To provide an answer to when these are needed, our application of varifocal is having the lens in a wider view during the day when lighting provides the best results. Then as the light fades, we use presets to move the camera to have a image of the most important scene elements; door, gate, etc. We knowingly sacrifice the view of the open areas, in exchange for the critical areas. We do this with single lens varifocal cameras, and doing that with a multi-lens makes sense too.

Add some varifocal aware stitching and you have a poor man's Dallamier Panorama.

I have been hearing about this for abou a year now.
The old models were too expensive and not that good (image quality).
Also have you seen this:

The original panoramics (available since 2009) have grown stale, and I look forward to working with these.
However, with a multi-sensor (3 or 4) camera, the tendancy is to visualize the camera mounted on the X or the y axis. By adding a variable mounting angle, my mind is now blown as I architect camera placements for the aisleways of a 1mil. sq./ft. factory with many 3 and 4 way intersections, all while maintaining a minimum image requirement and 100% coverage.
The tools we developed are getting a workout as we consider mounting cameras at off-angles with the 3rd sensor either above or below the two. Then rotate one or both outer lens and capture on the 3 x 4 axis, while we capture the 3rd sensor on the 4 x 3 axis. This opens up a lot of possibilities to have cameras overlap coverage and minimize camera counts.
Don't forget, we can also Mount the 4 sensor at 75 degrees, where the bottom sensor can capture on the 4 x 3 axis (93 degree HFOV) looking downward , the outer and upper sensors on the 3 x 4 axis to the left, right, and forward, at a narrow (24 degree HFOV.)
I expect this to be my new favorite camera if I keep my sanity.
