Lens Sets the camera's focal length in millimeters. Use the Lens spinner to
give the focal length a value other than the preset "stock" values on the buttons
in the Stock Lenses group box.
Changing the Aperture Width value on the Render Setup dialog also changes
the value in the Lens spinner field. This doesn't change the view through the
camera, but it does change the relationship between the Lens value and the
FOV value, as well as the aspect ratio of the camera's cone.
FOV Direction flyout Lets you choose how to apply the field of view (FOV)
value:
■
Horizontal (The default.) Applies the FOV horizontally. This is the
standard way to set and measure the FOV.
■ Vertical Applies the FOV vertically.
■
Diagonal Applies the FOV diagonally, from one corner of the
viewport to the other.
FOV Determines how wide an area the camera views (
field of view on page
7972). When FOV Direction is horizontal (the default), the FOV parameter
directly sets the arc of the camera's horizon on page 8005, measured in degrees.
You can also set the FOV Direction to measure FOV vertically or diagonally.
You can also adjust the field of view interactively in a camera viewport on
page 7604 by using the FOV button.
Orthographic Projection When on, the camera view looks just like a User
view. When off, the camera view is the standard perspective-like view. While
Orthographic Projection is in effect, the viewport navigation buttons behave
as they ordinarily do, except for Perspective. Perspective function still moves
the camera and changes the FOV, but the Orthographic Projection cancels
the two out, so you don't see any change until you turn off Orthographic
Projection.
