Laowa 4mm f/2.8 Fisheye Lens
The Laowa 4mm f/2.8 is a manual focus Circular Fisheye lens for APS-C cameras.
Best setting for 360Β°Γ180Β° 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:
And a 360Β°Γ180Β° panorama with just two pictures:
1/1000s f/5.6 ISO 100/21Β°

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 210Β° 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 180Β° Fisheye.
With the lens at a height of 1.6m, the 30Β° overlap is 1.6m*2*tan(15Β°)=0.85m (2ft 9").
Shadow covered:
It is common for fisheye lenses to have decreased image quality toward the edges, but not really an issue if it is only used for web/social media. The ordinary Tiktok brain does not recognize this deficiency anyway.
The two images were taken without a tripod, so the stitch does not 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.
And there are internal reflections at the edges with bright sun light:
