In a camera viewport, the FOV button lets you adjust the field of view
interactively.
The camera viewport Perspective button also changes the FOV in
conjunction with dollying the camera.
NOTE Only the FOV value is saved with the camera. The focal length value
is merely an alternative way to express and select the FOV.
To set the camera lens size:
1 In the Stock Lenses group, click a button to choose a stock focal length.
2 Set the Lens spinner to a custom focal length.
TIP If you want to maintain the same lens, avoid using the FOV or Perspective
controls among the navigation icon buttons, and don't change the FOV
spinner.
IMPORTANT When a camera viewport is active, changing the Output Size
or (custom) Aperture Width in the
Render Setup dialog on page 6067 will
change the camera's Lens setting.
To match a camera to a film or video format:
1 On the Render Setup dialog, in the Output Size group
Output Size group
on page 6124, choose the type of output you want. Use either of the
following methods.
■ Choose a preset, such as HDTV (video), from the drop-down list. The
Aperture Width is locked to the preset's values.
■ Choose Custom and then set the desired Aperture Width value. (You
can adjust the other output values at any later time. They have no
affect on the camera lens settings, although they do affect the cropping
of the scene.)
2 After setting Aperture Width, set the Lens value for the camera to the
type of camera lens you want to emulate (for example, 50mm).
To maintain the same lens, avoid using the FOV or Perspective controls
among the navigation icon buttons.
