CANON EOS R5 R6 Adapted EF LENS Test...does it work???

NEW FroPack 2 Lightroom Presets https://froknowsphoto.com/fropack2/ (40% off) One of the biggest questions I've been asked since Canon released their EOS R5 and R6 is how is the Auto Focus with EF Glass adapted with the RF adapter? On top of that how is it with third party glass from Sigma and Tamron? I tested a 400 2.8 Canon EF and a Sigma EF 70-200 2.8 on fast-moving action. I used Face Detect as well as Eye AF. I think the results speak for themselves, what do you think? Download Sample RAW FILES https://froknowsphoto.com/r5r6efrf/ I'm GIVING AWAY A CAMERA VALUED UP TO $4,999!!!
