argyle43 We have more than one producer for our SLR Originals, and the angle depends on the camera and compatible lenses for that camera used.
For example, the Canon R5 C can shoot 8K at 60fps, but only has one pair of VR lenses, Fisheye 190°
Shooting 8K at true 60fps is not that common yet in VR. Professional cinematic cameras (Those huge ones like what they shoot movies with.) don't have VR lenses you can just pop on.
For example, and I hope I'm not breaching NDA, our upcoming 10k rig are two separate cameras at 5K 60FPS with their shutters synced. The angle of those scenes will depend on which lenses exist for them.
It is not the case that we in production dial some nobs and press some buttons and arbitrarily pick an angle out of a hat.
All together, there's literally going hundreds of thousands of dollars going into these things, in research and development, man-hours, hiring niche experts, testing, optimizing, making new workflows, etc.
Changes are never made on a whim. Even if they seem to be.
