Borbin the 🐱

The TTArtisan 7.5mm f/2.0 is a manual focus full frame fisheye lens for APS-C cameras or a circular fisheye lens for full frame cameras. This lens has been used for all my Panoramas since Summer 2023.
The lens is remarkably sharp wide open and has an optimal Aperture of f/5.6 and much better compared to the 7Artisans 7.5mm f/2.8.

Best setting for 360°×180° Panoramas is at 0.5m(2ft) and f/5.6. This puts everything from near to infinity in focus:

A downside is the lens cap, which relies on friction from an inner fabric lining and can easily get lost.

Update

A set of 'Rubber Bands, Assorted Sizes' actually fixed the problem. Size #94 (3.15" × 0.75") works best, especially when glued in place with a contact cement adhesive.
