adjusts the amount of the scene that is visible in a viewport and
the amount of perspective flare. The effect of changing FOV is similar
to changing the lens on a camera.
- As the FOV gets larger, you see more
of your scene and the perspective becomes distorted, similar to
using a wide-angle lens.
- As the FOV gets smaller, you see less
of your scene and the perspective flattens, similar to using a telephoto

Although the effect of
Field-of-View appears similar to a zoom, the perspective is actually
changing, resulting in increased or decreased distortion in the viewport.
In a Perspective viewport,
Field-of-View defines the width of your view as an angle with its
apex at your viewpoint and the ends at the sides of the view.
In a Camera viewport,
Field-of-View controls the width of the area a camera views, and
represents the arc of the camera's horizon in degrees. For a selected
camera, you can adjust its
and Lens parameters directly to fine-tune
the FOV you set in the viewport. See “To use FOV with Camera parameters”
in the following procedures.
To adjust the field of view in a viewport:
- Activate a Perspective or Camera viewport.
- Click Field-of-View.
The button highlights when it is on.
- Drag in the viewport to adjust the FOV
- Dragging down widens (increases) the
FOV angle, reduces lens length, displays more of your scene, and
- Dragging up narrows (decreases) the FOV
angle, increases lens length, displays less of your scene, and flattens
- To turn off the button, press Esc or right-click.
To enter an FOV value in a Perspective
- Activate a Perspective viewport.
- Right-click (Field-of-View)
to display the Viewport Configuration dialog.
- Click the Rendering Method tab.
- In the Perspective User View group, enter
an angle in the FOV field.
- Click OK to make the change.
To use FOV with Camera parameters:
- Activate a Camera viewport.
- Press H and
select the viewport’s camera in the
- Go to the Modify panel to view the
camera’s Parameters rollout.
- As you drag Field-of-View in the viewport,
the FOV and Lens parameters update interactively.
- Set the FOV and Lens parameters directly,
or click a button in the Stock Lenses group.
Only the FOV value is saved with the camera.
The Lens value (focal length) is another way to express and select
in a Camera viewport also changes
the FOV in concert with dollying the camera.
