This might be a hard challenge but it would nice to be able to have a Linear camera option as an alternative to Turntable. It might be easier to do Zoom+Turntable Rotate with speed settings for each.
The other way could be simply adding a speed control instead of snap when using "Move to Origin (Gizmo tool). This would semi-simulate animated cameras.
For instance: Move (?) every (?) seconds
Move (?) when view renders %100
This feature would make it easy for green/blue screen video projects considering ACES and Tone Mapping are a feature.
