Q: 8. Why would a premium ‘L’ class lens like this Canon 50mm f/1.2 omit image stabilization in its design? This seems to imply that image stabilization might degrade the performance, or am I overthinking this?

A: A lens with a large aperture like this one would not necessarily need image stabilization, due to its ability to pull in a lot more light than lenses with a smaller or variable maximum aperture. Additionally, most of the R series bodies, such as the EOS R5/R6 already have stabilization built in to help with the lack of stabilization in the lens.
