Q: 1. why won't this lens fit on my Mark III?

A: The RF 85mm f/1.2 L USM is not made for the 5d Mk III and only compatible with the new R-series cameras (R3/5/6/7/10). You require the EF version of the lens, but only a f/1.4 version currently exists (the EF 85mm f/1.2 was discontinued). https://bhpho.to/3mqrCPz

Q: 5. I am torn between the 85 and the DS. I am wanting to shoot Street photography with this lens, however I also need fast low light f1.2 for night Street. I do want bokeh and traditional bokeh from a 50 f1.2 is good enough. I'm leaning toward the standard 85 versus the DS as I don't want to lose a stop. Suggestions ?

A: Unless you want "Defocus Smoothing" at all times when shooting at f/1.2, I would say the normal Canon RF 85mm f/1.2 L USM Lens will be more versatile than the Canon RF 85mm f/1.2 L USM DS Lens. But, it's a completely personal decision based on your own esthetics.

Q: 8. Does this come with a case or bag for the lens?

A: Yes, this lens comes with a case.

Q: 9. 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.

Q: 10. Is this an internal focusing lens? I want to use the lens to digiscope with, so I can't have any movement externally after the adapter ring is screwed on.

A: Yes. Its focusing elements are completely contained and motorized within the lens, and the external positioning of the front element is unchanging.
