Hi Eugene, Here's a simple way with an expression: 1. Give your camera a custom parameter (CPSet is called Vertigo, hence *Camera.Vertigo.width_at_interest)* to define the width at the interest that needs to remain static.
2. An expression on the camera FOV: *atan( Camera.Vertigo.width_at_interest / ctr_dist( Camera., Camera_Interest. ) ) * 2* That should hopefully do what you want.
