I was able to finally get a loaner from Canon to try out the R5. I just got it late yesterday and decided to try some backyard photography this morning. This was a frame from my first action sequence with this camera and I have to say I really think the animal eye detection rocks on this camera.
Thank you Brian Sump for spending some time with me to go through your preferred AF settings!!
