He let me get real close. at the St. Augustine Alligator Farm Zoological Park. My Canon EF 500 mm lens has a MFD of 16-18'. The RX10 IV can focus to 2.4. This is huge advantage.

Just for kicks, and because I thought your image was so good, I dug up a pic of the same type of bird to compare with my a99ii/Minolta 200/2xTC combo.
IMO, your RX10iv image holds up very well. Incredible performance from that 1" sensor!
