimension = height
#
# zoom can be calculated using simple proportions.
