Canon Community

Hi, I am shooting on a Canon EOS R, and using my tablet (Samsung S7 FE) connecting to Canon Connect in order to help me see products styling at the studio easier.  However, I find the live view on the tablet screen is so blurry, looks low resolution....

I can't find EOSR AC adapter and DC coupler, anyone knows where to find it? I want to be able to shoot without needing to change a battery for studio stop motion. Thanks.
