I didn't do a lot of reading, but it sounds like an anamorphic lens can capture more image data, allowing you to zoom in more in post processing. Check the attached article and others if you like.
Moment made an anamorphic lens for the
Mavic 2 Pro. It was a nightmare to use because it had to be reinstalled every time the battery was changed, onto the already powered up gimbal, as the gimbal couldn't balance with it already installed. Required a huge counterweight on the back. Gimbal would then spontaneously go limp during flight from the excess weight, requiring landing and reinstalling again!
However, its purpose was to capture a
wider field of view rather than a narrower one. Once captured, the wider field of view had to be separately uncompressed in proprietary software before it could be used for editing.
DJI has already created a wide angle lens for the
Mavic 3. I own it. It isn't anamorphic, but it does give a wider field of view, which unfortunately is the exact opposite of what Tiger wants.
Tiger wants to add an optical zoom to the 4/3 camera lens, and have the existing gimbal still balance it. Never going to happen. See above for the Moment nightmare lens attachment.
The reason that DJI has only made one zoom lens on all their consumer drones and only on a 1/2.3" sensor (
Mavic 2 Zoom) is because of weight. Optical zooms are very heavy. The
M2Z was also a variable aperture 2x zoom, which lost a full stop at 2x. Fixed aperture zooms are even heavier, and more expensive.
This is exactly why DJI added the 7x telephoto camera to the
Mavic 3.
A 7x optical magnification has none of the problems of additional weight from a zoom lens, and the two cameras work together, allowing 1x-28x, which is up to a 4x digital zoom on each camera, with a gap between 4x and 7x.
The 7x telephoto is the solution, and, based upon the above article, the only legal way to video his son's soccer games.
