Interesting results for sure. I read several posts about 'oh this 1.4x tc never comes off my 100-500!' and then i see threads with examples like this https://www.canonrumors.com/forum/threads/r5-detailed-lens-testing-of-rf-100-500-f4-5-7-1-vs-rf-800-f11-with-without-rf-1-4x-tc-for-super-telephoto-use.40240/post-887549 which clearly shows IQ loss when using the TC.

Theres another link in the same thread someone linked me which comes to the conclusion that the 1.4x makes things less sharp. Not sure what to believe anymore lol. Guess ill just have to wait to get them in my own hands and do some testing.
