Wanted to get an idea how my EOS R would perform with the EF 100-400 L II, 1.4xIII Extender, and, of course, the lens adapter. Didn't want to find out bad enough to go too far out of the warm house so this was taken from my porch. The rock was about 150' away.

The EOS R with that combination is 3/4" longer then my 5DIV with the same lens and extender. The EOS R combo weighs 4oz less then the 5DIV combo.
Have you also tried out that lens combo with the 2X extender as to AF? If so does the AF slow down with the 2X enough that it would inhibit doing BIF? At f/10 or F/11 one would need pretty good light. Another post here has sparked my interest in a possible new body. Just don't see any specs that cover this issue. Thanks
