It's amazing to me how such a little thing as an extended eye cup on a camera can make such a huge difference.
I just received my replacement eye cup for my R6II and how it fit perfectly and creates such an improved seal around my eye socket, blocking out the extreme light around me here in central Florida.
And, I got it from AliExpress for $18.85 with free shipping and it was here in a week.
They call it the KIWI soft silicone long camera viewfinder eyepiece eye cup for Canon R5 R5C R6 R6 Mark II eye shade protector.
I wish I had been able to find one like this for my last camera, which was a Canon R. But, I never could find one that was listed as fitting it.
