Q: 5. Does this filter maintains communications with the camera body? Autofocus?

Q: 6. Does this help with lens flare on the Canon TSE 17mm? When I used my 17mm TSE on my 5DMkIII I rarely had lens flare. Now I have REALLY bad flare when using my 17mm TSE with my Vello adaptor on my R6.

A: The polarizing filter is to reduce glare/reflections. And to darken the color blue in things like the sky and water. It will not work to reduce actual lens flair. If the lens works fine on an EF mount camera, it could be that the adapter is causing it with that wide a lens and type of lens. The only other option would be to get the Canon brand adapter and see if that solves it. Canon Mount Adapter EF-EOS R BH #CAMAEFRF • MFR #2971C002 https://bhpho.to/3t6JznM

A: Unfortunately Kolari Vision EF-EOS R Drop-In Lens Adapter with VND Drop-In Filter does not include a clear filter.
