What does SLR stand for?
The definition of Single-Lens Reflex is,
"A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured." Wikipedia
360 DSLR?
Because 360 cameras can't view the subject directly through the camera's viewer, they cannot be classified as a 360 DSLR or 360 Digital SLR. Still, today's 360 camera image quality may surpass that of earlier DSLR cameras.
To the best of my knowledge sphere is the only true 360 lens on the market.
Cameras' equipped with a sphere lens do not require stitching or post-production software.
