BlenderDiplom has a look at the new Camera Widget in Blender 2.8.
New Blender 2.8 development gets a new in-view widget for the camera object in the scene. BlenderDiplom’s Gottfried Hofmann walks through the new feature and shows how easy it is to change camera attributes right in the viewport.
The new camera widget in Blender lets you change focal length by clicking and dragging the camera frustum representing the camera plane. You can also activate other features like changing the focus distance using the widget in the scene. Varying attributes for things directly in the view like this is a big help for adjusting critical elements. “the developers of Blender 2.8 have even more in store…” Hofmann says.
