The R5 with the 100-500L lens is a really amazing combination. I tried using my Sigma 150-600C lens on my R5 but it wasn't focusing nearly as well as my EF 100-400L MKII. When I had the opportunity to get the 100-500 I did, then sold the other two and it was a great decision.

The image quality between the 100-400L MKII and the 100-500 is almost identical, and I didn't see much difference there which is fine because the 100-400L MKII was always an extremely sharp lens. Where the 100-500 steps ahead, like you stated, is the AF speed and accuracy, The AF speed is faster, and it seems to lock on more accurately as well.

I just recently added the RF 1.4x converter to the mix, and while I was never much of a fan of converters on my DSLRs, the RF version is really starting to change my mind. The only downside to the converter on the 100-500L lens is that is changed the focal range of the lens to the 300-500 range only, so you lose the short end...it's unfortunate because not having that range available anymore can be the cause for some missed shots. That being said, I shoot with the 1.4x now more than I do without it.

(100-500L with 1.4x) 700mm 1/3200sec f/11 ISO 2500

(100-500L with 1.4x) 700mm 1/1600sec f/10 ISO 500

(!00-500L, no converter) 500mm 1/1600 sec f/8 ISO 400
