What is the best way to render fullscreen elements

Hello.

During render i can change camera settings: fov, rotation. But i have group of elements, which should be rendered with fixed camera parameters. As the result, i need to have different camera settings for different objects during render.

What is the best way to do this?

I want to render all in one view, For now i see only one way to change camera settings in material.

Something like this?

I was able to make using several viewports. For each viewport i setup camera and copy result of first viewport to second viewport.
