Rob and Dave, having used my 500 f/4 is ii +- tc’s for years on my 5dmkiv’s I never saw the level of sharpness or af accuracy (even when calibrated) that your images with the R5 are displaying. Can you comment on this?
Well I am spoiled with the 1dx Mark III in that regard, but yes the extenders work flawless in my opinion. Yesterday I used my 400mm strait, with the 1.4x and with the 2x and really did not notice any AF performance issues. I will have to say the EOS R did a really nice job in that regard also. I do not even think twice about using extenders with Canon's line up. I will be curious if the RF extenders will offer any performance advantage over the current EF extenders.
Your observations are appreciated and what I am still trying to gauge is whether the same lenses and tc’s applied to the R5 will deliver performance I am not accustomed to seeing from a 5dmkiv? Are you using your IS or turning it off at higher Tv?
With respect to the tc’s it’s a bit of a Frankenstein connection having an ef lens, an R adapter, then an R tc, no? If the ef lens, ef tc and R adapter work fine, why change?
I never used a 5dmark IV but I feel the R5 is better then the 1dx Mark II and Amy agrees with what we have done so far with the R5. The TC's and adapter work great. I do not believe the RF TC with work with the adapter. If using the RF TC then you will have a RF lens to so no need for the adapter. The RF TC will not work with EF lenses. The reason for the change is to migrate everything to RF mount. I leave my IS on all the time.

So the RF adapter will work EF lenses, but the RF- TC wont ?
If so, how bad does it cripple it using a EF lens with EF- TC ?
