The Laowa 4mm f/2.8 is a manual focus Circular Fisheye lens for APS-C cameras.

Best setting for 360°x180° Panoramas is at the beginning of the infinity mark and f/5.6. This puts everything from near to infinity in focus:

The 4mm Circular Fisheye lens allows you to capture stunning and unique shots!

Interactive Panorama Laowa 4mm

On a sunny day, position yourself so that your shadow falls within the area of overlap (your shadow is perpendicular to the direction you are looking):

The overlap with the lens's 210° field of view at the seam is large enough to cover the shadow. Even for a nodal point adapter with a small footprint.
This is not possible with a 180° Fisheye.

With the lens at a height of 1.6m, the 30° overlap is 1.6m*2*tan(15°)=0.85m (2ft 9").

Shadow covered:

As with all fisheye lenses, the image quality decreases at the edges, but not really an issue if it is only used for web/social media. The ordinary Tiktok brain doesn't recognize this deficiency anyway.
The two images were taken without a tripod, so the stitch doesn't result in everything perfectly vertical and also has some minor misalignments. And with only two images, there is not much to vary. A nodal point adapter is recommended.

As with the panorama, there are internal reflections at the edges with bright sun light:
